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.
