Fiat
Fiat tractors and only tractors on this page: the 640, 780 and 880, the 1000 and 1300, the 480 and 580, and the 3000-series. Each is listed in the Machinery Parts Finder on PartsForMachines with starter motors and alternators matched to the model and the price on every listing. Nothing here is for a Fiat car or van. The same tractors sold in North America as Fiat-Hesston, and that badge has a page of its own.
Fiat tractor starters and alternators: 640, 780, 880, 100-90, 130-90
Starter motors and alternators are listed against the Fiat tractor model with OE number and voltage on the listing. The number off the old unit finds the new one through the cross-referenced catalogue, and the Fiat-Hesston or New Holland number appears on the listing where the ranges overlap.
Start with the number on the old unit if you have it; the header search takes an OE or part number directly. Otherwise the Machinery Parts Finder: Fiat, the tractor model from the dropdown, then starter or alternator. Decal gone, photo to 07754288583 on WhatsApp. The Compatible tab confirms before you order.
Batteries by size and oil to the period grade through the Oil Finder head the wider range, then filters, tractor seats by cab type and the rest, matched by specification. Not in the Finder? Ask Simon.
