HYDRAULIC MOTOR CHECK OUT FOR MACHINES WITH LIVE HYDRAULICS
To check out a hydraulic motor the mechanic will need a pressure gauge capable of reading 3000 p.s.i. (207 bar), a Tee
fitting to install in the control valve, a plug fitting to install in the control or relief valve and a clean 5 gallon (19L) pail.
1) The following instructions are for machines with Live Hydraulics, for machines without Live Hydraulics
contact your local dealer or Bandit Industries.
2) In order to check out a hydraulic motor, it is necessary to mechanically stop the motor from turning
while under load. The hydraulic pump needs to be driven without turning the chipper disc/drum (Live
Hydraulics). Feed a reasonably large size log into the machine until it contacts the stationary
disc/drum. This should stall the hydraulic motor(s). It may also be necessary to apply down pressure
by operating the yoke control valve (if equipped).
3) With the feedwheel(s) mechanically locked as described, turn the engine off and keep the key in your
possession. If the hydraulic motor does not have a case drain, unhook the hose going from the
hydraulic motor back to the control valve at the valve, some machines will be equipped with a flow
divider between the hydraulic motor and the control valve. If the hydraulic motor has a case drain,
unhook the case drain hose that goes to the relief valve at the valve.
) Place the end of the hose in a clean gallon (19L) pail.
) Plug the open port of the control valve or main relief valve.
6) Unhook the other hose in the control valve and install a Tee fitting into the control valve and attach the
hose to the Tee fitting.
7) Install a pressure gauge in the other port in the Tee fitting to monitor hydraulic pressure.
8) Put the infeed control valve in the center position and start the engine.
9) Increase the engine speed slowly to full rpm.
10) Operate the infeed control valve to feed the log into the stationary disc/drum. If the feedwheel(s) try to
turn, apply down pressure by using the yoke control valve (if equipped).
11) Providing the pump and the relief are functioning properly, the pressure gauge should read the specified
main relief setting.
12) Observe the amount of hydraulic fluid coming from the hose into the pail. The amount of leakage
should not be more than about 1 g.p.m. (.8 L.p.m.) into the pail.
