I've got a 2002 Volvo 4,3 GL-B with an SX-M drive. Is there a torque specification for the two bolts that hold the trim motor onto the pump assembly?
Full story below if you are interested.
The trim motor was making alot more noise then usual last year so I decided to do some investigation. The motor housing seemed loose so I tightened the bolts down, but that resulted in the motor not working. The pump is under a hatch that can dump water right on the motor when it rains so I figured this might be part of the problem. I opened up the motor but to my surprise everything looked pretty good inside. I did hit all the contacts with contact cleaner before reassembling it. I noticed that if I leave the bolts slightly loose I can almost get it running 100% smoothly, but as soon as I try to dial out the last bit of "rattle" it gets worse again. I think my problem is with the two bolts not applying equal pressure to both sides of the motor housing. I should also mention that even with all the excessive noise the drive can still be raised and lowered smoothly.
Thanks,
Dan
