Here are more than 190 parts for the John Deere 8320R in the 8R/8RT series, including trailer couplings, lighting and electrics, clearly sorted by group.
Night work, heavy draft and long hours in the seat: that is the life of a John Deere 8320R, and the parts on this page follow suit. There are more than 190 new parts that fit the 8320R, from GRANIT, Sauermann, ROCKINGER, Scharmüller and GRAMMER.
Work lamps for this tractor include oval LED spotlights intended for a whole range of John Deere R models. When an LED lamp starts to flicker, look at the plug before you replace the lamp. Moisture in the connector is the usual reason, and a dab of dielectric grease on the contacts keeps it out. If a lamp has misted up inside, the seal or the vent has failed and the lamp will not last, so replace it. Fit LED lamps on a solid bracket, as vibration on a flexible mount shortens their life.
For towing there are ball drawbars, drawbar frames and adapter plates, plus forced steering inner parts for trailers that need them.
The 8320R belongs to the John Deere 8R/8RT series. Start by noting the model and serial number from the type plate. A starter is matched on the pinion tooth count, rotation and flange, a drawbar frame on rail width and pin diameter. Feed pumps, thermostats and valves almost always carry a reference number, which is your safest guide.
After fitting a new fuel feed pump, bleed the fuel system before you try to start, and replace the fuel filters while you are at it. A leak on the suction side lets air in and can look just like a failed pump, so check the lines and clamps as well.
For the air brake valve and connector heads, keep the dust flaps closed whenever no trailer is coupled.
These tractors from the same series each have a page with the parts confirmed for that model:
The 8260R, the 8285R and the rest of the range are under John Deere parts.
