Being on the MOC for years ... I think Dale has been on here for years as well. We've conversed many years ago about shear bolts for the balance shaft on the bigger hydraulic slides. He has good advice on the selector valves, but I never figured out other than $$$ why Keystone makes you go out side and turn shut-off valves. I did this mod back in 2007 on my 2980 and transferred it to my 3150 when we traded. The Parker valve numbers are obsolete, but you can source replacements in today's market. They are really just blocking valves with free reverse flow. All I do is flip a switch to stop slide movement.
