The Massey Ferguson 6255 belongs to the 6200 Series. This page has more than 400 parts for it, with electrics, trailer couplings and lighting among them.
This page holds more than 400 parts for the Massey Ferguson 6255, supplied by GRANIT, Scharmüller, DANA Spicer, Cobo and HELLA. They range from PTO clutch plates and front axle shims to switches, work lamps and cab parts.
A PTO that slips under load or engages roughly on a 6255 often points to the clutch pack. For this tractor there are external and internal PTO clutch plates, O-rings for the PTO and a contact switch that monitors it.
Always renew the plates as a full pack. While stripping it, count how many external and internal plates there are and in which order, and lay them out on the bench that way. Soak new plates in clean transmission oil for a while before fitting so the lining is fully wetted. Replace the piston O-rings at the same time, because a leaking O-ring costs pressure and a new pack will slip just like the old one.
Adjusting plates set the mesh between the pinion and crown wheel. Measure the old shims with a micrometer and write down the total thickness before ordering.
The rating plate confirms you are working on a 6255. After that, the reference number on the part you took off is the surest way to match it on this page.
When a function in the cab stops working, start with the relay. Swap the suspect relay with an identical one from the same box and see whether the fault moves with it. If the relay is fine, the switch is next in line. A squealing or glazed belt on the air compressor deserves the same prompt attention, because without it the trailer brakes build no pressure.
