4.154 Alt Belt Alignment

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.

"Looking" is not going to be near as good as putting a straight edge on each pulley and seeing where it hits the other pulleys.

Re: 4.154 Alt Belt Alignment

I have had belt wear due to both misalignment and rust pits in the pulley grooves.

First shim up the pulleys so they line up perfectly with a straight edge. Then if you have any pitting in the grooves you can try to carefully file them out in place. A better approach is to take them off and put them in a lathe and smooth out the pits with a file.
