Thread: Noise from a pully on front of 300TDi

Check that the idler pulley is not stuffed just below your compressor. I had to replace mine last week as the bearing had spun in the pulley and the local stealer wanted $170. The old man got one in Adelaide for me for $20.

Hi Gaz, thanks for that, i narrowed it down to that sort of region, where did you dad get the idler pully from? Was it new? MAtt

Ace,

If it is the AC belt tensioner this can be replaced with a "6023" bearing (sealed). About $10 worth.

You will need to press out the old one and like wise in with the new.

This is an easy job.

The same bearing is used on the main belt tensioner but is more of a fiddle.

Thanks OI, most helpful, i am certain its not mis alignment, as the noise turned up after ploughing through deep puddle, Yeah i know its no good for your rig but damn it was fun, and its more of a werring noise than a belt squeaking sound. I will take the belt off to see which pulley feels a bit rough when you spin it. Matt
