Model and type number are both 930 here. For the Fendt 930 Vario with Typ 930 you will find more than 500 parts for lighting, electrics and trailer couplings.
It sounds like a repeat, but it is correct: there is a Fendt 930 Vario with Typ 930 on its identification plate. This page lists more than 500 parts for that version only. A different Typ number on the plate means a different page.
Among the O-rings is the one for the fuel feed pump. If diesel weeps at the pump or the engine draws air after refuelling, that ring is an obvious first suspect. Work as cleanly as you can, since dirt in the fuel system ends up at the injectors. Wet the new O-ring with a little clean diesel, make sure it is not twisted in its groove and bleed the fuel system afterwards as prescribed.
Lighting and visibility come first in the cab: work lamps, including a corner flood light, gas struts for the windscreen frame and discs for the rear screen hinge. Inside there are push button switches such as the red hazard switch, handles, covers and tractor seats.
The linkage has a rotary potentiometer. At the rear you will find drawbars, automatic ones included, pins and connector heads for trailer air brakes. Under the bonnet there are seals, for example for the tank sensor, water pump gaskets and alternators. The brands are GRANIT, HELLA, ROCKINGER, Wabco and GRAMMER.
Unsure whether a part fits? Take the old one out, find its reference number and compare it with the replacement.
When replacing the water pump, always use a new gasket. Catch the coolant in a clean tray, clean the sealing faces so they are dry and without any grease and top up afterwards. Run the engine up to temperature and check the level again once it has cooled.
An overview of all versions together is on Fendt 930 Vario. If you run a different version, choose Fendt 930 Vario (Typ 928), Fendt 930 Vario (Typ 943), Fendt 930 Vario (Typ 951) or Fendt 930 Vario (Typ 957).
Elsewhere in the Fendt 900 line these tractors have their own parts page too, useful if you maintain more than one Fendt: Fendt 924 Vario, Fendt 927 Vario, Fendt 933 Vario, Fendt 936 Vario, Fendt 939 Vario and Fendt 942 Vario. The Fendt 922 Vario is also part of the line. The overview of the make is at Fendt parts.
