Generator Info Needed

Hello All, I have what I was told is a D4/7U generator. The tag on it says Delco-Remy model #1102734, serial 0G12. It was said to come out of an electric pony start 7U. I can't seem to find a cat number on the unit. Is it a 6 volt generator or 12 volt unit? Is it possible to install a pulley on the unit inplace of the gear which is missing now? Thanks for any Info. Joe Giraud:)

If it came off of what you stated it would be a 6 volt starter. It shouldn,t be too hard to find a gear so I,d keep it that way & save a lot of messing around.I,m sure someone will come back that has a gear & if they are missing you,ll need a nut & washer & key too.

It might be possible to replace the gear with a pulley, but that would be just the beginning of the modifications. You would need a pulley to fit the large wide belt and a bracket to mount the generator and allow you to tighten the belt, and a new longer belt. Some very late U series tractors had multiple standard V belts and a tightener which could be replaced with a generator in a bracket.

All in all, if you are contemplating going to all that trouble, you probably could just use a delco 12V alternator, 12 volt battery and really spin that pony:D

I would look for a gear or sell it to someone else and go the alternator route.

D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time:D

SJ,CCjersey and Jon, Thanks a bunch for the advice and info. I am going to add electric start to the pony on my D2/3J. I would like to keep it all original cat stuff. Thats why I was asking if a pulley could be used in place of the gear which was gone when I picked up the generator. My cat came with the lights only generator, hench no voltage regulator or battery, just an on off switch located on the generator. I have most of the parts I need except the bellcrank-1F7631 and the rod-1F7632. I want to keep all the rope start parts so I can always return it to it's original configuration. Anyone know where I could find these two parts. Thanks again. Jo:) e Giraud

Joe,
I looked in the parts book for the 5J and they list only 1 delco model number along with all the CAT generator part numbers listed. It isn't the one you have. I expect your generator could use a regulator or you could probably control it with the switch and a circuit breaker and an ammeter between it and the battery if you wanted. It is also possible your new generator could clamp in the same bracket as the lights only one. I would try it and see.

I didn't know you already had the bracket, belt and pulleys.

Hi ccjersey, I don't have the pulley or the belt yet but I do have the bracket to the lights only generator. I will see if the new generator I have will fit in the bracket. I have been able to find the correct voltage regulator for it. The hard part is going to be finding a pulley for it. Oh well, thats half the fun -finding the parts you need.
