E)Remove plug on the thrust bearing housing. Loosen the socket head cap screw that is located underneath the plug. This secures the inner races of the thrust bearings to the spindle.

F)Remove bolts that hold the thrust bearing hous- ing to the compressor. Insert two of the bolts into the threaded jacking holes to assist in removing the bearing housing from the compressor. When the housing is removed, there will be shims be- tween the spindle and thrust bearings. These control the clearance between the shelf and gate rotor blades. These must be kept with their respective parts for that side of the compressor.

G)Remove the bolts from the roller bearing housing. After the bolts have been removed, the housing can be removed from the compressor.

H)To remove the gate rotor support, carefully move the support opposite the direction of rotation and tilt the roller bearing end towards the suc- tion end of the compressor. The compressor input shaft may have to be turned to facilitate the removal of the gate rotor support. On dual gate versions, repeat the procedure for the remaining gate rotor support assembly.
