Hi All,

I just grabbed these pics out of the parts manual for the 05 KJ, they show the diff/tranny breathers for an 05 CRD KJ. Just wondering has anyone tried to extend these up to the Engine bay to make water crossing less troublesome?

Front Diff Breather

5 speed Auto Transmission (Note: this is the 5 speed that comes with the CRD - see pic below for the 4 speed used on the 6 Cylinder Petrol 3.7L KJ)

4 speed Auto Transmission (This is the 3.7 Petrol Engine Tranny!)

Rear Diff/Axle (the parts list shows a Corp 8.25 but shows leaf suspension if you look at the pics.....right axle, wrong suspension -doh!)

Selec-Trac Transfer Case

The red circles show the breathers and attachment points.

I was considering buying some 5/16 fuel resistant hose and joiners and extending the tubes up to the rear of the engine bay to stop water ingress into the diffs.....they are pretty low to the ground in stock form. Anyone done this?

Cheers

Wilmo

Also, found this info on L.O.S.T for those of you that want to know.....

The front diff breather is under the battery tray. Kinda high. Easily extended.

The transfer case diff is run ALL THE WAY to the auto tranny's dipstick tube. VERY HIGH.

The rear diff is run up to the gas tank area. Kinda high. Easily extended.

The tranny breather is behind the engine right underneath the [passenger side in Aust] head. You can't see if from the top, but you can easily get a hand to it. Just need to crawl on top of the engine a bit. Pull out the little spash gard. Slip in a [tube joiner] already connected to a longer piece of hose and it is done.

I'll try and verify if this is all correct and report back.

i took the battery tray out over the weekend and was wondering where the tube went :%

Wilmo

I found all the breathers tonight, two of them are on top of the bell housing for the tranny, squeezed between the gap in the body and the bell housing (tranny and transfer case breathers), both accessable just enought to push a connector into once you remove the plastic valve on the end.

The transfer case one is accessable from under the car on the passenger side, the tranny one is accessable from the drivers side of the engine compartment, its down next to where the tranny dipstick tube disappears under the firewall.

You have to hunt around a bit under the car to feel the 5/16 rubber hose that could be only these breathers.....both are plugged with a white plastic valve. They seem easy enough to extend with a bit of fiddling around with connectors and tubes.

The rear diff is easy to spot, and looks like you could add a length of hose to it and direct it up through the chassis rail to the petrol filler area. The front diff is under the battery cover as Fouros found.

Interesting pics from the manual, one of the pics shows leaf springs?? Must be the US model?

Wilmo

I think someone just stuffed up the diagram or used a generic picture from a Corp 8.25 manual......the KJ's in the US all have coil springs like ours on the rear.

Well I extended the breathers last weekend:-

Rear diff now routes up to and wraps around the fuel tank filler - very easy to extend, just pull out the 'splash valve' in the end, and join another piece of tube to it with a 5/16 joiner and route through the chassis rail up to the fuel filler area. It is visible wrapped around behind the fuel filler opening. Seems tight enough to just sit there.

5 Speed Auto trans one was a complete PITA - very tight on top of the tranny to get your hand in there, what I did was pull out the plastic 'valve' splash protector which is in the open end of the tube (after much exploration and frigging around - very difficult), pushed in a 5/16 plastic pipe joiner with some 5/16 hose attached to it, then led the hose up to inside the engine bay up high on the firewall, then put the splash valve back in the end.

Transfer case one was easier - although the end of it is hard to reach (wedged between the body and tranny as well, near the tranny breather), you can feel where the tube runs from the Transfer case over the top of the tranny, then along the tranny on the drivers side of the car. I cut it where I could easily (about half way along the tranny), then pulled the now loose part out (cable tied in with other electrics so don't pull to hard!). Then, popped in a pipe joiner where I'd cut it and attached a new longer piece of tube and led it up to the engine bay, then put the 'splash valve' back in the end of it.

Also extended the front diff breather - it was at the base of the battery - easy to get to without removing the battery, just extended it up about 20cm so its closer to the underside of the bonnet. Also re-inserted the 'splash valve' for good measure.

