Operating PSI and GPM of AW wrecker hyd.pump

[73m819]

Lookig for the operating PSI and GPM and pump frame specs for the hyd. pump for the m62/m246/m819, I think the m60/m108 uses the same pump but not sure, I have the AW tm, it does not have the pump specs. nor the pump frame specs.

In the M62/M108 austin western crane PDF I have, all I could find was 1200psi operating pressure, 1500 rpm, 35hp. No GPM.

That is what I found in the same tm, is the 1500 psi regulated pressure or raw pump pressure?, also looking for the pump frame specs.

Found some more, pump is vickers, MJ-3C4529A Googleing this didn't bring up any info.

The ord-9 gives the number as vickers 126274, there was no help with that number either

I know this is for the M939, I just thought it may be a little useful. I don't know if the systems are universal or not. I've read 1800 RPM myself.

1500rpm, 1200psi. Pump pressure is set with relief valve, no such thing as raw pump pressure.
m936 is a completely different system.

What I need to know is what the pump can put out, and at what gpm, I know about the 1200psi relief valve, what I want to know is can I run a SEPERAT circuit that I could pull 2000 -2100 psi (both cirects NOT in use at the same time)

trying to get a lot more psi out of a pump that is not set up for it is doable BUT the pump gets HOT and the life of the pump is short.
