Quincy 308 takes a long time to fill

Rebuilding the top end. How do I replace the valve discs? I cannot figure out how to open the valve cages.


Approximately how long should it take to fill a 50 gallon tank to 175PSI. Currently about 35 minutes.

Bill says... hello Kevin. 35 minutes to fill a 50 gallon tank seems to be a awfully long time to me, so I suspect, as you clearly do, that your compressor has a problem.

I were you, I'd chase down Quincy for those details, unless we have a visitor that can provide the answers you need:

308 Long Fill Time
by: Peter

I just got a 308. It was filling very slowly. I rebuilt the valves and put a new gasket on the head. Still a slow fill time. 35 min+ to 150 psi 60 gal tank.

Talked to Quincy. A new 308 @540 rpm will fill a 60 gal tank in 25 min. Not a fast pump but high pressure.

They are rated to run at 400-900 rpm.

I had a 1-1/2 hp motor with 4" pulley making the rpm 480. I ordered a 5.25 pulley to get approx 640 rpm. It should be better.

You do not want to over amp the motor.

Good Luck.
