How many pumps on 9N?

munk1958 · Jan 23, 2016

Does the 9N have more than 1 hydraulic pump? I am replacing the stripped drive shaft, hub etc, for the pump mounted on the front of the tractor. But I am also reading about another pump which is inside the engine housing? I'm just learning about these tractors, so please bear with me. Any help is greatly appreciated. Mark

The 9N only had one pump originally.
It is in the belly of the tractor, just forward of the seat.
If you have a pump mounted on the front of the tractor, ran off
a shaft from the engine crankshaft that was added. It was a
common addition to run loaders. Nothing unusual about it.
It would be completely separate from the one that runs your
3 point hitch though unless you have an aftermarket setup.

The 9N should have 3 pumps, the water pump at the front of the engine, the oil pump in the oil pan that provides oil pressure to lubricate the inside of the engine, and the hydraulic pump in the rear differential housing that provides lift power to the 3 point arms. If yours has more pumps, they have been added.

Okay, that makes sense. Thank you. Mark
