..............n that the free wheeling mechanism of the a/c compressor also could have a very slight screeching sound.
Can that one be changed alone or would that mean a new compressor?

I‘d like to get that area done in one move when I have it worked on...
I would be very surprised if that is shod - Mine has 20 years 843000 km and still OK

and - worn belts that pull into grove type pulleys also moan - at the pulley
2000 Patrol GL 4.2D - Still strong after
Eight Hundred and counting THOUSAND KILOMEEEEEEEEEEEEEETERRRRRRRRRRRRRRRRSSSSSSSSSSSSS

The sound really is very little, so maybe it would be a bit early to change something.

The sound I started this thread about stopped a few days after driving through water.
So maybe it was just a bit of dirt which was trapped in one bearing, what would you say?

Tear the stuff open and change something or rather wait and see?

Get yourself a 6303 bearing (17mm Id, 47mm OD and 14mm wide). This is the idler bearing which I still believe is the one causing the problem.

You can keep it in your tool box untill the bearing starts causing problems again Sooner or later, you will need it.

You will need a 14mm socket on a ratchet, and a small (1/4" drive) 10mm socket on a long extension as well as a pair of internal circlip pliers to change out the bearing, and you will probably bleed a little bit in the process.

Honestly, it's such a mission to change out in the field, that I would just do it before it really starts causing problems.

Added note: this same bearing is used in the TB42, TB45 AND TD42, however the tools needed to fit it may vary.

That‘s what I‘ll do: get this bearing an have it changed in the workshop or do it mysel, I‘ll see if I think I can do it.

Dirk, hy gee gewoonlik redelik lank waarskuwing. Ek dink nie dis nodig nie.
