WHEEL MOTOR EFFICIENCY TEST FOR
RIGHT FRONT WHEEL MOTOR SHOWN
NOTE:
Over a period of time, a wheel motor can wear
internally. A worn motor may by--pass oil to its case drain
causing the motor to be less efficient. Eventually,
enough oil loss will cause the wheel motor to stall under
heavy load conditions. Continued operation with a worn,
inefficient motor can generate excessive heat, cause
damage to seals and other components in the hydraulic
system and affect overall machine performance.
Procedure for Wheel Motor Efficiency Test:
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately ten
(10) minutes. Make sure the hydraulic tank is full.
2. Park machine on a level surface with the cutting units
lowered and off. Make sure engine is off. Make sure the
hydraulic tank is full.
