EATON WSB11206 WCSB Tensioner / Brake with ORB Coolant Ports Installation, Operation and Maintenance Manual E-CLCL-II009-E August 201526WCSB tensioner / brake with ORB coolant ports12162395810116141571413Figure 154.5.10 After completion of the assembly, each water cavityshould be checked for leaks.4.5.11 Using lifting straps, suspend each assembly withthe water outlet port at the 12 o'clock position.Connect a water supply line to the inlet port(at 6 o'clock position). In reaction plates, plug theremaining inlet port. See Table 4 for water port sizes.4.5.12 Slowly fill with water to purge all air fromwater cavities.Table 10Inlet and Outlet Water Port SizesSize Size24WCB2 SAE-1236WCB2 SAE-2048WCB2 SAE-204.5.13 Install pipe plug(s) in the outlet port(s) and applyappropriate water pressure 40 psig (2.7 bar) for the36WCSB and 48WCSB and 45 psig (3.1 bar) forthe 24WCSB measured at the inlet. Maintain thispressure for a minimum of 30 minutes.4.5.14 Check for leakage at O.D. and I.D. seal areas.NO leakage is allowed.4.5.15 If the assembly leaks, check the torque on eachscrew and re-test. If leaks still occur, the wearplate(s) or sealant groove may be damaged.Repeat procedure from section in front of 4.5.1.4.5.16 Follow steps in Section 4.9 to reassemblethe WCSB tensioner / brake assembly.4.5.17 Machining of the wear surfaces is required forthe 36WCSB and 48WCSB tensioner / brakeassemblies after replacement of the wear platesor the adjoining friction material. See Figure 16 formachining specifications.

See Section 4.3.4.6.1 Disconnect the air supply lines and remove thescrews (20), washers (17) and spacer tubes (27)attaching the cylinder (19) to the pressure plate (13).4.6.2 Carefully slide the cylinder off of the spring housing (16)or piston (33) out of the mounting flange/cylinder (112).CautionDo not use compressed air to remove the cylinderfrom the spring housing.4.6.3 Remove the cylinder seals from the spring housing(16) or piston (33) and thoroughly clean the sealgrooves in the spring housing or spring housing.4.6.4 Insert new seals into the grooves, noting theorientation of the seals per Figure 17.Figure 17
