loosening the setscrew (item 26) in the magnet hub (item
25) and slide off the motor shaft. Retain the key from the
motor shaft.

1. Place the motor spool (item 20) flat on the work surface.
2. Insert the containment canister (item 19) and driven
magnet (item 21) into the motor spool as shown. The
driven magnet is symmetrical and orientation does not
matter.
3. Inspect all O-Rings to be sure there is no damage such
as pinching prior to assembly.
4. Install O-Rings (items 6, 15) into each side of the center
housing (item 14) as shown. Some O-Ring lubricant may
help keep the O-Rings in place during assembly. Be sure
both O-Rings are fully seated into housing grooves.
5. Place the center housing, with O-Rings, onto the motor
spool, aligning the port connections between any set
of motor spool bolt holes as shown. Add the retaining
plates (item 32). Secure with eight bolts and washers
(items 16, 17). Tighten these bolts to the torque specified
on page 20. Always tighten fasteners in a progressive
“crisscross” pattern.

orientation does not matter. Install the housing liner
(item 11) and slide until it seats against the first bearing.
Install the idler gear (item 12) into the top hole in the
bearing until the gear seats against the first bearing.
