4.9.5.2 Place one support beam bushing (144) in each 2”
bore in the support beam (138).
4.9.5.3 Place one wear spacer retainer (141) over each beam
bushing (144).
Note: The support beam bushing (144) should be recessed slightly
from the surface of the wear spacer retainer (141). See Figure 1A
Section B.
4.9.6 With the wear plate facing up, lower the pressure
plate subassembly (116) over the clamp tubes so that
the position of the cooling water inlets & outlets are
at the 12, 3, 6 & 9 o’clock positions.
4.9.7 Pre-fill the grease channel in the friction disc sub-
assembly (7) splines with MOLUB-ALLOY® 936SF
grease, or equivalent, as shown on Figure 3.
4.9.8 Lower a friction disc subassembly (7) onto the
pressure plate wear surface. Center the friction disc
on the pressure plate (116).
4.9.9 Place a release spring (34) over every clamp tube. For
single disc tensioners, proceed to section 4.9.13.
4.9.10 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).
4.9.11 Assemble a release spring (34) over every clamp
tube, and lower a friction disc subassembly (7) onto
the reaction plate (30). Align the disc splines with
those in the previous disc assembled to ease
installation after assembly.
4.9.12 Repeat Sections 4.9.9 through 4.9.10 until all reaction
plates, friction discs and reaction springs are installed.
4.9.13 Lower the end plate subassembly (117) over the
clamp tubes, noting the orientation of the coolant
ports.
4.9.14 Wear Spacers & Beam Spacers
4.9.14.1 Assemble the wear spacers (29) over the studs (6)
that have clamp tubes (12) installed. Refer to Table
17 for the quantity required at this location (adjacent
to clamp tubes (12)) on each stud.
4.9.14.2 Assemble beam spacers (139) over the studs (6)
with support beams (138) installed. Refer to Table 17
for the quantity required at this location (adjacent to
support beam (138)) on each stud.
4.9.15 Assemble the friction discs (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, crosswise pattern. Screws in
friction disc should be installed from the center most
position in the 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.
4.9.16 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 sub-assemblies (7).
4.9.17 Assemble the stop plates (125) so that they rest
against support beam wear spacers (139).
Note: Each stop plate (125) installs over four studs (6). Locate
ends of stop plates (125) over support beam wear spacers (139).
Refer to Figure 8A. The support beam spacer (139) and the spacer
retainer (141) mount over the support beam (138) and studs (6).
The ends of each stop plate overlap the support beam spacer
as shown in Figure 8A. The small screw hole at one end of the
stop plate should line up with the middle screw hole in the spacer
retainer if the stop plates are properly assembled.
