4.7.5 Inspect the springs for distortion and check the free
height. If the free height of any spring is less than
the value shown on Table 7, the entire set of springs
must be replaced.
4.7.6 Reassemble the WCSB tensioner / brake assembly
by following the procedures in Section 4.9., beginning
with Section 4.9.20.
Caution
The cylinder, spring housing and end plate, should
not be re-assembled as a separate subassembly.
Improper assembly procedures may result in uneven
contact of the friction material with the disc (119),
resulting in low stopping torque.

Reaction Plate Bushing Replacement
(size 36 only)
4.8.1 Disassemble the WCSB tensioner / brake assembly
per Section 4.3.
4.8.2 Refer to Table 8 to determine if the reaction plate
bushings (54) require replacement.
4.8.3 Heat up the area around each bushing to soften the
Loctite
®
. Drive out the old bushings.
4.8.4 Clean the bores in the mating component, removing
any residual Loctite
®
.
4.8.5 Apply Loctite
®
#RC601, 635 or 680 to the bushing
O.D. and mating hole in the reaction plate using a
swab. Apply enough liquid to entirely fill the space
between the parts. Install the bushings by twisting
the bushing while pushing it down, until it is flush
with the casting surface. Inspect to see that a ring of
liquid adhesive is visible at the parting line. Reapply
Loctite if required. Allow the Loctite to cure for
15 minutes before moving the sub assembly.
