Tutorial - Replacing the bearing in a 300TDi airconditioning compressor pulley.

Just doing this now. On mine there are no shims. However, there is this:

which is some sort of spacer.

I gather the step where you turn on the ignition is to lock the clutch so that you can undo the bolt against belt tension; No good on mine as it keeps shredding belts, which is why I'm doing the bearing.

So, I used one of these;

This is the new bearing number, as a couple of others have posted;

Attachment 120933

Sorry, not as clear as I'd hoped.

And this is the new bearing, with the old;

All pretty straightforward, except mine was rusted together a bit. Care needs to be taken taking the front plate thingy off. A puller would be best, buy I don't have one that fits, so careful levering works, but it's best to lever on the plate, not the pulley, as there is soft material on the pulley you can damage.

Thanks Dave for this. Putting mine back tomorrow, just picked up my belt from Mario.

Hmm. Might take me a while to get used to posting pics...

Thanks. Handy tutorial and saved me lots of money.

Hello. I had to do this this week, but could not find the bearing under the numbers in the thread. After some calling around, I found (and used) 30BG5222-2DSE.

I have attached a couple of photos to show:
- Where the washers are found as you disassemble.
- The parts laid out in order of removal.

Thank you for listing the part numbers.. That is very useful
