Hi guys, new to the forum! We have an ancient JCB 20T excavator (820 series i believe). We are chasing the correct pressure settings for the MRV/Pressure relief valve. We've had the pump tested and came back fine, however were advised that the pressure settings are too high and need to be reset, however we don't have the optimum settings on hand. Being that the excavator is so old and we don't have the manual, where would be the best place to locate the pressure settings? i have the pump serial number PAA220808C522B2C 081027A/79 Any help you guys could provide would be greatly appreciated - thanks in advance!
