23. Check the clearance between the entire gate rotor blade and the shelf, rotate the gate rotor to ﬁnd the tightest spot. It should be between 0.003-0.004“ (0.076-0.102 mm). Make adjustments, if neces- sary. It is preferable to shim the gate rotor blade looser rather than tighter against the shelf, see Figure 5-20.

24. After clearance has been set install a new O-ring (143) on bearing housing cover, install cover and tighten the bolts to the recommended torque value.

25. Install side cover with a new gasket. Tighten the bolts to the recommended torque value. The unit can then be evacuated and leak checked.

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

gate rotor blade and partition.
