Alternator belt adjusting - Page 2 - Benzworld.org - Mercedes-Benz Discussion Forum

I am running into some of the similar problems: Former mech bent the tightening bolt, bracket, etc...

But the issue that I have-which I cannot figure out-is clearance: I took the entire adjusting bolt OUT-and still do not have enough movement to get the damn belts on!

I have a '82 300 SD, with AC. I have gotten the runaround from the local auto parts stores as to the correct size, anyway. Any hints?

This seller seems to have the sizes of the belts you need

I hope the link works for you - if not go through the choice menu.

On my OM617 (non turbo in a W123 no A/C so slightly different) I have removed the viscous cooling fan ('cos I wanted electric) and the best way I have found of putting belts on and off is to remove and refit the pulley on the water pump and then only do a small adjustment at the alternator.

83 CDT.
The Conti's were on very tight at the end of their lives.
I installed Gates from RockAuto.
Easy fit.
