860 hydraulic pump priming

[Dan (NYC)]

I was hoping someone could identify the ports on my pump. It is a piston pump and I think I need to re-prime it. Currently the lift arms are not working, though there is enough fluid and it is in position control mode. I did look in port A and tried adding some fluid to it but that didn't work. Thanks for all you information!

Remove the "C" plug and crank the engine over but don't start it. Fluid should spurt out of the hole.

I usually take out the "c" plug and screw in a fitting with a nipple and length of hose to where you add fluid at plug beneath seat.Remove fill plug and insert hose and start engine at low idle. That way fluid comming out of pump will not be wasted by going out on the ground and pump will not be starved because the fluid is going back to sump.

Ok,take C plug real loose(after you make sure you have the hydraulic fluid full)and while its running,loosen that plug untill the air bubbles stop coming out.Just at an idle.It may take 2 or 3 times.Dont worry too much about the arms coming up untill bubbles stop coming out of the pump.
