1993 Volvo 940 B23ft with A/C:
I've read as much as I can find on this topic but still have a couple questions.
The problem is that the alternator belt jumps around a bit because it isn't aligned exactly. The belt hasn't come off or broken. It has three new poly alternator bushings.
One thread mentioned that there may be more than one standard accessory bracket and that could cause alternator belt alignment issues even after changing all the bushings out. Does anyone have more specific information about that? The thread mentioned 1993 being a unique year but didn't specify what is unique about it, how the bushing fit is different or if there are different bushings that should be used.
Along with new alternator and power steering belts, I replaced the three alternator bushings (the replaced ones were also poly and fine) but the fit of the bushings doesn't seem right to me. They slide in to the bracket without needing to press them and once in place, are not completely snug on the alternator, even with the long screw torqued down and after tightening everything. This time, I used a washer in the top rear bushing location, between the alternator and the bushing shoulder to place the alternator as far forward as possible and to get a tighter fit (pic below).
With new belts, and bushings and everything adjusted and tightened, it was quieter on startup and idle but its still jumping around like before. I haven't driven it yet. Not too worried as its been like this for a while without problems but I'd like to know why it isn't right and not think about it again.
Washer at the top rear bushing:
Its hard to see but you might be able to tell that the alternator spool is not dead straight
Any input is much appreciated
