Hi
How do I check the Oil level in my Simms injector pump?
I need to change the oil but I cannot find the screw which indicate the max oil level

Do any of you know the model of this pump?
I have looked for a serial no but cannot find it

Thanks for your help

It depends what pump you have on your tractor. The early Super had a vacuum governed pump that does
not have oil in it, it mis lubricated by the diesel itself. Later tractors had a Simms MiniMec pump
which has oil in the governor housing to lubricate the mechanical governor only.

I have marked the fill and level points, the drain is underneath. The plugs go into an aluminium
housing so be careful and do not over tighten them.
 
Nearly identical pump powers my Ford 655A TLB. Except direct gear driven from the other end, and with lift pump mounted right on the side. When I bought it, I serviced it right away, finding that a previous owner did not. So, eventually I had to have the pump rebuilt. The bearings fell apart upon disassembly.
 
Thanks for your explanation.

I have just uploadet a photo of my pump.
I cannot find the oil level screw.
Is this pump lubricated by the diesel oil and if so, why are there a big nut on top for adding oil?
Do I need to add diesel by this inlet?

At the bottom of the pump, where the red arrow point, I removed the screw and drained the liquid, which was not oil.

On the side of the pump, I cleaned the plate with the model no, which says P4596

That is not a pump for a Super Major originally. Do NOT put diesel into that plug. Is there a plug on the bottom of the bulging bit at the back? If there is, drain it down and put 2/3rds of a pint of engine oil in through that top filler.

It possibly will not be oil that comes out of the governor housing, diesel from the cam box is allowed to seep into it and will dilute the oil. That is why, back in the day, you were told to check the oil level every week and change the oil every time you did the engine oil change.
