You looking for a seal kit? Or a new pump?

I can buy the kit at my local injector place it's just a couple of o rings and washer and a gasket for cap. If you can get it apart without damaging the gasket and pull the throttle pin you can just replace the o ring till your kit comes in.

so that pin will slide out once I take the top off and linkages off?

Do you think it can be done without taking the entire pump off?

thanks

Yes, get a pic of it.. if its a CAV pump, they're really easy to do, and usually can be done on the equipment.. Up here the kit to do the entire pump costs $25.. a little more involved.. I've done 3 of them this year already

Before and after.. suffered from the same throttle shaft leaks

I"d try to get that serial tag cleaned off to find out exactly what pump it is.. It doesn't look like a CAV DPA pump to me, looks more like a Roosa Master like on our JD 350B crawler (shape of inspection cover on the side).. I've never had that one apart, but I don't imagine it's all that much different.. I'd get the kit, then reseal the entire thing... I'd probably dunk it in paint remover and get it all cleaned up rather than fighting to keep paint chips out of places they oughtn't be

yes its a roosa master.

I got it all apart.. it had a "J" type washer holding them together.

I have it all back together but haven't fired it up yet.. got to late last night. Might go out after eating and try it.

I heard they had lots of power too.. in fact they should have been a little heavier to really use the power. Looks like a nimble little unit that can get into tight spots

Our JD350B is about 12K lbs.. the rocks I've dug out and moved around with that thing are surprising... rocks a good mid-sized excavator had a hard time with... a lot of stuff on it is getting pretty tired though.. clutches, pads, rock guards, and front main seal all need some work
