Measure gaps between the components at
positions W, X, Y-1, and if applicable, Y-2, and Y-3.
See Figures 6, and 6a for the location of those
gap positions.
For reference:
The W-gap is the measurement between the end
plate (117) and the stop plates (125) and is used to
determine when adjustment of the water-cooled
section of the WCSB tensioner / brake assembly
is required. This gap will increase as the WCSB
tensioner / brake assembly wears.
The X-gap is the measurement between the end
plate (117) and the pressure plate sub-assembly (13)
and is used to deter- mine when adjustment of the
air-cooled section of the WCSB tensioner / brake
assembly is required. This gap will decrease as the
WCSB tensioner / brake assembly wears.
The Y gaps are measurements between the various
wear plate sub-assemblies and are used to help
evaluate the wear of the water- cooled friction discs
and wear plates. These gaps will decrease as the
WCSB tensioner / brake assembly wears.
The wear limit for each of the Y gaps is the same
for Y-1, Y-2 or Y-3.
Y-1 is the measurement between the mounting
flange (116) and the reaction plate (30).
Y-2 is the measurement between the reaction plate
(30) and the adjacent reaction plate. The Y-2 gap is
found only on WCSB tensioner / brake assembly that
have three or more ‘water- cooled’ discs.
Y-3 is the measurement between the
reaction plate (30) and the end plate (117).
e)
Record the W, X, Y-1, Y-2, and Y-3 values measured
for each of the gaps, and compare them against the
values listed in Table 9.
f)
If the value measured for any Y gap (Y-1, Y-2, Y3)
is equal to or less than the Y min value, the WCSB
tensioner / brake assembly should be removed from
service and repaired with new wear components.
g)
If the value measured for all Y gaps (Y-1, Y-2 or Y-3) is
greater than the Y min value, proceed to evaluate the
measurement for gap W as follows:
h)
If the measurement for gap W is equal to or greater
that the Wadjust value shown on Table 8, wear
adjustment is required. Adjust the WCSB tensioner /
brake assembly per the procedures listed in section
4.2.2. 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 WCSB tensioner / brake assembly and
brake overhaul is required.
i)
If the gap measured for gap X is equal to or less
than the Xadjust value, wear adjustment is required.
Adjust the WCSB tensioner / brake assembly 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
WCSB tensioner / brake assembly from service and
evaluate the condition of those components, using
Table 9 as a reference.
