4.8.1 Disassemble per section 4.3.
4.8.2 Refer to Table 13 to determine if the reaction plate
bushings (54), in Figure 14, 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
®
.
4.8.4.1 Refer to the wear limits in Table 13 to determine if
the original reaction hole is within specification.
Inspect the ID of the reaction hole before installation
of the new bushing (54). If the reaction hole is oblong
or measures different from the wear specification
(Table 13) then consult the factory.
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.
Caution
The bushing (54) shall be held in place so it is cen-
tered in the reaction hole. Do not allow the bushing
to protrude beyond the surface of the reaction
plate, pressure plate or end plate during installation.
Allow the Loctite to cure for 15 minutes before
moving the sub-assembly.
4.8.6 Assemble the tensioner per section 4.9, as required.

Assembly Procedures
Note: Friction discs (7) and water jackets (reaction plates (30),
pressure plate (116) and end plate (117) should be assembled as
sub-assemblies per the appropriate maintenance procedures prior
to final assembly of the tensioner.
4.9.1 Position the mounting flange/cylinder (112) on a flat,
level surface, mounting face down.
4.9.2 Lubricate the seals (21), (23) and (114) with Molykote
O-ring lubricant, and install them into the seal grooves
on the piston (33). Note the orientation of the
seal lips, per Figure 13. Lubricate the seal surfaces
in the mounting flange /cylinder (112) and evenly
insert the piston into the mounting flange/cylinder.
