Squeaking pulley

(1/2) > >>

drmike:
This is a 300 TDI and the top pulley is making an awful squeak. Applying WD40 makes it go away for a few minutes spray on grease a little longer.

I guess a bearing has gone. It's the smaller diameter pulley - easy to change?

beast5680:
check its not the belt that needs changing first my 300 had an awful squeak and it was the belt a new one cured it
if its the top belt tensioner that needs doing yes its an easy job to change the whole thing or you can re-bearing the old one if you want to

drmike:
Given that getting some WD40 into the pulley bearing seems to shut it up it seems most likely it's the bearing.

Also since posting I find you can buy just the bearing - once again: Easy job to change just the bearing?

bezzabsa:
most 300tdi's seem to have a squeek.. think its par for the course!
was told when I had my disco to use talc - as it sits in the grooves and quietens it down.

mud-club-matty:
