WCSB tensioner / brake with ORB coolant ports
4.9.14 Assemble the friction discs or blocks (118) to the
end plate subassembly (117) and pressure plate (13)
per the following: Position the friction material to
align the screw holes. Apply Loctite
®
#262 to the
screw threads and tighten the screws (121) to
20 ft-lb. (27 nm) Install the screws in an even,
cross- wise pattern. Screws in friction blocks should
be installed from the centermost position inthe
block, then progressing towards the outer edges
of the block. One at a time, install and torque each
screw immediately after application of Loctite
®,
then
proceed to the next screw.
Warning
Loctite
®
may cure prior to properly tightening the
screw if not tightened to the proper torque value
immediately after installation.
Caution
Use only Airflex-supplied screws.
Caution
Loctite
®
#262 must be shaken prior to application.
Caution
Loctite
®
#262 may irritate sensitive skin. Refer to the
product label for proper safety precautions.
4.9.15 Lower the disc (119) onto the friction material on
the end plate subassembly (117), centering it on the
friction blocks or disc. Align the splines with those in
the tensioner friction disc subassemblies (7).
4.9.16 Assemble the stop plates (125) over adjoining pairs of
studs so that they rest against the end plate or
wear spacers.
4.9.17 Install the remaining wear spacers (29) over the
studs. One spacer should be placed over each stud.
See Figure 1
4.9.18 Slide the clamp tubes (124) over the studs.
4.9.19 Lower the pressure plate (13) over the clamp tubes
(124), resting the friction material face against the
disc (119).
4.9.20 Install the springs in a symmetrical pattern on the
pressure plate subassembly (13), distributing them as
evenly as possible. Locate the springs over bosses
or in the spring pockets in the pressure plate, as
shown in Figure 18 for 24WCSB tensioner / brake
assemblies, Figure 19 for 36WCSB tensioner / brake
assemblies and Figure 20 for 48WCSB tensioner /
brake assemblies. If applicable, position the spring
retainers (53) on top of the springs to hold the springs
into position.
4.9.21 Lower the spring housing and cylinder over the
springs and spring retainers, if applicable, aligning
the match marks made during disassembly.
Be sure to not overlap spring retainers such that
they interfere with the ribs in the spring housing (16)
when assembled.
Caution
Interference of the spring retainers with the casted
ribs in the spring housing will damage the spring
retainers and may prevent proper positioning of the
springs.
4.9.22 Lubricate the ends of the studs (6) with 30 weight
oil or an anti-seize compound, and assemble the
locknuts (18) and flat washers (17) onto the studs.
Tighten the nuts in an even crosswise pattern ONE
TURN AT A TIME to evenly compress the springs.
Tighten the nuts to the final tightening torque
listed on Table 2
Note: If sleeve nuts (106) are used to accommodate a support
bracket, install the sleeve nuts onto the studs in place of the
locknuts at or near the "6 o'clock" position, tightening them as
required.
4.9.23 Lubricate the seals (21)(23) with Molykote
®
55M O-ring lubricant, and install them into the
seal grooves on the spring housing (16). Note the
orientation of the seal lips, per Figure 16.
4.9.24 Lubricate the seal surfaces in the mounting cylinder
(19) and lower the cylinder onto the spring housing.
Orient the cylinder so that the Eaton logo is near the
"12 o'clock" position, in-line with the water outlets.
4.9.25 Position the spacer tubes (27) in-line with the bolt
holes in the cylinder, and install the hex head screws
(20) and lock washers (17). Tighten the screws in a
crosswise pattern ONE TURN AT A TIME until the
spacer tubes are clamped between the cylinder and
pressure plate. Make sure the cylinder slides over the
seals properly, to avoid damaging the seal lips.
