Case 580C Fuel Pump

[Pound]

Hello!

I have a Case 580C and I have attached a video of the fuel pump.

I do not know what the problem is. I am thinking about blowing air through the return lines toward the fuel tank.

I would appreciate any advice regarding the fuel pump. Thanks.

John

It looks as tho the throttle shaft seal is leaking and dripping from the throttle lever.
Try and Google: Stanadyne metering valve..
That might give u an idea of how the throttle comes out and the oring that’s leaking..

Will I have to remove the fuel pump?

No. But u do have to take off the top cover..
It’s easier to loosen the side cover to lower the fuel level inside the pump..& unless u shut the fuel off or pinch a rubber line, it’ll keep filling the pump..

I can access the fuel valve. Okay. I will replace the seals on the throttle shaft.

The o-ring is on the throttle shaft assembly?

Or the metering valve?

The “seal” is an oring that is both on the throttle shaft and the shut off shaft..2 orings total.
If u buy a 24371 gasket kit, they will have them AND extra plastic spacers (2).. that if added, 1 on each side, will reposition where the oring seals in the bore..
There is a clip that holds the throttle to the shut off.. THAT NEEDS TO BE REMOVED before the throttle can come out.
Try to find a video..
