Vevor pressure gauge kit

The problem seems to be system wide, including the foot pedals. I wonder if switching to synthetic oil would help. I've been told that this machine doesn't need any special oil, so I'm using a conventional Schaeffer hydraulic oil.

There are spring kits for the poppets inside aren’t there? Wondering if the springs are getting soft?

I'm not sure, I thought you were referring to the spring kits that go on the outside and press on the joystick base. I wonder if there is a diagram from Rexroth that would show how these are assembled.

As with any spool or poppet valve, they all have springs and springs can lose tension over time. That or seals become brittle or swell.

I've not worked on one of these before. Where to start disassembling to access the springs and seals?

I haven’t done one before but I’d remove the top and see if the plungers pull out.

Now I finally understand what you guys are talking about... Sometimes I have a thick head.
