Assembly and Parts, Cont.
Drive End Cap Assembly Cont.
90217 Drive Motor
The Motor is held in place by two, 1/2-inch self-tapping screws. The screws should be “snug.” The
brass pinion gear on the Motor should engage the plastic Drive Gear (93238). The wires should
be securely fastened to the Controller.
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 (93238) 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 (93238) is attached at the short end and the Magnet Disk
(54502) 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.
53322 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.
