Hi, I have a B3350SU and can't find the part number, nor could the dealer for the shims for the loader pressure relief valve. I have a part number for the whole valve, YW23995100 and that is kit relief. I just need new shims to bring my pressure back up to what it should be.

Thanks

You will need to use the same shims that are common for the BX series. there are a number of suppliers that offer them. I'd suggest that you purchase or make a pressure tester. BXpanded and others offer the shims. You can look at the parts diagram for BX series to get the Kubota shim parts numbers.

31351-37970 110 SHIM 0.10mm
31351-37960 110 SHIM 0.20mm
31351-37950 110 SHIM 0.40mm

Bxpanded has a kit that includes the gauge and shims. https://www.bxpanded.com/pressure-tester

figure on approx 40 psi increase/0.1 of shim.
