INSTALLATION (All VSS Models)

A)Install the gate rotor support by carefully tilting the roller bearing end of the gate rotor support towards the suction end of the compressor. The compressor input shaft may have to be rotated to facilitate the installation of the gate rotor sup- port.

Install gate rotor stabilizer. The gate rotor sta- bilizer (901) will hold the gate rotor support in place as the thrust bearing housing is being installed. If the gate rotor support is not re- stricted from moving, the gate rotor blade may be damaged.

B)Install the roller bearing housing (112) with a new O-ring (141). Tighten the bolts (152) to the recommended torque value.

C)When installing the thrust bearing housing (113), a new O-ring (142) must be used when the housing is installed. Lubricate the outside of the housing and bearings with clean compressor oil to aid in the installation. Due to the fit of the bearings on the gate rotor shaft, the thrust bear- ing removal and installation tool with the pusher shoe must be used. Turn the jacking screw clock- wise. This will push the thrust bearings onto the shaft and push the housing assembly into the frame. Install the inner retainer (115) and bolts (151) using Loctite® 242 thread locker. Tighten the bolts to the recommended torque value.
