Does the type plate on your Fendt 939 Vario read Typ 946? Then this page has more than 350 parts for exactly that version, including lighting and electrics.
Every part gathered here fits a 939 Vario whose type plate reads Typ 946. It shows only the parts for that Typ number, more than 350 in all, from GRANIT, HELLA, Wabco, GRAMMER and ROCKINGER. If your plate shows a different number, you have another version, and that version has its own page.
In the cab there are tractor seats such as the air suspended GRAMMER Maximo Professional and a seat with fabric cover, plus push button switches and pressure switches to replace controls that have started to play up.
For lighting you will find LED work lights for working after dark, beacons such as the HELLA Quasarino, and brackets to mount a rotating beacon on the roof. A loose bracket lets the beacon shake on every bump and shortens the life of the lamp, so it pays to replace both when one is worn.
Engine and cooling parts include alternators, temperature sensors, for example for the air conditioning, other sensors, seals and the cap for the expansion tank. At the rear there are automatic drawbars, springs for the three-point linkage and Wabco connector heads for the trailer brakes.
Only open the coolant expansion tank once the engine has cooled down. The system is under pressure when warm, and hot coolant can spray out. If the tank slowly loses coolant without any visible leak, the cap itself is often to blame. The valve inside no longer holds pressure, and a new cap is a small job that saves a lot of fault finding.
Check the drive belt and the cable connections before ordering a new alternator. A slack belt or a loose earth cable cause the same complaints. If the alternator really is at fault, compare the reference number and mounting with the old unit, and take one more look at the type plate so you do not order a part for a different version of the 939 Vario.
The general overview for the model is on the Fendt 939 Vario page. For the other versions, go to the Fendt 939 Vario (Typ 954) or the Fendt 939 Vario (Typ 960). When in doubt, compare the reference number on the old part with the description in the shop.
Other tractors from the Fendt 900 range with their own pages are the Fendt 924 Vario, 927 Vario, 930 Vario, 933 Vario, 936 Vario and 942 Vario, plus the 922 Vario. The whole brand is listed under Fendt parts.
