1946 Super V8 Hastings Generator

[dbstovall]

All:
I am currently looking at a no charge situation. As part of that, I removed the gen and am testing in the shop. The field shows 3 ohms to ground and the armature about 7 ohms. Hooking up to 6V it motors fine at about 500 to 600 rpm. The commutator looks good but I am going to replace the brushes and clean everything up. The rear bushing looks ok, no scuffing.


The current issue for me is that I noticed a lot of out of center rotations while motoring. I checked the movement: 30 thousandths up and down, 15 thousandths laterally. I popped the front plate off and there seems an inordinate amount of wobble, like the front bearing has self destructed. This is not normal, is it?


I tried to get the pulley off and no clip or nut. Is it pressed on? The brand name is Hastings and states it is a Replacement Generator. No model number. Hastings was a good company back in the day if this is the same one. I though I would see if anyone was familiar with this one before I destroy it trying to disassamble it.


Thanks, Dave

After some further looking: could this pulley be threaded on? And the snap ring is just missing?


Thanks, Dave

I have a generator that's got pulley threaded onto the armature.
Assembly, tighten pulley with armature in vise.
The clip is there to assure that you don't have a problem with it coming off in use...
I don't have one either.

I’d say if it doesn’t have a nut, it’s threaded on. I’ve never seen a pulley on a generator that is pressed on.

Yes I believe it is threaded on. It looks like the commutater has been turned down many times so mabe the last time it wasn't centered in the chuck and that is causing your wobble . It would also cause brushes to ware faster. I had a generator go out on me while traveling through Califonia and the replacement had this same commutater wobble but it got me home befor it gave me a problem. Tim

Ok thanks! I got it off ok, it was threaded. I found the wobble. The shaft is about 15 to 20 thousandths narrower where the bearing sits on the shaft. See pic. Since this bearing is ok, I would assume this happened some time during a bearing failure and a new bearing was put in without correcting the problem. Anyhow I am thinking this armature is NRTS and, considering the total cost of armature, bearing, brushes etc., and considering how beat up this one is, I will just buy a rebuilt.


Cheers Dave

I restore a lot of Ford generators and have seen quite a few armatures that were ruined by spun bearings. I have restored original Ford generators in stock. PM or email me if interested.

If the generator functions ,as is, then look for another armature to replace the worn. 1940 Ford used an armature with the threads and a recess for a ring. You do not show the complete pulley it may be early 1940 if so it will have the indented part number 01A-

Steve, I pulled the trigger on another rebuilt before I saw your reply. You are in Fredericksburg which is not too far from me. I will keep you in mind if I need another one.


No part numbers on anything. I assume Hastings ground them all off.