That's good information Wilmo. Would you like to produce a "breather extension kit" to go with the upcoming snorkel?!
:)

So it's basically 4 x 5/16 plastic pipe joiners and a load of 5/16 hose. And a lot of frigging around! Where did you get your pipe and fittings from?

Wilmo
17-02-2006, 03:52 PM
Pipe from Repco - I got 3m and it was just enough. Joiners - you can use 8mm plastic ones or 5/16 brass ones. The plastic ones I got from Supercheap Auto, the brass ones from Auto One.

A word of warning for the Diesel People! The Factory Routing of the Front Breather SUCKS! Two days before the MJOC convoy left for JAD last year, I noticed that the breather on my dad's vehicle ran around to the front of the engine rather than just straight down and underneath. On closer inspection, it was resting on one of the pullies! ..Opps, the pully had actually chewed through the front diff breather, and they tend not to stock these in the country for some reason. Another thumbs up for brighton though who picked up the Jeep from West Melb, replaced it with one from another vehicle, routed it away from the front of the engine, and droped it back to me.

Hmm....will have to look a little more closely as to where that one goes - I only really investigated the visible end that I extended - up near the battery.

They don't really need to "stock" them do they? It's just a bit of 5/16 rubber tube. I got mine from Autobarn.

I was grovelling about in the dark tonight checking out where they go, I haven't fitted mine yet but I'll be sure to check that one in a bit more detail when I do.

Yeah - its just 5/16 tubing. Anyway, mine does sit in the general area of the pulley, but is some distance away from it - I suppose it could flick up and touch the pulley with some intense off-roading, so I might just put a cable tie around it and fasten it down to be sure.

I've just spent the morning grovelling around under my Jeep, with limited success. The rear diff, front diff and transfer case are relatively easy to do. The f@#king transmission is impossible. I can see the end of the breather, but there's just not enough room to get at it between the body of the Jeep, the front drive shaft and the exhaust. I'm guessing that, although it's still hard to do, there's a bit more room under the CRD? Has anyone with a 3.7L done this? Here's some pictures of the underside of mine;

Any ideas that don't involve dropping out the transfer case or growing some smaller arms and hands with a couple of extra wrist joints are welcomed!

On the up side, fitting the Rocky Road diff-guard was an absolute doddle!

Can you not pull that plastic valve out of the end and stuff in a joiner with a piece of pipe attached? Mine was also VERY difficult to do, took me about an hour of fiddling around on my back under the car assessing how I could hold it whilst I pulled out the valve, then pushed in the connector. Luckily I do have fairly small hands.....

monster
27-03-2006, 02:16 PM
Pull out the plastic valve? I can't even get my hand to it!
:D

I reckon if I took the exhaust off (or a least disconnected the exhaust from the downpipe, and moved it to one side) I might be able to get one hand to it, but I don't think there's any way I'd get two hands to it to hold it and pull the plug out and put the extension in.

How much 'slack' is there in the pipe? Like the transfer case breather, once I'd unclipped it from where it was attached near the dipstick I was able to pull it up into the open making adding the extension easy. I'm thinking I could get one of those bendy grabby claw things (used for retrieving parts dropping into inaccessible places) and use that to pull the pipe down into a more easily reachable place. But how long is the pipe? From the original diagram you posted it looks very short indeed.

Lord only knows why Jeep decided to leave this breather where it is, why not just extend it up to at least where the transfer case one was?

The pictures I posted previously were for the CRD 5 speed transmission. The 4 speed transmission is as below:-


http://www.microwise.com.au/jeep/breathers/4speedauto.jpg

The end of the breather is clipped to the tranny dipstick. Which breather are you actually looking at then? The transfer case?

The 4 speed auto breather looks heaps easier to do than the 5 speed, which was stuck on top of the transmission housing - and a very short tube.

The transfer case one was easy as the tube is quite long, it crosses over the back of the transmission to the drivers side then runs up along side it on the drivers side of the transmission to around where the dipstick is (at least on the CRD - probably about 50cm long). I cut it about half way along the transmission where it is easy to reach, then pulled the loose end out. Then I extended the end that was still there.

