injector pump new seal kit

Post by winnerjd2010 » Sun Nov 21, 2010 9:04 am

I put new seal kit in roosa master pump (on jd 2010), put it back on crawler and cannot get it primed. I pulled the injector lines off at the pump and cranked it. It did spit some fuel, but not as much as I think it should. Had the throttle wide open, all fuel lines open, pump was mounted TDC, and matched punch marks on pump shaft to that in the motor...any ideas or experience in this would be greatly appreciated. Im going to pull the pump back off this week and take another look.

I think I may have figured it out...hopefully. I tore the pump back apart and found the plungers were stuck and not freed up. I got them freed up. Ill let yall know if that works

She breathes life again. The plungers were stuck. I freed them up, put the pump back on an shes running. Smoked white for a while, but after I got her warmed up she ran great.

its a roosa master db. I had the pump off for about a month and drained of fuel. I didnt tear into the plungers the 1st time to see if they moved freely so I guess they dried up because it took some force to push them out the 2nd time and lubricate them.
