Case-IH 2200 Loader relief valve shims

[BruceH]

I have a 485 MFD tractor with a 2200 loader, the hydraulic pressure appears to be low, there is only 400 hours on the machine. I plan on checking the actual pressure but wanted to have some shims available if it is below spec.

The shims appear to be an obsolete part.

The part number is D25844 or 380365R1

Some internet searching came up with a possible size as follows ID 45.5mm OD 64mm Thickness .25mm

Can anyone confirm these dimensions before I take the relief valve apart, the tractor is located about a 6hr drive from where I live and there is no dealer within 2hrs of the tractors location.

The info in my first post about the size of this shim is incorrect!

In case anyone else finds this thread looking for information about the D25844 shims, I was able to find several new ones at a dealer, here are the specifications for this OEM shim. It is a very simple disc shim which could probably be cut from any shim stock material using a good pair of sheet metal snips.
The thickness of D25844 is .011" (0.28mm); The OD is .690" (17.53mm) there is no hole in it, just a simple disc!
The material is steel, possibly spring steel as it is very stiff
