Quincy 210 freewheels

[brent5631]

I just started my quincy 210 up for the first time in a few years and it wont build pressure. It ran fine for manynyears but has sat for awhile now. It doesnt make any hissing or leaking noise. Just runs like the unloaders arent working.

Anyone more familiar with these that could tell me what to start checking?

Thanks

Do you have oil pressure?

Yes, gauge shows pressure. About 30 lbs.

I would pull the hydraulic unloader out of the side of the crankcase and check the seals. This is the square brass device that has the airline from the tank going into it and the airline to the unloaders coming from it. It should cut off the air supply to the unloaders once oil pressure has been established.
