Procedure for Front Wheel Motor Efficiency Test
NOTE: Over a period of time, a wheel motor can wear
internally. A worn motor may by- pass oil causing the
motor to be less efficient. Eventually, enough oil loss will
cause the wheel motor to stall under heavy load condi-
tions. Continued operation with a worn, inefficient motor
can generate excessive heat, cause damage to seals
and other components in the hydraulic system and af-
fect overall machine performance.
IMPORTANT: Refer to Traction Circuit Component
Failure in the General Information section for infor-
mation regarding the importance of removing con -
tamination from the traction circuit.
NOTE: This test procedure includes steps to test both
front wheel efficiency together before testing individual
wheel motors.
1. Make sure that traction pedal is adjusted to the neu-
tral position (see Traction Unit Operator’s Manual).
2. Drive machine to an open area. Park machine on a
level surface with the cutting units lowered and disen-
gaged. Make sure engine is off.
3. Read Precautions For Hydraulic Testing in this sec-
tion.
CAUTION
Before opening hydraulic system, operate all hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving Hydraulic System Pressure in the Gen-
eral Information section of this chapter.
4. Attach a heavy chain to the rear of the machine frame
and an immovable object to prevent the machine from
moving during testing.
5. Chock front wheels to prevent wheel rotation.
