alternator for 89PT40

[jim riordan]

Yes those rear belts are hard to deal with. I had to buy a thinner belt so that i could thread it through the small opening. someone before me had put a wider belt in (somehow) when i examined the old belt i found that the pulleys had worn down a ridge in the belt anyway.

Thanks toeveryone for the information provided. I removed both alternators today. It was not thatbad.While I was down there I decided to clean all points
of contact as Mike sugested, including the starter. I had them tested at the alternator shop and was told that one was producing 50 amps and the other one was producing 60 amps. I decided to replace them both with new ones by Leece-Neville 110-555JHO160 amps. Everything was going well. I was even ahead of schedule untill I tried to remove the belts off the engine pulley in the back. I can't for the life of me squeeze them through the small gap between the pulley and a plate. I can't see down there but I can feel a small gap with my fingers. It's just not big enough to slip the belts through.

Does anyone know how you are suppose to remove thebelts?? It appears that I have to remove the back bumper and the back plate that's attached to the frame.ThenI will be able to see the pulley on the engine. I'm hoping there's another way. I would really like to put new
belts back there. Suggestions appreciated.

I was told by an alternator shop to never jump start an engine if both
banks of batteries are discharged. He said to charge the batteries
before trying to start. He said it will ruin the alternator to run it
if the batteries are drained. I replaced my alternator 2 years ago.
