What are the alternator bushings for? 700 91

posted by  someone claiming to be Bruce on  Sun Oct 7 10:14 CST 2001 [RELATED]

The other day after I was unable to get the proper adjustment of the drive belt, I noticed that there were two rubber bushings on top of the alternator, with a bolt thru them and a hex nut on each end; and the alternator pivots at this point. When I turned only one bushing-nut it started to angle the alternator position. The other one brought it back, kind of like carpenter's wood clamps work. So I held one tight and ratcheted the other one as much as I could. Not sure what the heck I accomplished though. The one bushing now has a little gap of a space between it and the metal housing it sits in, but it was flush on both sides before I messed with it. Messing with the bushings has given me more bolt length to adjust, which it needed. Don't know why though. The other bushing is flush on both sides.

So, what is its purpose and how is it set properly?

I have to tighten the drivebelt adjustment bolt almost all the way in order to get the proper tension on the belt.

Btw 1 , I noticed there is also one lower bushing too. Anything I need to know about this one?

Btw 2, I am having a hard time finding those long 7 mm, OD X 1.00 mm thread pitch, X 5" long bolts. Anyone know of a seller of metric fasteners that stocks these bolts. I break them all the time when doing the adjustments. I am currently using bolts from a local hardware store, but I think that the bolt grade strength is too low. They snap too easily. My local Volvo dealer wants $20.00 per bolt with bracket. Don't need a bracket and don't want to start a bracket collection either - insanity!

Thanks,

Bruce
