Basket Pulley, Bearing Housing, Water Seals
and Tub Back
The cast iron basket pulley is retained by a bolt, locking washer and a flat washer.
Removal
Step 1: Insert a large screw driver or punch through a spoke in the
pulley into the bearing housing support. This keeps the pulley
from turning.
Step 2: Remove the retaining bolt, lockwasher and flat washer and
reinstall just the bolt
Step 3: Use a puller to remove the pulley from the shaft. Watch for
tolerance ring.
Reassembly
Step 1: Make sure that the tolerance ring is in place inside the pulley.
Step 2: The shoulder inside the pulley that holds the tolerance ring should face the back of the
washer when installed correctly.
Step 3: Use a stack of flat washers and a longer bolt to press the pulley onto the basket shaft.
Step 4: Reinstall the retaining bolt, lock washer and flat washer. The shaft end bolt with washer
should be installed with a torque value listed in charts in this manual.
Removal of Bearing Housing From Basket Shaft,
Bearings and Water Seals
Step 1: To remove the tub back assembly, the 6 bolts attaching it to
the bearing housing must be removed.
Step 2: Remove water seals from the seal mounting plate on the
cylinder shaft. These are removed with your fingers.
Step 3: The retaining ring next to the front bearing must also be
removed.
Step 4: The bearings are pressed into the housing and must be
pressed back out.
Reinstallation onto Basket Shaft
Step 1: Carefully set the assembly over the shaft engaging the bearings and bearing spacer.
Step 2: The tolerance ring that fits inside the pulley should be placed in position (see Basket Pulley
Reassembly for correct positioning).
Step 3: The pulley should then be started onto the shaft. A stack of flat washers and a longer pulley
bolt will be required to pull the basket shaft through the bearings and pulley.
Step 4: Install the shaft end bolt with washers and torque to specifications in Bolt Torque Chart.
Step 5: See Tub Back, Bearing and Cylinder Assembly for installation of complete assembly back into
washer.

Reassembly
Step 1: When installing new bearings into a bearing housing, first press
the front (large) bearing into the housing until it bottoms. With
the bearing spacer in place, press the rear bearing in until the
spacer is snug between the two bearings. Be sure and reinstall
the retaining ring in front of the front bearing (see picture).
Step 2: The tub back assembly should be reattached to the bearing
housing with the 6 mounting bolts and torqued according to the
torque chart. Note: The bead of silicone that seals each
bolt to the tub back. This must be cleaned and replaced
upon reassembly (see picture).
If the 6 support assemblies have been removed from the bearing
housing, the 6 rear bearing housing bolts should be torqued
according to the chart also.
Step 3: The primary and secondary seals that mount on the sealing ring
may be slid over the shaft and seated on the metal sealing ring.
In the unlikely event that the metal ring that mounts these sealing
rings were to be damaged or moved, a new one would need to
be pressed on.The ring must be pushed against the stop on the
shaft. Before installing the new sealing ring, a bead of silicone
should be put on the basket shaft (see picture). After installing
the seals, lubricate the faces of the seals with silicone grease (see
picture).

Drive Motor Removal

Step 1: Remove the drive belt as explained in previous instructions.
Step 2: Remove the tension spring and bracket.
Step 3: Disconnect the motor wires in the control area at the top of the machine. The motor wire retaining
clamp should be removed and reused. There is a diagram showing where each motor wire plugs
in so there is no need to mark them.
Step 4: Loosen the set screws on the motor support shaft.
Step 5: Remove the retaining bolt from the front of the support shaft.
Step 6: Remove the motor support shaft.
Step 7: Lift motor out of machine. Note: On larger washers it is advisable to put a board under the motor
and slide it out rather than lifting it.
