EATON Airflex WSB 11210 WCSB3 Installation Operation and Maintenance E-CLCL-11001-E October 2013 10
WCSB3 Brakes
Note: The 12 customer supplied mounting screws need to be
Grade 8 and torqued to 70% yield load.
Note: To facilitate the mounting process, the friction disc
assemblies should be aligned to the gear and centered in the
tensioner. With the tensioner positioned with the mounting
flange/cylinder (112) facing down, lower the gear (28) slowly and
carefully into the splined bore of the friction disc assemblies
(7). Adjust the discs so that they are centered in the tensioner.
Apply and maintain an air pressure of 25 psig (1.7 Bar) to the
cylinder to release the brake and install the gear. Center the gear
then release the air pressure and remove the gear.
Danger
Use only the proper number and grade fasteners
shown in Table 4. Use of commercial grade (Grade
2) fasteners where Grade 8 fasteners are specified
may result in failure of the fasteners and a sudden
and drastic reduction in brake torque.
2.2.2 Ensure that the shaft is free of nicks or burrs and the
key fits properly in the shaft and gear.
2.2.3 Apply a light coat of anti-seizing compound to the
shaft and key. Tap the key into the shaft keyway.
2.2.4 Heat the gear uniformly to 250°F (121°C) to expand
the bore and ease assembly. Press the gear onto the
shaft, making sure that the dimension between the
gear and the tensioner mounting surface (“A”) is
maintained. See Figure 1 and Table 3. Allow the gear
to cool.
Caution
Do not allow the gear temperature to exceed 350
degree F (176 degree C). Overheating the gear will
adversely affect the hardness and wear life.
2.2.5 Apply a thin coat of MOLUB-ALLOY
®
936SF Heavy
grease to the gear teeth and slide the tensioner
assembly onto the gear. (Reference EATON/Airflex
Part Number 000153x1182).
Caution
Excessive lubricant may contaminate friction
material, resulting in erratic response or loss of
torque.
Caution
The use of anti-seize or bearing greases on the gear
splines may result in premature gear and disc spline
wear.
2.2.6 Pre-fill the grease channel in the friction disc splines
with MOLUB-ALLOY 936SF Heavy grease or
equivalent as shown in Figure 3. Try to maintain
the grease level at 1/8” (3mm) below the top of the
friction disc splines as shown in Figure 3. For
reference, the recommended grease is Eaton Part
Number 000153X1182.
Caution
Excessive lubricant in the grease channel and on the
gear teeth may contaminate friction disc material,
resulting in erratic response or loss of torque.
