My 57 car generator apparently has a bad bearing as it howls when cold & when I put a stick on it & against my ear it feels really rough, & seems to be overheating in just a few minutes. I have a spare, both  have the end plate # FAS 10139-B The original also has the #B6A 10002-A on the case. ( One or more of these #s may be Canadian manufactured ) Questions- Unfortunately the spare has a smaller pulley with a slightly different offset, so it does not line up with the other pulleys. Why ?  Can I change the pulley ? Are they right hand thread? Also are the front bearings still available & are they pressed in?  ( please, no alternator conversion advice! My car is on a stock "vintage plate" so an alternator conversion is not a legitimate change.)

Paul:

The pulleys will interchange.  Keep any spacers with their respective pulleys.  Right hand threads.  Bearings are readily available at most parts stores and bearing supply houses.  They are a light press fit on the shaft, there is a retainer plate that holds it in the housing.

Paul,

Not sure, but I think the gen. pully nut is reverse threads. Increase torque to 65 ft. lbs. and don't overtighten the fan belt if you want the new bearings to last.

No mention of left hand threads in my literature re: generator rebuilding, so I am likely wrong. One thing to remember though, if the pulley isn't loose, and you want to save/resell it, be sure to use a gear puller to remove or you will damage it. A lot of generators out there with warped pulleys.

Thanks, I decided to have a rebuilder look at it, as the armiture in the spare one looked quite worn. He phoned and said it was wise that I pulled it out, as the rear bearing race has failed completely. No wonder it was noisy. Fortunately he says the electrics look ok.  Repair is $70...
