SCHEMATIC SHOWN
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.
