2.8CRD Timing belt due
 

Last changed the belt, tensioner, water pump at 64000 miles (103000km) in 2013. (Belt looked to be in mint condition.) with all VM factory parts Gates belt.
Only done 43000 miles (69000kms) since, but is on 8 years now, so planning to get done in near future.
Now that its on 172000 km should I replace any of the pulleys in addition to the above ?
(Did lube up the pulleys when the accessory belt was changed)
Accessory belt not that old with still plenty 'spring' left in the tensioner, but may purchase one to keep handy as the original went at 72000 miles (116000km)
