Procedure for 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
motortobelessefficient.Eventually,enoughoillosswill
cause t he wheel motor to stall under heavy load condi-
tions.Continuedoperationwith aworn,inefficientmotor

and other components in the hydraulic system and af-
fect overall machine performance.
1. Make sure hydraulic oil is at normal operating tem-
peraturebyoperatingthemachineforapproximatelyten
(10) minutes. Make sure the hydraulic tank is full.
2. Parkmachineonalevelsurfacewiththecuttingunits
lowered and off. Make sure engine is off.
CAUTION
Before continuing further, read and become f a-
miliar with Precautions for Hydraulic Testing.
3. Make sure that traction pedal is adjusted to the neu-
tral position (see Traction Unit Operator ’s Manual).
