Section 5 Service Procedures
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

41. BEARING ALIGNMENT
NOTE: Severe out-of-balance loads can cause
misalignment of the flange-mounted bearings. Use
the following procedure to align and torque the
bearings.
a. Disconnect the power to the machine.
b. Tighten the rear bearing collar’s set screws to
hold the basket shaft in place. Do not torque
them at this time.
c. Loosen the front bearing collar’s set screws.
d. Connect power to the machine.
e. Start and run the machine in "medium" spin for
30 seconds to allow the bearing race to align.
f. Stop the machine and disconnect the power.
g. Apply loctite to the set screw threads.
h. Tighten the front bearing collar’s set screws
evenly by alternating between two of them until
they are snug. Finish tightening them with a
torque wrench until the correct torque is
achieved.
i. Loosen the rear bearing collar’s set screws.
j. Apply power to machine.
k. Start and run the machine in "medium" spin for
30 seconds to allow the bearing race to align.
l. Apply loctite to the set screw threads.
m. Tighten the rear bearing collar’s set screws
evenly by alternating between two of them until
they are snug. Finish tightening them with a
torque wrench until the correct torque is
achieved.
Bearing Troubleshooting Tips
a. "Knocking" sound during operation:
(1) Ensure that the mounting set screws are
adequately tightened and that the
dismounting set screws are in their original
position, protected by yellow plastic plugs.
(2) Ensure that the machine is secured to the
floor according to the manufacturer’s
instructions.
(3) If there is noticeable up and down play with
the basket, go to tip #3.
(4) If the noise persists, replace the bearing.
For warranty purposes, the old bearing
should be returned to the manufacturer for
a complete analysis.
b. Occasional slight noise during high speed spin:
(1) Pump a small amount of fresh grease into
the bearing unit.
(2) Check for basket play when the machine is
empty and not running. If there is basket
play, proceed to tip #3.
c. Basket play when the machine is empty and not
running:
(1) Further tighten each mounting set screw to
remove bearing clearance (up to 90 in-lbs is
allowable).
(2) If the basket play persists, dismount and
remount the bearings by following the steps
outlined in the instructions (without
unbolting the bearing housing from the
steel frame).
(3) If the basket play persists, replace the
bearing. For warranty purposes, the old
bearing should be returned to the
manufacturer for a complete analysis.
