Can anyone tell me with what serial number the Farmall 140 went from 6 volt ot 12 volt ? and what serial number they went from canister oil filter to spin on ?

S/N 26801 to 45000 was 12 volt negative ground with a generator.

S/N 45000 to 57723 also 12V neg ground with some wiring changes.

S/N 57724 and above was 12V with an alternator.

For the spin on oil filter, the parts book says "machines w/serial no. 128241 and above" for the C-123 engine.
