More than 250 parts are listed for the Deutz-Fahr DX 6.50, a tractor from the DX 6 series. Trailer couplings, lighting and electrics are some of the groups.
On a DX 6.50 with a lot of hours behind it, the first complaints usually come from the cab. A door lock that no longer catches, a gas strut that will not hold the rear window, a push button for the work lamps that sticks. This page covers those small jobs and the larger ones too, with more than 250 Deutz-Fahr DX 6.50 parts.
There are push button switches, gas struts for the door, front window and rear window, door locks and air suspended tractor seats. Fit a gas strut with the piston rod pointing down. That keeps the seal inside bathed in oil, and the strut holds its force for longer.
For towing there are automatic drawbars and drawbar frames from makers such as Walterscheid and ROCKINGER. On a hitch that has seen years of use, check the locking mechanism and the coupling pin for wear as well, not just the jaw.
Before fitting a brake cylinder repair set, look at the cylinder bore. If it is scored or pitted, new seals will not stop the leak, and the whole cylinder needs replacing instead. With the crankshaft seals, take care not to fit the new seal on the exact groove the old lip has worn into the shaft.
A blocked vent in the tank cap lets vacuum build up as fuel is drawn off. After a while the engine starves and stops, even with a full tank. Before you suspect the lift pump, try running with the cap loosened. If the engine keeps going, a new vented cap solves it.
Your type plate should read DX 6.50. For seals, shims and sealing rings it all comes down to size, and the quickest way to get that is from the old part, which often has a reference number moulded or stamped into it. Besides GRANIT, Walterscheid and ROCKINGER, you will find PROBOSS and GRAMMER here. Other tractors from the brand are on Deutz-Fahr parts.
