I just replaced all of the drive belts on my '84 240. The alternator tensioner wasn't like the ones on my other Volvos. It looks like you just hold the alt. tight and then tighten the nut. There's no actual tensioner ( with the long 10 mm bolt going perpendicular through the 13 mm lock bolt ). Am I missing something here. The alternator wobbles around when the car is running. I'm going to replace those rubber bushings soon, but need to get the belts tighter.

Thanks in advance.

Since I got a 1988 240 after living for years with the 1979, 1983, and 1984 240s, I was amazed at the long bolt mechanism for tingtening belts. I thought the older pry-bar method was OK. After all, my 1947 Chevvy, and all my Fords (1960, 1967, 1969) used that method.

Pry bar - I usually use the long 1/2 inch drive breaker bar. Snug the 13mm bolt somewhat tight, then pry with the left hand and wrench with the right.

Do the best you can, alignment and proper tightness won't be possible until the bushings are replaced,

Good Luck,

Bob

Step one is to check that the pivot bolt is properly fastened in place, then look to worn bushings. It is a bit of a chore to get the belts properly tensioned on the earlier alternators. I use a big ol' wrecking bar and gently lever the alternator away from the block while checking belts. Tighten the nut on the slotted tensioner arm and check again. Done.
