WCSB tensioner / brake with ORB coolant ports
Figure 8
4.2.2.5 While supporting the weight of the cylinder / spring
housing/pressure plate assembly, tighten the
locknuts (18) and sleeve nuts (106) if applicable ONE
TURN AT A TIME and in a crosswise pattern, until
the spring housing is seated tightly against the clamp
tubes. Torque the locknuts and sleeve nuts to the
appropriate value. See Table 2.
Caution
The locknuts (18) and sleeve nuts (106) must
be tightened gradually and evenly to prevent
damage to the WCSB tensioner / brake
assembly components.
4.2.2.6 Reinstall the support bracket if required. Secure
the bracket onto the sleeve nuts using flat washers
(17) and locknuts (18). Tighten the locknuts to the
value listed in Table 2. Shim the base of the support
bracket as required. Install and tighten fasteners as
required to secure the bracket into position.
Warning
Ensure that the support bracket does not interfere
with or bind on the cylinder (19). Interferences
could prevent the brake from properly engaging or
releasing.
4.2.2.7 Restore any piping or covers removed prior to
operating the WCSB tensioner / brake assembly.
4.3 Disassembly
Procedures
Warning
Ensure that the machinery is and will remain in a safe
position prior to loosening fasteners or removing the
WCSB tensioner / brake assembly.
4.3.1 Disconnect the air supply lines and water lines from
the WCSB tensioner / brake assembly.
4.3.2 Remove the fasteners that secure the brake and
support bracket to the mounting structure.
4.3.3 Using soft slings, rig the WCSB tensioner / brake
assembly and slide the WCSB tensioner / brake
assembly off of the gear. Avoid placing slings or
straps directly on the release springs (34).
4.3.4 Transport the WCSB tensioner / brake assembly to
a clean working area and position the unit on a flat
surface with the mounting flange (112) facing down.
4.3.5 If the gear (28) requires replacement, remove it from
the shaft with a portable jack, using the threaded
holes in the end of the gear for puller holes. Heating
may be required to ease removal. Replace the gear
and install per Section 2.2.
4.3.6 Match-mark the mounting flange (112), pressure plate
(116), reaction plates (30), end plate (117), pressure
plate (13), spring housing (16), and cylinder (19) to
one another prior to disassembly to adequately show
the proper orientation of components to one another.
4.3.7 Loosen the locknuts (18) or sleeve nuts (106) ONE
TURN AT A TIME and in sequence until the release
spring force is relieved.
Caution
The locknuts (18) must not be loosened unless the
screws (20) are in place retaining brake spring tension.
4.3.8 Lift the cylinder, spring housing, and pressure plate
off of the studs as an assembly. Set the assembly
aside on a clean, level area, making sure to avoid
damaging the friction material surface.
4.3.9 Continue removing the remaining components if
required.
4.3.10 Inspect all components using the wear limits in
Table 8 as a reference.
4.3.11 For friction material replacement refer to Section 4.4.
4.3.12 For wear plate replacement refer to Section 4.5.
4.3.13 For seal replacement refer to Section 4.6.
4.3.14 For spring replacement refer to Section 4.7.
4.3.15 Assemble the tensioner per Section 4.9.
