WCSB tensioner / brake with ORB coolant ports
4.9 Assembly
Procedures
4.9.1 Position the mounting flange / cylinder (112) on a flat,
level surface, mounting face down. Note the location
of the cylinder inlets in the mounting flange as the
"6 o'Clock" position.
4.9.2 Lubricate the seals (21)(23)(114) with Molykote
®
55M O-ring lubricant, and install them into the seal
grooves on the piston (33). Note the orientation
of the seal lips, per Figure 21. Lubricate the seal
surfaces in the mounting flange / cylinder (112)
and evenly insert the piston into the mounting
flange / cylinder.
4.9.3 Install the studs (6) into the mounting flange (112).
The stud end with the shorter length of threads is
to be assembled into the mounting flange. Clean
the stud end to be assembled by applying Loctite
®
Loc-Quic
®
Primer Grade "T" to the threads. After
the threads have dried, apply Loctite
®
#271 to the
threads and assemble the stud until it bottoms in the
threaded hole in the mounting flange. Repeat for the
remaining studs.
Warning
Loctite
®
Primer "T" contains harmful vapors. Refer to
the product label for proper safety precautions
4.9.4 Install a clamp tube (12) over each stud.
4.9.5 With the wear plate facing up, lower the pressure
plate subassembly (116) over the clamp tubes,
noting the position of the water inlet in relation to
the ports in the mounting flange / cylinder. The inlet
ports should be as close as possible to the "6 o'clock"
position noted in 4.9.1.
4.9.6 Pre-fill the grease channel in the friction disc
subassembly (7) splines with MOLUB-ALLOY
®
936 SF Heavy grease, or equivalent, as shown
on Figure 3.
4.9.7 Lower a friction disc subassembly (7) onto the
pressure plate wear surface. Center the friction disc
on the pressure plate (116).
4.9.8 Place a release spring (34) over every clamp tube.
For single disc WCSB tensioner / brake assemblies,
proceed to Section 4.9.12.
4.9.9 On multiple disc assemblies, lower a reaction plate
subassembly (30) over the clamp tubes, noting the
position of the water inlet in relation to the ports in
the pressure plate (116).
4.9.10 Assemble a release spring (34) over every clamp
tube, and lower a friction disc subassembly (7) onto
the reaction plate. Align the disc splines with those
in the previous disc assembled to ease installation
after assembly.
4.9.11 Repeat Sections 4.9.9 through 4.9.10 until all reaction
plates, friction disc assemblies and reaction springs
are installed.
4.9.12 Lower the end plate subassembly (117) over the
clamp tubes, noting the orientation of the
water inlets.
4.9.13 Assemble the wear spacers (29) over the studs (6).
Refer to Table 11 for the quantity required at this
location (adjacent to clamp tubes (12)) on each stud.
