4.0L Rear Main Seal Replacement when changing clutch
Hi Jeepers,
Planning on replacing the clutch as preventative maintenance around 170K.
I have all the parts to do the rear main seal on the shelf, it's been a minor leak for a few years.
I can see from lots of posts you need to remove the main bearing cap and drift the seal in.
I can also see this looks to be a bit fiddly when people have done it by just dropping the sump.
Question I have, seeing as I've opened everything up, If I remove the flywheel, is it possible to tap the new seal in "flat" parallel with the block, instead of drifting it round from underneath as is done when you only remove the sump.
It seems this drifting round is the part of the repair that is most likely to damage the new seal going in.
If it's not going to make it any easier I might as well just leave the flywheel alone so I don't have to replace the bolts. (I know I might end up having to replace the flywheel, but hopefully catching this early means the convex surface is still good)
Appreciate feedback from someone whose done this on the bench and knows the block.
Ta.
