Read the instructions carefully. The items refer to the parts list and service kits section.
Drawing 6, 2
Gear Train Assembly and Installation
Drawing 6: Combine the subassemblies for the Input Shaft Housings (Drawings 8-12), the Gear Box (Drawings 14-17), and
the Output Shaft Housing (Drawing 13).
Drawing 2: Lower the Gear Train Assembly (Drawing 6) into the Stem (pos. 15.1). The Transition Output Shaft (pos. 21)
should seat in the hole in the Tee Housing Base (pos. 30) with the corresponding flats lining up. The Gear Train Assembly
(Drawing 6) is properly installed when the Input Shaft Bearing Housing (pos. 8.1) is flush with the upper surface of the Stem.
Drawing 5, 1
Inlet Collar Assembly and Installation
Drawing 5: If the Stator (pos. 3) was taken out of the Inlet Collar (pos. 1) for inspection, insert it into the threaded side of
the Collar with the fins facing down.
Use duckbill pliers to pinch the Stator Retaining Ring (pos. 2) and replace it inside the Collar (pos. 1). The Retaining Ring should
seat evenly in the groove above the Stator and below the internal threads of the Collar.
Warning: Use caution when installing and removing the Stator Retaining Ring (pos. 2), as it is an exceedingly
stiff spring part. If improperly gripped, the Ring may slip out of the pliers and cause serious
personal injury.
Drawing 1: Lower the Inlet Collar Assembly (Drawing 5) down around the Rotor (pos. 7.1) so that it sits on the upper face
of the Input Shaft Bearing Housing (pos. 8.1). Align the holes of the Collar flange with the holes through the Bearing Housing
and the matching holes in the Stem (pos. 15.1).
Install the eight Inlet Collar Cap Screws (pos. 13) and corresponding Lock Washers (pos. 14) using a 3/16” Hex Key,
tightening the screws evenly in a star pattern to distribute shear stresses.
