I just realized how important this site is....So I joined....Have been playing with Cubs for 30 odd years and now realize how much I do not know....To the point,I have several leaky Dump Valves which I intend to redo as I have the equipment....I always considered that the main purpose of these valves was to bypass the motor and allow the wheels to turn when pushed or on an extreme incline but I was mistaken.....They are in there to maintain the high pressure circuits at a maximum of 3500 PSI and prevent physical damage to the aluminum case....It all makes sense to me now that I know their their real purpose....Used to roll the tractor without engine power is a bonus feature of the overall design and not the intended use...Something else I found is that sealing the vent hole in the valve top(weld up) will not work....Yesterday I tried it on my 782 since I do not care if it will roll or not....Mig'd both them closed and installed them.....No power to the diff in either direction......Ground off the welds and away she went....Thanks for your patience
