EATON WSB11206 WCSB Tensioner / Brake with ORB Coolant Ports Installation, Operation and Maintenance Manual E-CLCL-II009-E August 2015 17
4.1 Wear Limits
Warning
Periodically examine the WCSB tensioner / brake
assembly for wear of friction material, discs and wear
plates. Failure to perform this examination will result
in excessive wear, a significant reduction in torque,
and may result in personal injury and / or damage to
the machinery.
4.1.1 Wear limits for the WCSB tensioner / brake
assembly's components are shown in Table 8. If
any wear limit has been reached or exceeded, that
component must be repaired or replaced.
4.2 Wear Adjustment
Wear adjustment is periodically required as the
friction material and mating surfaces wear.
Wear adjustment reduces the running clearances
between these surfaces to help maintain the holding
force of the brake (for the spring applied feature),
and to maintain the responsiveness of the brake by
limiting the travel of components. Mechanical limits
within the brake design require that the brake be
adjusted when the adjustment points listed in
Table 8 have been reached.
Warning
Failure to perform adjustments when required
may result in loss of adequate brake torque and
potential injury to personnel or damage to
equipment. Be certain to inspect the brake
periodically to evaluate for wear, and adjust
as necessary.
4.2.1 WCSB tensioner / brake assembly Inspection and
Evaluation
To determine when WCSB tensioner / brake
assembly adjustment is required, the WCSB
tensioner / brake assembly should be evaluated as
follows:
4.2.1.1 Visually inspect for friction material wear.
The friction material is fully worn when the wear has
reached the bottom of the wear groove or notch as
shown in Figure 6.
Note: Friction blocks for the air cooled brake in 48WCSB
tensioner / brake assemblies have a step on the outer edge of the
friction material rather than a wear groove. The material is fully
worn when wear has reached the step on the outer edge of the
friction material. See Figure 6a.
Note: If fully worn replace the material and evaluate the condi-
tion of the mating wear surface.
Note: If the wear limits of any of the friction discs or blocks have
not been reached, determine if brake adjustment is required by
proceeding to the next steps.
