1. Left side traction pump
2. Hydraulic tube
4. Disconnect both ends of the hydraulic tube and remove the tube from the
machine.
5. Install one hydraulic test hose to the exposed fitting at the traction pump, and
a second test hose to the exposed fitting at the wheel motor.
6. Install a hydraulic tester to the exposed ends of the test hoses. Make sure
the tester is installed in the correct flow direction (toward the wheel motor)
and the tester flow control valve is fully open.
7. Install the rear wheel and lower the machine to the ground.
8. Attach a heavy chain to the rear of the machine frame and an immovable
object to prevent the machine from moving during testing. Remove as much
slack in the chain as possible.
9. Disengage the parking brake.
Note: The engine will stop if the brake is engaged and a traction control lever
is moved out of the N
10. Start the engine and run it at low-idle speed. Correct any hydraulic fluid leaks
at the test connections before continuing the test.
11. Set the throttle to the full speed (3,575 to 3,725 RPM). Verify the engine
RPM with a non-contact tachometer.
12. Make sure hydraulic fluid is at normal operating temperature by operating the
machine for approximately 5 minutes.
Use extreme caution when performing the test. The rear wheel being
tested will be trying to move the machine forward.
