Hello, just purchased this tractor and of course it has problems. The most important one is that diesel fills the crank case. The mechanical pump was bypassed with an electric pump at the tank. The line from the filter back to the manual pump input was plugged. I think the pressure from the electric pump blew out a seal on at least one of the injector barrels to allow the diesel into the block. I can not find any information on the injector pump. It is a Slavia 2S90A diesel 2-cylinder air-cooled engine with a Motorpal PR2M7K160e110 injection pump. The Injector Pump element is #EM7K-12. Does anyone have a manual and parts listing for this pump? It is similar to Kubota pump.

i have a different model than yours but had a similar experience. the primer pump on the side of the injection pump was leaking internally. also on my pump there is a vent that allows any slobber to go to the outside rather than into the crankcase. mine was plugged. ....

Don't know when the electric pump was added. I have a note that the mechanical pump was bad. Mech. pump appears good when I had it out. Problem with pump is that the hand primer had the round hand piece missing so I think it wasn't screwed in not allowing the pump to work. I took a cabinet knob, cut down the knobs shaft, drilled the center out just a bit smaller than the shaft and pressed it on. Pump works as it should now. ....
