proper safety precautions.
4.1.3.4
Using lifting equipment, remove the pressure
plate assembly (13) and carefully place it on
a suitable work surface with the wear plate
(3) facing up. Do not damage the wear plate.
4.1.3.5
Remove the friction disc assembly, the
reaction plate assembly (30), release springs
(34), stop tubes (59) and wear ring (47) from
each stud and set aside Repeat for three and
four disc units.
4.1.3.6
Remove the clamp tubes (12) and one wear
spacer (29) from each stud. Reinstall the
clamp tubes, set aside the removed wear
spacers and ONLY one wear ring(s) (47) from
each stop tube that was removed.
4.1.3.7
Slide the friction disc assembly onto the gear.
4.1.3.8
Place a release spring over every other
clamp tube. Install required number of wear
rings (47) and install one stop tube on every
fourth stud without release springs and slide
the reaction plate assembly onto the clamp
tubes.
NOTE: Quantity of wear rings re-installed at
each location should be same as quantity of
wear spacers installed.
4.1.3.9
For multi-disc units, repeat steps 4.1.3.7 and
4.1.3.8 for each additional friction disc and
reaction plate .
4.1.3.10
Slide the pressure plate and the cylinder/
piston assembly onto the studs. Lubricate
the threads on the end of the studs with 30
wt. oil or anti-seizing compound and install
the washers (17), wear spacers (29) and the
locknuts (18) removed in 4.1.3.6.
4.1.3.11
The wear spacers are “stored” under the
locknuts and washers for use after replacing
the friction discs. See Figure 9.
4.1.3.12
Discard un-used wear rings. Use new wear
rings when replacing friction discs.
4.1.4
While supporting the weight of the cylinder/
piston assembly, tighten the locknuts, ONE
TURN AT A TIME and in an alternating
(crosswise) pattern until the cylinder is
seated firmly against the clamp tubes.
Torque the locknuts to the appropriate
value. See Table 5.
The locknuts (18) must be tightened
gradually to prevent damage to the
tensioner components.
4.1.5
Check that clearance exists between friction
discs and wear plates.
4.1.6
Reinstall air and coolant lines per 2.0.
4.2
Removal of WCB
4.2.1
Disconnect the air and water supply lines.
4.2.2
Using lifting straps, rig the unit and remove
the mounting screws from the mounting
flange (1).
4.2.3
Slide the WCB off of the gear (28) and
transport it to a clean working area placing
the WCB on its mounting flange, studs (6)
facing up.
