when going to move or pull a ztr- how do you 'release' the pumps?? just take belt off? thanks- Geno
There is a dump (release) valve on most hydro pumps that will release pressure for moving a non-running unit. Without any numbers or pump brand posted it could be anywhere on the pump.
Look on the side of the pump. There is generally a bypass valve. Just use a wrench and open it up a few turns.
thanks- learning as I go with these hydro things. Geno
What is required once the mower is fixed and ready to be ran again? Do you have to do anything after you tighten up the release valve, or is it good to go then? I'm wandering if you have to purge air or anything.
As long as you haven't opened the hydraulic system, just close the bypass valves and you're ready to go.
Most dump valves are 5/8 with a hole through the nut, this is the best way to describe without pics. Do not remove them all the way, just loose enough to get the machine to roll, after moving always tighten the dump valve.
