M belly pump,continued

I now have the extra belly pump apart. I have taken 2 pictures. In the first picture I am holding the lever off of the small ball. In the second picture I am pointing to the ball with a welding rod. Question, the ball is flat where the lever hits it. Is this an indication of wear or should it be flat. I can see machine marks on the ball so I think it is ok. The inside of the pump was extremely clean and had a light coating of grease on everything, but no oil in it. I know someone had been in it before, because I found a #3 finish nail for a cotter pin. Does anyone know of a supplier for the gasket? When I put it back together how do I get the pump lever from outside the pump into the (socket?) inside the housing? More questions later. Thanks, Ellis

last gasket i got was from case i-h. you can get gasket material from napa or farm and fleet and make your own. to get the lever hooked, you kind of put the pump to the housing kind of off to the side and slide it to position to get it to hook up.
 
When assembling the pump into the housing, attach the operating lever to its cross shaped fitting so you can have some leverage when going together. Good luck.
 
I took mine apart when I replaced the input shaft seal.
I can't remember though what the check ball looked like.
The pump was working fine so I didn't change anything.
I reused the same housing gasket. Still holds.
Putting the two halves back together and lining up the linkage was the hardest.
The weight of the two halves makes it difficult.
I seem to remember suspending the two halves with twine while I lined up the linkage.
I found a dip stick in mine.
 
When you pull the rod back into the lift position there is a detent that holds it there until a cylinder hits the end of stroke and the hydraulic pressure spikes. What you are pointing to is the mechanism than kicks the lever out of the detent position. When the pressure spikes up the relief valve opens and the oil is diverted to a hole that the cap you are pointing to covers. The oil flowing out under the cap pushes the cap back until it pushes against the detent arm and allows the lever to return to the center, hold position.
