Eaton Airflex WSB11206 Installation, Operation And Maintenance Manual

EATON WSB11206 WCSB Tensioner / Brake with ORB Coolant Ports Installation, Operation and Maintenance Manual E-CLCL-II009-E August 2015 19WCSB tensioner / brake with ORB coolant portsXZ1XZ1Y-3Y-3Y-2Y-2Y-1Y-10 ptWWFigure 7Z-2Figure 7A(d) Measure gaps between the components atpositions W, X, Y-1, and if applicable, Y-2, and Y-3.See Figures 6, and 6a for the location of thosegap positions.For reference:The W-gap is the measurement between the endplate (117) and the stop plates (125) and is used todetermine when adjustment of the water-cooledsection of the WCSB tensioner / brake assemblyis required. This gap will increase as the WCSBtensioner / brake assembly wears.The X-gap is the measurement between the endplate (117) and the pressure plate sub-assembly (13)and is used to deter- mine when adjustment of theair-cooled section of the WCSB tensioner / brakeassembly is required. This gap will decrease as theWCSB tensioner / brake assembly wears.The Y gaps are measurements between the variouswear plate sub-assemblies and are used to helpevaluate the wear of the water- cooled friction discsand wear plates. These gaps will decrease as theWCSB tensioner / brake assembly wears.The wear limit for each of the Y gaps is the samefor Y-1, Y-2 or Y-3.Y-1 is the measurement between the mountingflange (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 isfound only on WCSB tensioner / brake assembly thathave three or more ‘water- cooled’ discs.Y-3 is the measurement between thereaction plate (30) and the end plate (117).e) Record the W, X, Y-1, Y-2, and Y-3 values measuredfor each of the gaps, and compare them against thevalues 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 WCSBtensioner / brake assembly should be removed fromservice and repaired with new wear components.g) If the value measured for all Y gaps (Y-1, Y-2 or Y-3) isgreater than the Y min value, proceed to evaluate themeasurement for gap W as follows:h) If the measurement for gap W is equal to or greaterthat the Wadjust value shown on Table 8, wearadjustment is required. Adjust the WCSB tensioner /brake assembly per the procedures listed in section4.2.2. If it is found that no wear spacers (29) existbetween the clamp tube (12) and stop plate (125)before adjustment is attempted, all wear adjustmentshave been previously performed in the water-cooledsection of the WCSB tensioner / brake assembly andbrake overhaul is required.i) If the gap measured for gap X is equal to or lessthan the Xadjust value, wear adjustment is required.Adjust the WCSB tensioner / brake assembly per theprocedures listed in section 4.2.2. If it is found thatno wear spacers (29) exist between the clamp tube(124) and stop plate (125), all wear adjustments havebeen previously performed in the air-cooled sectionof the brake and replacement of the friction discs(118) and disc (119) may be required. Remove theWCSB tensioner / brake assembly from service andevaluate the condition of those components, usingTable 9 as a reference.
