increase hydraulic pump pressure

warrenh · Oct 12, 2016

I would like to know if there is any adjustment I can make to increase the hydraulic pump pressure on my john deere 60 and 720 thanks warren

Service Manual should help.

you'll need to set your relief valve higher as well, or you won't see a difference with increased pump pressure.

Does it have a spring loaded bypass valve?

BE careful. You might not want to go much above factory pressure. The hydraulic pump drive isn't all that strong. I split a pump by shimming the relief just a bit past factory settings. It was not on a Deere though.

Increased pressure will not compensate for low flow . I don't have the documents at the moment but iirc 8-10gpm and 1200psi is maxed out for both.
What is the hydraulic load ?
