Fired up the grader today testing the switch wires. Everything was perfect. No mystery smoke which is a good thing. While is was on the stand I decided to test the rears and attempt synchronization. The back hydro is not moving. Not sure what that is all about yet. I purchased the rear from two different places as pieces so I never saw them run. Only one of the rears has automatic relief valves so I switched those to the rear hydro because the engine sits over them and there is no good way to use manual valves there. The front rear that originally had those valves now has the manual valves and operates as it should. I think I will move the manual valves back to the rear just to see if that makes any difference.
On a different note I had only planned to check the wiring and makes sure the engine was running properly but when everything went along without a hitch I decided to engage the belt tightener just to test the rears. My brain fog apparently had not cleared yet as I forgot that I had the return fluid line removed from the spool valves. In case anyone needs to know the charge pump will produce enough pressure to spray about 15 feet across your garage. At least I feel like the system is flushed pretty well now.
