You have to change the oil every time you change the oil in the engine. The filler is the large 15/16th plug on the front/top of the governor housing, the level is a 1/2"spanner size on the side of the governor and the drain is a 1/2"af spanner size underneath the housing,(or could be immediately beneath the level plug depending on pump).

The governor itself is a system of weights, spinning round and using inertia to control through linkage, the position of the fuel pump rack.

The oil in the governor housing is only to lubricate this weight system. Diesel from the main pump is allowed to leak into the housing diluting the oil. The oil level will build up due to this and slow the action of the weights. When the tractor was a working tool, the oil level had to be checked weekly to keep the level down. Some pumps leak more than others so don't worry if the level rises quickly or doesn't rise at all as long as there is oil/diesel in the housing.

When changing the oil the governor holds about 1/3rd British pint(sorry have not worked out metric equivelant). The pump should be filled until oil runs out of the level plug, then allowed to stand until oil stops running out. This is then correct.

This information also applies to the mechanically governed Super Majors.

that's it ?? (it just sounds too simple to me, no pipes, no connections, no filters , no nothing to be maintenanced ??)

What will happen if the level gets to high ? (I am using her for about 5 years, did 2 oil changes in about 100 working hours because of the sludge in the engine, but never checked the level in the governor)
What oil do I have to use ? Same as the engine (15W40) ?

ps : 1 pint is about 0.57 Liter

Yes its that simple. Thats why this pump became extremly popular.

The same as the engine. I would not worry just start checking and refilling from now on.
