24.3. If the performance of the right side drive system
is suspect, pay particular attention to the belt
and tensioner. There is more belt wrap on the
left pump pulley than the right because the ten-
sioner is on the left side of the frame.
See Figure 24.3.
24.4. Observe normal hydraulic precautions:
• Allow the engine and drive system to cool before
disconnecting any fittings that may expose the
technician to hydraulic fluid.
• If the hydraulic system or gauge set develop any
leaks in the course of operation or testing: dis-
continue operation immediately, identify and
repair the leak.
• Relieve pressure from the system before discon-
necting any components or fittings: with the
engine and brake off, stroke the controls through
their full range of motion.
• Clean the area surrounding any components or
fittings to be disconnected to prevent contamina-
tion of the hydraulic fluid.
• Clean-up any spilled fluid promptly to prevent
accidents.
• Wear eye protection while working on hydraulic
systems.
24.5. Lift and safely support the rear of the mower.

24.6. Remove the wheels using a 3/4” wrench.
See Figure 24.6.
24.7. The gauge set should be connected so that the
fluid enters the gauge set from the pressure
gauge side and exits through the flow meter
side. There are a variety of way to accomplish
this. Bear in mind that:
• Valid tests can be made in the forward or
reverse direction.
• Valid tests can be performed with or without the
wheel motor in the hydraulic circuit.
• Disconnecting just one hydraulic line from the
wheel motor, and installing the gauge set in
series with the motor is slightly less work than
disconnecting both lines
• Fluid flow: In forward motion, fluid enters the
wheel motor through the upper “B” port on the
motor and exits through the lower “A” port.
• Either port may be used:
The gauge set would be connected with the flow
meter nearest the wheel motor if the “B” port is
used and the test is made with forward wheel
motion.
The gauge set would be connected with the
pressure gauge nearest the wheel motor if the
“A” port is used and the test is made with for-
ward wheel motion.
24.8. Configure the test kit for the intended installa-
tion, with fittings finger-tight to facilitate adjust-
ment. Keep it within arm’s reach along with any
wrenches needed to tighten the fittings. Set-up
and wrench sizes may vary.
