Rick, If standby pressure is that low good chance adjustment may not bring up to normal stall limit. Should take a turn or less to get it in range. Most often this is caused by a worn out / leaking stoke control valve. The valve and seat can be replaced in tractor if you know how to do it as I have done it many many times on many different models. The seat and valve is a assembly that is matched set. Kinda pricey but common to replace them on older tractors. If pressure cannot be achieved that is where I would go next. Set it to 2250 psi. DW

I envision springs and small parts flying toward my face under that tractor! LOL! What you are saying makes sense... I am wondering why the front loader really has no reaction whatsoever... maybe due to weight?! Or is it that the real problem lies with the loader valve.

[quote="CVPost-Rick3"](quoted from post at 16:16:57 06/24/20) I’m getting zero Psi without the lever activated and only 700 with it activated.[/quote]


You said "I scooped up a big load of gravel and took it/ dumped it and was going to back drag it with loader but it wouldn’t respond except to go down" and "used red" offered a good suggestion that something could have happened to the loader valve.


Have capped off the feed yet to the loader valve?

Until you you this, to be absolutely sure there isn't a high pressure leak to return there your tests at the remote couplings really don't mean anything, and there's no valid reason to wrench on the pressure control on the pump.

That being said, it may well be that the loader valve is just fine and the trouble IS in the pump, but IMHO, it would be prudent to rule out the loader valve BEFORE pursuing changes to the pump.

Yes that is on the agenda. I wound up down thereyesterday and had a few minutes to mess with it. Got the right gauge fitting for the rear remotes and checked it. It’s probably going to be a couple weeks before I’m able to go back and take the loader out of the equation. I appreciate everyone’s help as I narrow down the cause of this issue.