Does the diagram above ring true for the tranny you have?

monster
27-03-2006, 09:08 PM
Hmm, no that doesn't ring true. My transfer case breather runs all the way along the side of the transmission (like yours) and up to that clip on the dipstick! And yeah, that was easy to extend by first unclipping it and pulling up the slack.

My transmission breather is lying on top of the transmission just about where the transfer case breather disappears under the bulkhead at the back of the engine bay.

It's impossive to get to from the engine bay 'cos it's too far down and there's not enough gap between the bulkhead and the engine, and I can't reach it from the bottom 'cos there's too much stuff in the way!

If that diagram's accurate though then it should be easy enough to see where it actually enters the transmission; on the driver's side, just in front of a little square sensor thing, or something. But I don't see how the end of mine can be where it is, if it originates where it's supposed to on that diagram! I'll check it out tomorrow.
:?

Thanks for the info Wilmo.

Wilmo
27-03-2006, 09:16 PM
Sounds just like the 5 speed Tranny in the CRD then! The Tranny breather on my CRD was also *almost* impossible to reach. It took me a long time to work out a way to get my fingers to it to pull the valve out, then manouevre the new extension into the open end. It was on the passenger side of the CRD too....sounds like yours is on the drivers side? Check and see if that attachment point on the rear of the 4 speed - as the diagram shows - is within reach. If so, maybe attach a new pipe there and lead it forward to the engine bay would be the easiest to do? Good luck.

monster
27-03-2006, 09:36 PM
Yeah, I think mine's the old 45RFE, yours is the new 545RFE, which is basically the same thing. And the 'other' diagram you posted is the 42RLE which is more normal for KJs! Confusing!

It's visible from the passenger side of mine. Based on the diagram you've posted it looks like it's basically just poking out of the connection to the transmission, rather than having that "U" shaped bit of pipe looping over to the driver's side as in the diagram.

I'll check it out a bit more tomorrow.

Wilmo & I had a look at whats involved in extending the breathers on my Sport & montioned the above fact. Well Im one of the sufferers of this problem, my front diff breather is almost in half. The pulley has just about cleft it in twain, so I guess ill be down my local repco purchasing some 5/16 rubber hose & 4 joiners.

Now I wonder if my 4yr olds hands are strong enough to get to that tricky one? Surely they would be small enough. Hey Pzver maybe a diff breather extention party at my place & get my kids under our KJs.

09-04-2006, 10:48 PM
Hey Palla, I am not sure that I would even get close to getting to anything either. I just had a look under my KJ and not sue at all. Maybe my 7 year old son could do it :-).
Maybe we just leave them to it and go to the pub for a few drinks and come back and bob's your uncle all done.
Page 10 Jeep Action Mag, a fellow Jeeper reported getting water into his diff just by driving in the rain on the Pacific Highway. Costed him $250 to have the oil changed.
I was worried about this when I did the 4wd course as there was a water crossing involved. I was praying to God that nothing was going to happen. About 2-3 months ago when I had the left rear axle seal changed due to it leaking I asked Jeep to tell me what the condition was of the oil prior to them doing anything and they said it was fine. But I imagine it wouldn't take much for it to get in.

I've kind of advanced with mine.

I thought that maybe there'd be some slack in the transmission tube, and I couldn't get a hand to it (or so I thought, see below) so I had the bright idea of getting one of those bendy grabby things that you can use to retrieve small parts from inaccessible areas and using that to grab the breather and pull it down into a more sensible place. First go I managed to get hold of the end of the tube, pulled it and it turns out that there's no slack in it at all. The splash valve popped out a treat though. So I now have a bare breather tube waving about on top of my transmission.

In an attempt to correct my stupidity it turns out that if I take off my wedding ring and remove a sizeable chunk of flesh from the outside edge of my thumb then I can just touch the (now open) end of the breather. But at this point I'm so contorted that there's no earthly way I can even reach the extension tube lying just out of reach on my driveway, nevermind slide it up and connect it to the existing breather.

Next step, being as my transmission now has no protection from water ingress, is to take off the exhaust, since I think that'll hopefully allow me to get my hand a couple of precious millimeters closer.

