How much pressure in the JD Hydrostatic steering?

[mars1952]

Hi: I have a JD 4300 12/12 Sync Reverser. It has two hydraulic pumps one for the remotes and rock shaft (2500psi) and one for the steering. How much pressure does the steering pump put out? I have looked online and in my tech service manual to no avail.
Thanks, Marshall

I think it's the same as the main system pressure-but not 100% sure. Nothing in the steering section of the FSM?

In my tech manual for my 790 they have a section near the back that covers power steering relief valve testing. It's 1200-1400 psi for the 790.

The steering system on the 4300 is set to 1500psi, according to my
manual, p 9-8. The only diff betw the SRT and HST trannies is in yours
the steering output goes right to the tank, while in HSTs, the steering
OUT provides the charge pump flow.

Excellent! Thanks, I had look in the same book and couldn't find it. I was hoping that it was a low pressure system. I have a project that I would like to do that needs no more than 1500 PSI.
