Looking after a Fiat 85-90 from the 90 series? Choose from more than 250 matching parts, with lighting, trailer couplings and electrics well represented.
Plenty of Fiat 85-90 tractors are still doing a full day's work, and keeping them that way comes down to good wear parts. This page holds more than 250 parts that fit the Fiat 85-90, from GRANIT and from makers such as Cobo, LUK, MAHLE and Eaton.
For the steering there are ball joints. To check one, have someone rock the steering wheel back and forth while you hold the joint. A knock or movement inside the joint itself means it is due. A torn dust boot lets water in and the joint will not last long after that.
For the three point linkage you will find lift rods and seals for the lift cylinder. If the linkage slowly drops with the engine stopped, oil is often getting past the piston seal of the lift cylinder.
Clutch kits, double clutch pressure plates and thrust bearings belong together. When the clutch is renewed, fit a new thrust bearing as well, because it sits deep inside and nobody wants to split the tractor twice. Gear wheels for the driveline are available too. Check the flywheel face for scoring while the tractor is split.
Engine parts include turbocharger and exhaust manifold gaskets, piston sealing rings and O-rings, for instance for the brake cylinder. Alternators and gear reduction starters cover the electrics, and drawbars and lamp glass round things off. A gear reduction starter is worth considering if the old starter struggles to turn the engine on cold days.
Among the air filters you will find secondary elements. The inner element is a safety filter. Do not blow it out with compressed air. Replace it instead, for example at every second or third change of the main filter.
The model and chassis number of your 85-90 are on the rating plate. For a clutch, lay the old plate and pressure plate side by side and compare the diameter and the number of springs. Seals and bearings usually carry a size or a number you can look up.
The 85-90 is part of the Fiat 90 series, and several other models from it have their own page: Fiat 55-90, Fiat 60-90, Fiat 80-90, Fiat 90-90, Fiat 100-90 and Fiat 110-90. If one of those works next to your 85-90, check its own page for what fits. All other Fiat tractors are under Fiat parts.
