Only because the specified relief setting for the loader in the B1630/1640/1640A loader manual is 1450 psi when fitted to the B7200HSTD. Would you suggest leaving it at or a little higher than the tractor relief setting ?
Front loader for a B7200

Any idea why the relief pressure would be specified at 1450 psi in the B1630 loader manual ? Was there something different about this setup that meant this pressure didn't affect the 3PL pressure ? Just curious.
I will have to look at my msnuals.
The lower relief pressure absolutely lowers the 3pt lift capacity. I have no idea why that was done.The only readon I can think of is the loader was deemed too light for heavier loads.

Was there a front mounted pump version for power to the FEL on the B7200?
That is one way to get a separate (lower) rated FEL pressure that would not affect the three point hitch.

The B7200 outlet block relief specification is 2060 PSI.
The B7200 3pt lift is rated for 400 pounds max at the pins.
The B1630 loader used tractor hydraulics on all b7200 and B7100 models
Per the manual the loader relief cartridge was "not adjustable" and came preset at 1450 PSI. Yet there is a section on adjusting it later in the manual. The "tamper proof" cover is not hard to remove but it will self destruct and the adjusting screw will be left exposed. At one time replacement covers could be purchased from a dealer

I don't know how to adjust the tractor relief setting yet, but I think I'll leave it alone for now rather than risk leaks past old seals. 1800 psi instead of 2060 psi drops the lift capacity from 400 to 350 pounds. I'll look at the relief setting if this causes a problem.
When you refer to "at the pins", is that at the end of the lower arms, circled in red in the attached pic ?
