Hello everyone. I’m currently trying to rebuild an antique Caterpillar Fifteen. The switch for the magneto to ground on the dash has been replaced by a toggle switch and I remember on the old D8H. 46A sn. Also just about any machine with a starting engine like the D7E had the same switch. That the switch for the starting engine should be exactly what I need. Unfortunately the dealers don’t have the info on these old tractors anymore and I’m wondering if anyone in this group that has a parts book of these old machines, might have the part number of the on/off switch for the starting engine. If I remember correctly it only had 1 terminal on the switch and it grounded to the dash ground in the off position. It was a rotary switch with 2 mounting screws on the outside edges, looked like a miniature start switch. Thanks in advance for your help.
There maybe someone here that can answer your question, not sure. Have you considered joining ACMOC ( Antique Caterpillar Machinery Owners Club). There are some very knowledgable guys there.
If you can find the serial number, post it in case there was differences in machines. Someone probably has the info you are after. Simon C
The old 7t and 8t motorgraders had that same switch so gives you more places to look.
Switch part# for D4 is 4F4784
Currently 2 on ebay. Very proud of them!!!
