assembly are described at the end of this section. A troubleshooting chart is also at the end of this section.
Description
A mechanically-operated shoe brake with a brake
drum fastened to the bevel gear shaft of the MDU
is used on all units.
An electrical cutout switch
operated by the linkage interrupts the power to the
drive motor when the brake is applied. The brake
and cutout switch, when properly adjusted, operate
simultaneously.
W/B60-80XT
A spring applies the brake when the steering handle
is in the vertical position or parallel to the floor. See
Figure 1. The steering handle has a cam that moves a
cam follower attached to a bellcrank. The bellcrank
is attached through linkage to a brake release arm
that will apply or release the brake when the steering
handle is moved. Movement of the brake release arm
compresses the spring to release the brake.
