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 f or 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 hydraulic oil is at normal operating tem-
perature by operating the machine under load for
approximately ten (10) minutes.
2. Make sure that traction pedal is adjusted to the neu-
tral position (see Traction Unit Operator’s Manual).
3. Parkmachineonalevelsurfacewiththecuttingunits

the parking brake.
