Drive Pulley and Cam Removal

The Drive Pulley and Cam are located below the Brake
assembly on the drive shaft. A Washer and Retaining
Ring secure the Pulley and Cam on the drive shaft. A
plastic Dust Cap snaps to the underside of the Pulley to
keep the Cam surfaces clean. These components can
be removed by tipping the Washer back to access
bottom side of unit.
1. Disconnect power supply to unit.
2. Remove (pry off) Dust Cap from under side of pulley.
3. Remove Retaining Ring and Washer from end of
drive shaft.
4. Firmly pull Lower Cam off of the drive shaft splines,
then slide the other parts off of the shaft.
Models are equipped with a plastic Drive Pulley which has
the upper Cam molded onto the bottom of the Hub. The
purpose of the Pulley and Cam arrangement is to drive the
Clutch assembly during the agitate and spin cycle, and to
disengage the Brake assembly during the spin cycle.

WARNING
To avoid risk of electrical shock, personal injury or death,
disconnect power to unit before servicing.
The Drive Pulley slips over the drive shaft and rests
against a series of Washers, a Thrust Bearing, and a
large washer type Spacer. The Spacer locates against
the bottom of the Brake Rotor and Lining assembly. The
Lower Cam slips over the end of the drive shaft where
splines formed in the Cam engage with mating splines
on the drive shaft end. This imparts a direct drive from
the Cam to the drive shaft. A shoulder molded on the
bottom of the Pulley hub engages "dogs" formed on the
sides of the Lower Cam, and will drive it and the drive
shaft in either direction.
