What about clearance?

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

1982 Mercedes-Benz 300SD Sedan - Filters & Belts - Page 2

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.

1992 190E 1.8 <=>2.0 201.018 => Daily driver

1981 300D (non turbo) 123.130 => Project car - stripped to the bone

Free and legal FSM download => Ask for help if you get stuck!

Don't leave that there I'll take it to bits

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