necessary. It is preferable to shim the gate rotor blade looser rather than tighter against the shelf.

14. Once the clearance is set remove the spindle. Install new O-ring, apply Loctite 242 thread locker to the socket head cap screw clamping the thrust bear- ings to the spindle. Torque all bolts, see Appendix A.

15. Install side covers with new gaskets. Tighten bolts, see Appendix A. The unit can now be evacuated and leak checked.

Check for 0.003-0.004” (0.076- 0.102 mm) clearance between

gate rotor blade and partition.
