Just again found this and know others were looking for the thread with pics.

Just a little heads up for some part numbers. The second picture in the set of 4 is the bottom of the leveling valve with the 2 O-rings and the HWH part numbers for the set is RAP6554. That is for a set that will do 6 valves, 12 total O-rings. Now when you look at the third picture that is the O-ring that no one sells, not even HWH, but I have a perfect match. It a Caterpillar O-ring part number 6V-7970 and as said before a Perfect Match. I just did mine and was looking for a match in All My o-ring kits. Just happen to have a Cat O-ring kit also and there it was.


My system 600 series is an older system so just a heads up the above numbers are for that series valves

I can't imagine why a good hydraulic repair shop would not have the "O-ring that no one sells" would not have one. For every o-ring that I have ever needed they have been able to provide me with one.