My other (or possibly; additional) idea is to get a bit of wire poked into the end of the breather and use that to slide the extension up, so guiding it into the open end of the pipe.

Yes, I am getting desparate.

Wilmo
11-04-2006, 07:43 AM
I sympathise with your pain......I think the diesel is tad easier as the exhaust is on the other side.....

Yeah, that's what I'm thinking (we've got exhausts on both sides!) so hopefully with the exhaust loosened it'll finally be possible!

Well I've repaired the front breather hose & extended it up to near the primer pump. The rear was a doddle & is up in the filler recess.
The transfer case breather has wedged itself into an inaccessible position down by the oil inspection tube. Cant get to it from above or below, can get to the hose easily front top of transfer case thencut & extend from there but then wont have breather cap (purchase a new one?) I have even removed the coolant tank to try & get to it.
Then there is the gearbox.... There is absolutely no way I can get a decent enough purchase on it to remove it, can just get 2 fingers to it & spin the cap around.

I have lost the battle but by no means lost the war......

monster
17-04-2006, 03:35 PM
OMFG!
I've done it!

The transmission breather (at least on the [5]45RFE) is UNBELIEVEABLY difficult to extend. However my "wire" technique makes it just possible. On the CRD I think it's slightly less impossible since there isn't an exhaust in the way. According to the diagram posted of the 42RLE that transmission should be relatively easy.

What I did was;
- Used a bendy grabby thing to pull the splash guard out of the end of the existing breather.
- Got a bit of stiff-ish wire with a slight bend at the end of it, the bent bit being just slightly longer than the connector I was using.
- Slide the connector onto the end of the wire, manoeuver the wire into the end of the existing breather, so the connector is now lined up with the end of the breather
- Use a long flat-bladed screw-driver to push the connector into the breather
- Take a short-ish bit of your extension tube (say; 6 inches) and use the same wire technique to line the end of that up with the connector that's now in the breather.
- Writhe and grunt around under the car until you manage to slide the new tube (which is poisitioned correctly, thanks to the wire) onto the connector.
- Your breather is now extended downwards into a more accessible place.
- Run some more tube down from the engine bay and connect it to the extended piece.

Hey-presto! Bob's your Uncle. I now have even more respect for those surgeons who do key-hole surgery. It would seriously probably have been easier to drop the transmission out!

But it's done. Hurrah!

4 out of 4!!!!! Today I picked up some skids (transmission & transfer case) & while I was under there looking at how it fits in, I used a pair of pliers with a 45* bend on the tip to grab hold of the transmission breather & pulled it off. Then it was simple to fit the extention & run it up next to my extended front diff breather. There we are all done.

While I was under there tho I did see another breather sitting above the fuel tank towards the rear bumper just poking out. Any ideas whats that all about?

Wilmo
25-04-2006, 05:39 PM

err...kinda two years after this thread... but i can confirm that there are two breathers on the fuel tank.

When i was installing the fuel tank bash plate - i removed the tow hitch and saw another breather that i'd not seen before (nor heard about on the forum). It's to the left of No4 in the pic. The breather cap was jammed up tight above the tank - just visible.
I extended it up to the fuel filler location, just like the other fuel tank breather.

So, there are FIVE (edit- read SIX!) breathers that gotta be done on the KJ: front diff, transmission, transfer case, rear diff, the long fuel tank breather that goes halfway up the fuel filler tube AND the short fuel tank breather (on top of the tank).

Hi I noticed my my front breather hose was almost in half from rubbing on the a/c pulley Looks like youse have already discovered this i found a metal tab under the battery box to run the new hose through to keep it out the way I changed my front diff oil and it had water in it I recomend changing it if your hose was badly cut.
About raising it up shouldn't the valve keep water out?

28-06-2008, 09:25 PM
Yes I relocated mine, same problem, pulley rubbed through. They now sit just under the bonnet up against the fire wall. Thats the front diff, transfer case & gearbox. The rear diff lives behind the fuel filler door. The gearbox is a real biach.

I'm slowly working through my breather extensions. This mysterious one on top of the fuel tank - just how do I find it? I have the fuel tank bash plate and the tow bar back there and I really can't see it at all. Do all KJs have them (mine being a 2007 CRD)? The tank breather on the filler neck I have, but why is there another one? Is there a tank drawing somewhere that shows it?

