Traction Circuit – Wheel Motor Efficiency (right side test shown)
Wheel motor efficiency is the second in a series of tests recommended to
determine traction circuit performance. Too much hydraulic fluid flow through a
single stationary wheel motor under load indicates an internal leak in the wheel
motor. A worn wheel motor is less efficient. Eventually, enough fluid by−pass will
cause the wheel motor to stall under heavy load conditions. Continued operation
can generate excessive heat, cause damage to seals and other components in
the hydraulic system, and affect overall machine performance.
