Case IH Maxxum 5120 5220 Tractor Engine Starter Motor | 12V 10-Tooth CW | OEM 114800A1

Maxxum 5120 and 5220 owners tend to meet this part twice: once when the original gives up after twenty-some years, and once a fortnight later, when the wrong replacement arrives because somebody matched a model year instead of a pinion. Case IH fitted two starters to these tractors — the ten-tooth direct-drive unit sold here under reference 114800A1, and a nine-tooth gear-reduction unit under 114799A1 — and both were genuine factory fits, so the catalogues are not wrong, they just both apply.

Fitment and Purchase Checks

The reliable way through is almost embarrassingly simple: pull the old starter, count the pinion teeth, look at whether the nose carries a planetary housing or goes straight to the flywheel, and order to match, because a model-year chart will happily bless either unit and only one of them will crank your tractor.

The 5120 ran from 1990 to 1997 and the 5220 from 1992 to 1997, with the Ford-numbered crosses hinting at how much hardware these two shared with the era's Ford engines, and where any doubt survives the ten-second inspection, dealers and repair shops who send the serial, the engine details and a photo of the old plate with the enquiry get back a quote with price, stock, a dispatch date and warranty terms that hold where the part is actually going.
