How to check hyd pressure on 820 3 cylinder

XL cid A · Apr 14, 2015

Is there anywhere I can just screw a gauge in to check stand by pressure?

Since 830 3 cyl has open center hyd's it will not have stand-by pressure. Does tractor have rear SCV breakaway couplers. If so attach gauge to a male tip and insert into rear breakaway then activate control lever to check pump pressure

No SVC couplers. What it's doing it'll raise and and work until you put some weight on it then won't pick up. There's a leak
on the pump waiting on seal kit to fix that but was wondering if I had enough pressure when I get the leak fixed or how to
check it without the SVC

I think you should be able to check pressure where plug(parts key 5) attaches to dump valve.

I got the leaks fixed on the pump but still doesn't seem to have enough pressure. I tried to hook a gauge where you said but
couldn't get a reading. It would go up to about 500 psi when the lift stopped raising then back to zero. The lift works and
raise like it should just don't have enough umps with a load. I did notice that if I reved the motor up it would pick up a load
then but wouldn't unless you rev it up. I'm asumming the aluminum pieces are worn moor than I thought inside the pump.
Does bit sound like a week pump? I tried turning the pressure up but someone already turned it to the max so it didn't
change anything. This one has the small pump a Bosh and doesn't have power steering.
