D2 Generator information.

1102734 crosses to 8f3333, 6V, 19A, CW rotation, used on D2 and other Applications for both lighting, and pony electric starting groups.

My old Delco-Remy book lists the Delco-Remy regulator #1118873 to be used on the 1102734 generator under the Caterpillar 1954-1958 application section. Unfortunately I can't find any specs for this regulator number, and it's so old it might be difficult to cross to a newer model. Hopefully someone else has some better specs.😊

I would think any the 6V regulators off the Cats would work ok.

I would bet that if your local shop is any good, they can find a suitable replacement for that regulator. A lot of old cars, trucks and other tractors used that same style.

Thanks for the info guys.....I have an electric start pony motor but it is using a 12 volt battery.....how would that work with a 6 volt generator ?

If it was mine I would get the numbers off the starter and see if it's a 6 or 12 volt model. A 6 volt starter will work with a 12 volt power supply, but you won't get much out of a 12 volt starter on a 6 volt system. If you are going to use the 6 volt generator you'll need a 6 volt starter and battery. Good clean and true armatures and brushes on both units and nice big battery cables to help the current get to the load and the 6 volt system will work great.

I have used 8volt batteries in the older machines-they would crank the 6v starter over quicker and still charge with the 6v generator

The problem with using an 8-volt batttery is that I doubt that it will fit in the battery box of the older cats. The battery called for is a 6-volt group 1 type. The group 2 6-volt will not fit in the Battery box -too big. I would think that an 8-volt Battery is a group 2 Battery only. Could be wrong though.😊

Your Generator was manufactured on March(C) or April(D) 26th of 1956.😊
