Massey Ferguson 35 Repair

Tractor came in with a broken three point hitch pull arm pin and a bad hitch arm.
 These pins are held onto the axle housing with a locking nut inside the tractor. You must remove the axle housing to replace the pin. The pin has a taper to it so when you remove the attaching nut, you must hit it quite hard. We use a large punch about 1" in diameter to hit the pin. You do not want to damage the axle housing.

New differential bearing installed by removing differential half and pressing bearing on.
Differential half had to be removed to press the new bearing in place. Pounding the new bearing on with the differntial in place would have destroyed the bearing on the other half of the differntial and possibly damage the ring and pinion set. After reassembling the differntial and new tie wire was installed in the differential bolts.  New Hitch Pin (above). Notice the taper on the left.
