From electrics and lighting to steering and front axle parts: for the Massey Ferguson 4225 in the 4200 series you can choose from more than 400 matching items.
Plenty of farms have relied on a Massey Ferguson 4225 for years, and sooner or later the front axle, the rear axle and the electrics need attention. This page holds more than 400 Massey Ferguson 4225 parts, from GRANIT and from brands such as Eaton, Cobo, DANA Spicer and GRAMMER.
For the drivetrain there are gear wheels for the planetary drive in the rear axle and adjusting plates for the bevel gear in the front axle. Sealing rings and O-rings in many sizes keep the oil where it belongs, and ball joints take care of the steering.
If a gear in the planetary drive has to be replaced, inspect the planet bearings and pins as well. Drain the old oil into a clean tray and look for metal particles, which tell you whether something else in the rear axle is wearing.
The adjusting plates set how the bevel pinion meshes with the crown wheel. When you strip the front axle, keep the shims together by location and write down the thickness of each pack. Refit them in the same build up and the tooth contact stays the same, which avoids a whining axle. If in doubt, check the contact pattern with a little marking compound on the teeth.
Play in a ball joint is quickest to find with two people. One rocks the steering wheel with the engine running while the other rests a hand on the joint. A knock or movement between ball and housing means it is time for a new one.
Around the engine you will find V-belts, starter motors, gaskets for the exhaust and thermostat, and seals for the fuel tank sensors. A V-belt that squeals under throttle or shows glazed flanks is already slipping. Re-tension a new belt after the first working day, as fresh belts stretch a little at first.
For the cab there are tractor seats, mirrors, headlights and work lamps, along with a rocker switch to operate the work lamps. A headlight with moisture behind the lens is best replaced as a unit, since a new bulb in a wet housing will not last.
Start with the serial number on the type plate. The 4225 belongs to the 4200 series from Massey Ferguson. Many parts such as sealing rings and gear wheels carry a stamped reference number, which you can compare with the product details. For sealing rings and O-rings, measure the inner and outer diameter and the thickness of the old one.
