Ford 3000 4000 5000 6600 Tractor Starter Motor | 12V 10-Tooth CW | OEM AS100300AP

There are more Ford 3000s, 4000s and 5000s still earning a living than almost any other tractor of their generation, and most of them have outlived at least two starters already, because a machine that gets used every day eventually wears out the part that starts it. The unit sold here is the 12 V direct-drive replacement with a ten-tooth pinion turning clockwise, listed under AS100300AP and cross-referenced through the Ford numbering system that these tractors were actually built with.

Fitment and Purchase Checks

Ford revised these part numbers often enough that even the dealers double-check, and the years involved — the 3000 from 1965 to 1975, the 4000 from 1962, the 5000 from 1965 to 1976, the 6600 from 1975 — overlap with a dozen related models from the little 2000 through the 6610 that shared the same starter family.

Which is a long way of saying the old unit settles the question faster than any chart, so take it off, read the number and the tooth count off it, and photograph the plate if half a century of damp has had its way with the stamping. Dealers and repair shops who send the serial and engine details over with the enquiry get a proper quote back — price, stock, dispatch date, and warranty terms that actually hold where the part is headed.