Different KJ build years seem to have differing approaches to breathers. My 2007 did not have anything like the breather locations described by Wilmo, they certainly were not get-able from the top back of the engine. My transfer case breather (while having a long hose) was trapped up at the very top of the transmission and seemed to be secured to something else, the only way to get it off was to pull the damn thing loose (the breather, which was trapped up there, fell out when I started the car - it was burnt and the end melted black and was open to the elements (I assume exhaust pipe is the culprit). The tranny breather hose was all of 40mm long (only enough hose to attach the breather cap), and yes on top of the tranny but attached to the metal breather neck, and can only just be seen. Had to pull the breather cap and insert a hose connector and hose to route to the firewall. I now have the front diff, the tranny and transfer case breathers all extended to the firewall near the fuel filter primer button. Rear diff was easy and is up the filler neck. I did not see a need to extend the tank filler as it is already up the neck. Now as to the mystery sixth breather (the one that is on top of the tank) I just can't find a way to access it. I can see what I assume to be fuel hoses running from one side to the other (as per the post on the tank lift pump - complete with diagram. See this post:

http://www.ausjeepoffroad.com/forum/showthread.php?t=76223&highlight=lift+pump

I stuck a small inspection mirror up there but I cannot see the breather. The attached photo shows the short breather on the fill cap as per the diagram (from someone who dropped their tank). Does anyone have a suggestion for accessing the tank breather in the diagram? I'm glad that the rest of those are finished - a dirty job and I'm still finding Jambo mud under there.

I had to drop the towbar to get to that tank top breather - there was simply no other way to do it. I could see it and reach it with a extra long handle needle nose pliers but could not do anything with it from there. I have the fuel tank bash plate there as well. I propped up the tank plate from underneath and blocked the towbar with some plastic milk crates and pavers. Once the bar dropped down a little I could get my hand in there and remove the old breather cap and insert my hose extension - it now resides with the other rear breathers (up the fuel filler neck).

I measured all the breather heights from the pavement (giving me my depth limit I guess): Front breathers all at 1100mm, and rears all at 900mm (but also housed in the filler neck which I think would work like an inverted bucket to trap air if water rose from below). Happy with that, and I will make up a bracket out of aluminium to mount the front three on (and their little breather filters - don't think much of the Jeep plastic caps).

Had the day off today so thought I would not waste the day and do the breather hoses.
Front and rear diffs were easy.
Transfercase was a little annoying.
Transmission was a pain in the ar*e.
Scratched up arms but got it in the end.

All were exactly positioned as described.
Everyone should do this, the transmission one was way too low.
Everything now 1100mm high. Will need to look at a snorkel down the track. This modding is addictive.

Hi All,

I just grabbed these pics out of the parts manual for the 05 KJ, they show the diff/tranny breathers for an 05 CRD KJ. Just wondering has anyone tried to extend these up to the Engine bay to make water crossing less troublesome?

Front Diff Breather

5 speed Auto Transmission (Note: this is the 5 speed that comes with the CRD - see pic below for the 4 speed used on the 6 Cylinder Petrol 3.7L KJ)

4 speed Auto Transmission (This is the 3.7 Petrol Engine Tranny!)

Rear Diff/Axle (the parts list shows a Corp 8.25 but shows leaf suspension if you look at the pics.....right axle, wrong suspension -doh!)

Selec-Trac Transfer Case

The red circles show the breathers and attachment points.

I was considering buying some 5/16 fuel resistant hose and joiners and extending the tubes up to the rear of the engine bay to stop water ingress into the diffs.....they are pretty low to the ground in stock form. Anyone done this?

Cheers

Wilmo

Please can these pics be re-posted?

No. Wilmo originally posted those photos in February 2006, and he is long gone from AJOR. Unless arrangements were made at the time he left for someone else to take over hosting these photos then he has probably deledted them from a storage server. Some of his photos (like in the CRD FAQ thread) were taken over by me and are now hosted by me. But this thread was not active at the time so the photos are gone.
