WCSB3 Brakes
Note: If it is found that no wear spacers (29) exist between the
clamp tube (12) and stop plate (125) before adjustment is
attempted, all wear adjustments have been previously performed
in the water-cooled section of the brake, and brake overhaul is
required.
(i)
If the gap measured for gap X is equal to or less than
the adjust value, wear adjustment is required. Adjust
the brake per the procedures listed in section 4.2.2.
If it is found that no wear spacers (29) exist between
the clamp tube (124) and stop plate (125), all wear
adjustments have been previously performed in the
air-cooled section of the brake and replacement of the
friction discs (118) and disc (119) may be required.
Remove the brake from service and evaluate the
condition of those components, using Table 14 as a
reference.
Warning
If wear adjustment is not made, the piston may
extend out of the mounting flange/cylinder (112)
beyond an acceptable operating range, resulting in
loss of torque and/or seal (21, 23 and/or 114) damage.
If the “Y” or “Z” dimensions have been reached or
any of the friction discs are worn to the bottom of
the wear groove, the tensioner should be taken out of
service and rebuilt with new components as required.
4.2.2 Adjustment Procedure for Water Cooled
Tensioner
Wear adjustment can be conducted without full
disassembly of the WCSB3 tensioner. Wear
adjustment of the water cooled tensioner is
accomplished by removing the support beam wear
spacers (139) and the wear adjustment spacers
(29). The wear adjustment spacers are slotted to
allow for easy removal with a chisel. The support
beam wear spacers are slotted to allow for
positioning with alignment pins (hex screw, nut
and washer 142, 143 & 145) and easy removal when
the alignment pins are loosened (See Figure 1A,
Section ‘B’ and Figure 1C, Section ‘Z-Z’).
