Thread: Discovery 2 TD5 Tensioner Pulley

Ah yes, it's all coming back. It was the idler I replaced the bearing on. With the tensioner I replaced the pulley which obviously came with a bearing. Still pretty cheap though.

Get a quote from Mario/Heather (Roverlord). Quicker, and probably cheaper than OEM!

Check your fan bearing too while the belt is off I recently bought another D2 TD5 that was making a fair rumble

Greasing the idler bearings is part of my maintenance routine each oil change. However, if I feel a resistance when turning the bearing in hand, I change the bearing. Your choice of bearing, SKF etc.. At the moment I have a squeak when shutting down, panicked a bit when I thought it may be the harmonic balancer, but got down & dirty & found it to be the tensioner bearing. For the life of me I can't remember if the tensioner pulley bolt is left or right handed. The mysteries of life.

OK, i checked the vicous fan bearings and seems alright, just the belt was squealing and i changed the belt and it was ok

How do you grease the idler bearing?

There are two idler bearings in the drive train. Remove the belt, remove the bearings, carefully remove the plastic covers , clean the bearings, grease same, replace the covers. Simple.

Have to say, I don't have ACE, and I'm counting the tensioner bearing. A bit vague, I admit.
