[diesel_mercedes] Re: Pulleys & Belts - 300D

IIRC ;

There's some allen headed bolts holding the pulley sheaves to the
dampner , they were prolly not tightened sufficiently as they're a bit
difficult to reach and one must use a long ratchet and support the head
as you tighten them because they're 4" recessed and the allen bit wants
to slip out sideways when you're looseneing / tightening them ~ I had
just this problem when doing my water pump last summer , I wound up
replacing a few of the allen screws when they partially stripped .
