I have a 96 hdj80r manual. Had it for about 100k, long engine rebuild about 40k ago. Alternator replaced about 15k ago, and recently I've started towing a heavy load, so have been looking for more output, and largely changed the way I drive, mostly keeping the motor in the 2200 to 2800 range. I've also fitted a better turbo, had the injectors replaced and fitted a large fmic.
It started throwing belts about 1000 ago, since then I've had multiple failures. Sometimes the ac belt would give up first, other times one of the fan belts. I changed the ac idler first, the compressor pulley feels fine. No good. I've just replaced the harmonic balancer with a fourth new set of belts, and within an hour it inverted the rear fan belt. Didn't come off but obviously would have done, and the belt is u/s.
I did notice the alternator pulley is hot. Too hot to touch. It feels fine, but I'm beginning to wonder if an overloaded alternator could cause this issue? I have 3x batteries in parallel in the vehicle (been fine for a decade that way) and now and Andersen 12v connector out to the trailer, which might want 40a.
Otherwise, the fan pulleys are mounted on the water pump, right? Should this be my next focus area?
Very much appreciate any sage counsel here.
Cheers,
Alex
