I have been fighting significant alternator
belt wear on my perkins
4.154-200. I checked the alignment early on but evidently not very well.
I was re-looking at the situation and noticed a slight twist in the belt where it hit the lower crank pulley on the alt side, starboard. Port side is VERY difficult to see but with effort I could also see a slight twist in the belt at the lower crank. The fresh water
pump pulley & the alt pulley look to be in alignment. The crank seems to stick out further from the engine
by maybe 1/16".
Any 4.154 owners ever see this issue? How did you solve it?
I'm guessing at this point I could put washers/spacers on the fresh water
pump to push it out and take the alt to a shop and have them shim out the pulley as well.
I'm surprised to see this in the first place.
