Assembly and Parts, Cont.
Drive End Cap Assembly Cont.
90217
Drive Motor
The Motor is held in place by two 1/2" screws. The screws should be “snug.” The brass pinion gear on
the Motor should engage the plastic Drive Gear. The wires should be securely fastened to the Control.
93238 Drive Gear
The Drive Gear is assembled to the Slide Cam by means of a “keyed” opening which transfers the
“torque” generated by the Motor to the rest of the drive system. If the drive system becomes jammed,
this opening can become “rounded” causing the gear to turn, but not the Piston Slide Cam. If this
occurs, clear the jam and replace the Drive Gear and Piston Slide Cam (93217).
93219 Piston
Slide Cam Cover
The cover secures the Piston Slide Cam (93217) in place and acts as a bushing for the Cam Shaft.
93217
Piston Slide Cam
This is the “heart” of the drive system. There is a threaded stainless steel shaft that runs through the
main drive axle. The Drive Gear is attached at the short end and the Magnet Disc at the other end.
The Slide Cam is assembled inside of the Piston Slide (54202). This Cam Shaft should turn freely
before the Motor is assembled.
93583
Drive End Cap
Seals the two openings on the Main Valve Body. The larger diameter opening is sealed with an O-
Ring used as an axial or “face” seal. The O-Ring sits in a groove in the End Cap. This groove must be
free of defects such as pits or scratches and also free of debris. The smaller diameter seal is
accomplished with an O-Ring used as a radial seal. The O-Ring should be placed on the male boss
on the End Cap. When assembling the End Cap to the Valve Body, care should be taken to make
sure the small O-Ring is aligned with the opening in the Valve Body and that the large O-Ring stays in
the groove in the End Cap. If misaligned, the O-Rings can become pinched and leak.
54202
Piston Slide
The Slide should move freely inside the End Cap Housing.
93601-JG Brine
Valve Housing
Assembly
Attaches to the Drive End Cap with two 3/4" thread cutting screws and has one O-Ring seal. The
O-Ring is used as a axial or face seal. The O-Ring sits in a groove in the Brine Valve Housing. The
groove and the face seal must be free of defects such as pits and scratches or debris.
53522 Drive
Piston Assembly
The Drive Piston attaches to the Piston Slide (54202) by placing the “slot” of the Piston onto the
matching flat of the Slide. To remove Piston, rotate Piston 90° counterclockwise. To replace Piston,
rotate 90° clockwise until you hear an audible “click.” See reference drawings below.
