Title: alternator pulley?
Post by: rob.79 on May 09, 2009, 01:23:56 PM
dont know if any one could help, but,
i had a squeaky drive belt over the last two days, everything looked ok, just fitted new timing belt, etc two months ago,  
then the battery light came on this morning,  :cry:
 looks like the bearings in the alternator pulley are shot, any one know if any one does these seperate for a denso alt?
dealers dont and the usual local motor factors cant get hold of one, had a quick look on Ebay etc... looks like gonna have to be new alternator!!!!!   :shock:
 ive taken it off and welded the outer part to the inner, so now its a fixed pulley, but not sure how long it'll last?

you need to look into maybe finding a local place that will refurb yours or i think you are gonna have to find a breaker with one to get the best price. i dont think you will get bearings for it.

It probably has a decoupling clutch in the alternator pulley. Chrysler don't seem to list a replacement, Try a local auto electrical specialist or get a secondhand alternator from a salvage yard.

yeah, its the actual 6 groove belt driven pulley which drives the alternator, it has a one way clutch/bearing, which i think is just there to reduce noise/vibrations and strain on the alternator etc.
 i've tryed a few auto electric places with no joy, :?:
called a salvage yard too, they would only sell a complete alternator!

looks like the i'll just have too see how long my welding lasts, it's holding up fine, for now.
