Canrig LWCV Assembly Instructions LWCV CHECK VALVE INSTALLATION INSTRUCTIONS Procedure for installing check valve in LWCV hydraulic valve stack 1) Relieve pressure on system by turning HPU off. Lock out HPU as necessary to prevent start-up during the check valve installation. 2) Relieve pressure on system by operating link tilt or other hydraulic function. 3) Thoroughly clean valve stack and manifold around valve stack to eliminate contamination of hydraulic system. 4) Remove solenoid from top of valve stack. 5) Remove four nuts from retaining studs on valve stack. 6) Remove all valves (proportional valve and pressure reducing valve(s) from valve manifold. Note location of each valve as it is critical that they are reinstalled in their original orientation. 7) Unscrew four studs from hydraulic manifold and discard. 8) Screw new longer studs (supplied with kit) into manifold block. Note that the studs supplied with the Rexroth valve kit are not interchangeable with the shorter Sun valve kit studs. 9) Identify check valve supplied with kit- refer to Figures 1a and 1b. (Due to availability of check valves, Canrig may supply either style valve as shown with kit -valves are fully interchangeable.) Pay particular attention to the orientation of the valves during installation. Figure 26a Sun Check Valve Figure 1b Rexroth Valve 10) Canrig manifolds assemblies vary in design depending upon the Top Drive model. Refer to Figures 2a and 2b to determine proper orientation of valve and manifold style. Sun style valve is shown in illustration - Rexroth installation is similar EXCEPT that orientation is accomplished with alignment holes rather than notch alignment (see Figure 3). Note that manifold components as shown in Figure 2 may vary slightly from illustration. Revision January 2009 Page 17 of 22
