Page: 24 / 42

5.5.2
Install w ear spacers (29) and clamp tubes (12)
over studs.
5.5.3
Place the first friction disc assembly onto the
mounting flange.
5.5.4
Place a release spring (34) over every other
clamp tube. Install w ear rings (58) and install
stop tubes (59) on every fourth stud w ithout
release springs and slide the reaction plate
assembly onto the clamp tubes. For single disc
elements proceed to para. 5.5.6.
5.5.5
The follow ing steps are for multi disc
elements:
5.5.5.1
Place friction disc assembly onto the
reaction plate.
5.5.5.2
Place a release spring (34) over every other
clamp tube. Install w ear rings (58) and install
stop tubes* * (59) or (80) on 3 equally spaced
studs w ithout release springs and slide the
reaction plate assembly onto the clamp tubes.
The stop tubes (80)* * on 324 WCB and
424 WCB units, must be installed in the
center or center two positions shown on
figure 5 & 6. These stop tubes are identi-
fied by a small hole drilled into the side.
Improper installation will cause the
element to bind.
* * NOTE: On 324 WCB and 424 WCB units
use Item (80) for the center set of stop tubes.
See Figure 5 and 6. These stop tubes are
identified by a small hole drilled into the side.
5.5.5.3
Repeat steps 5.5.5.1 and 5.5.5.2 for each
additional friction disc and reaction plate * * .
5.5.6
Slide the pressure plate and the cylinder/piston
assembly onto the studs. Lubricate the threads
on the end of the studs w ith 30 w t. oil or
anti-seizing compound and install the locknuts
(18) w ashers (17).
5.5.7
Tighten the locknuts, ONE TURN AT A TIME
and in an alternating ( crossw ise) pattern until
the cylinder is seated firmly against the clamp
tubes. Torque the locknuts to the appropriate
value. See Table 4.
The locknuts (18) must be tightened
gradually to prevent damage to the
tensioner components.
5.5.8
Reinstall the tensioner per 2.0.
5.6 Assembly of WCB’s without Stop
Tubes
Note: Item numbers (#) are show n
on Figure 1 & 3.
5.6.1
Place mounting flange (1) w ith studs (6)
installed on face w ith studs facing up.
5.6.2
Install w ear spacers (29) and clamp tubes (12)
over studs.
5.6.3
Place a friction disc assembly onto the
mounting flange.
5.6.4
Place a release spring (34) over every other
clamp tube. Slide the pressure plate (13)
onto the studs.
5.6.5
For multi disc elements, install a reaction plate
sub-assembly onto the clamp tube.
5.6.6
Place friction disc assembly onto the reaction
plate. Repeat the sequence until all friction
discs, and reaction plates are assembled.
5.6.7
Slide the pressure plate sub-assemblyand the
cylinder/piston assembly onto the studs.
Lubricate the threads on the end of the studs
w ith 30 w t. oil or anti-seizing compound and
install the locknuts (18) w ashers (17).
5.6.8
Tighten the locknuts, ONE TURN AT A TIME
and in an alternating ( crossw ise) pattern until
the cylinder is seated firmly against the clamp
tubes. Torque the locknuts to the appropriate
value. See Table 4.
The locknuts (18) must be tightened
gradually to prevent damage to the
tensioner components.
5.6.8
Reinstall the tensioner per 2.0.
