Seal Adjustment - Trane CLCH-SVX02C-EN Installation Operation & Maintenance

18. Adjust the seals according to the
procedure in "Seal Adjustment"
on page 17.
19. Rotate the wheel in a clockwise
direction to confirm that it rotates
freely with slight drag on seals.
20. Re-install the bearing locking
collar.
21. Rotate the collar by hand in the
direction of wheel rotation.
22. Lock the collar in position by
tapping the drift pin hole with a
hammer and drift.
23. Secure the collar in position by
tightening the set screw.
24. Re-install the bearing access
cover.
25. Apply power to the wheel and
ensure that the wheel rotates
freely without interference.
For sizes 3 to 8
Bearing removal is not required on
slide-out cassettes, unit sizes 3 to 8.
These belts may be replaced by
temporarily dismounting and
rotating the pulley side bearing
beam to allow the new belt to be
installed on the wheel rim.
1. Disconnect electrical power to
the energy wheel.
2. Remove the access panel.
3. Disconnect all controls wiring.
4. Slide the entire cassette assembly
out of the module.
5. Loosen the two set screws on the
wheel support beam bearings,
one on each side of wheel.
6. Remove the belt from the pulley
and temporarily position it
around the rim.
7. Remove the pulley side wheel
support beam with the bearing.

Service and Repair
8. Pull the wheel with the shaft
straight out of the motor side
wheel support beam and bearing
(see Figure 17). Do not
disassemble the bearings from
the beam unless they require
replacement. Handle the wheel
with care to avoid distorting the
wheel.

assembly
9. Reverse the removal procedure to
re-install. Check to ensure that the
wheel remains in the center of the
seal plate opening.
Figure 18. To adjust seal, loosen screws, back seals away from wheel surface.
Seal seen from bottom section.

Seal Adjustment

1. Loosen the diameter seal
adjustment screws and back the
seals away from the wheel
surface (see Figure 18).
2. Rotate the wheel clockwise until
two opposing spokes are hidden
behind the bearing support beam.
3. Using a folded piece of paper as a
feeler gauge, position the paper
between the wheel surface and
the diameter seals.
4. Adjust the seals toward the wheel
surface until slight friction on the
paper feeler gauge is felt when
the gauge is moved along the
length of the spoke.
5. Check the adjustment through a
full rotation of the wheel.
6. Retighten the adjusting screws
and recheck the clearance with
the paper feeler gauge.
