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. Once we removed the axle housing we discovered the differential end bearing and the race it runs against were bad. We removed the bearing cone off the differential with our bearing puller and torched out the inner axle bearing race. When installing the bearing on the differential, we removed the safety wire around the differential bolt, unscrewed the differential bolts and removed the outer half of the differential. Make sure you install the differential half to the exact location you took it off. In this instance both the bearing half and the main differential housings had stamped numbers to match up the halfs. These diffentials halves are machined to match exactly so it's important to put the matching halves back together as intended. We replaced the broken hitch pin, axle housing gasket, differential bearing and race and reinstalled the axle housing back on the tractor. The customers hitch arm was also replaced because t
he ball fell out of it's socket due to wear and tear over the years.
