hi i tested the generator and i am not getting any power out of it i think that i want to put a alternator on it can someone help me with that on what the best way to do that thanks Vern

I recently had bought a 6 volt gen and then had a texas firm remanufacture it for 12 VDC. It took new field coils and rotor windings to accomplish. I am adding small lights to my D2

I have heard an alternator really doesn't cut it on a 2000 RPM diesel. Seems the rotational speed won't support a good output voltage. Also an alternator has to have 12 VDC applied to it always or you'll soon fry it.

Good Luck

Hi Al, Was the outfit by any chance Auto-lec? they have a web site on conversions but no pricing for a generator conversion. I havn't found anyone
in mid Michigan to convert mine yet.

almost forgot , 2bluejon, check the brush spring and retainer for rust and scale, these generators are not real moisture tight.

Your generator may need to be polarized,with everything connected up and the isolator switch on momentarily connect a jumper wire between the Bat and Arm terminals on the regulator,start up and check.

would there be anyway to convert my 6volt generator on my D4 crawler loader to a 12 volt generator? if so, how much would this run me. I also have a 1952 dodge pickup with a 6volt generator i would like to convert to 12 volt generator also. A young kid like me has to have a CD player in his truck right...

Find a good local starter/generator overhaul shop. It you have a good handle on the application or part number most places can change it over from 6 to 12 easily. Remember to get a new regulator and polarize all first.

Nothing wrong with an alternator on a diesel, even a slow speed diesel such as the old CATs, the problem comes when you do it the easy way and use one of those "one wire" Delco alternators. If these are used at the gear drive generator rpm, the diesel may never rev high enough to excite the one wire system and make it begin to charge. If you belt drive it and can gain some rpm from pulley ratio, then it might work ok as a "one wire".

If you use the regulator plug and an ignition switch or an oil pressure operated switch or some other means to supply battery voltage to the alternator regulator terminal, the Delco will excite at low rpm and most likely outperform any of the old generators. Also a lot cheaper to have repaired.

There are some direct drive adapter kits available to replace the CAT gear drive generators. These are the most expensive, but are a neat, simple installation. No chance of increasing alternator rpm since it's all determined buy the standard gear ratios.

Some folks have used a standard or shortened gear drive generator frame as a bearing support for a replacement (extended) shaft that can have a pulley on the end of it to drive an alternator/AC compressor etc.

Some of the older (than the U series) and newer (late U series and newer without the large single belt fan drive) tractors had a crankshaft pulley groove for a belt drive generator so you just have to fabricate a bracket to mount the alternator and tension the belt.
