III. PUMP END ASSEMBLY TO MOTOR
Motor Preparation
a. The entire C•Shell pump is built onto the motor, so to begin assembly motor must be firmly secured to a work surface. The feet can be clamped
®
or bolted onto the surface to prevent movement or tipping. The motor's mounting face should hang over the edge of the work surface so there is
no interference during assembly (See Figure 1). A smaller motor is more prone to tipping when the wet end is installed than a larger motor, but
all should be firmly secured.
b. Prepare motor by removing all stickers and wiping off excess lubricant from the shaft. Remove the Square Key (9) and fit the Shaft Sleeve (8)
over the motor shaft. Place the Square Key (9) into the motor shaft keyway along with the Shaft Sleeve (8) and cut the Square Key (9) stock so
that it does not protrude past the shoulder of the Shaft Sleeve (8). (See Figure 7 & 8).
c. Remove Square Key (9) and Shaft Sleeve (8) from shaft. Ensure there is a light application of anti-seize on the motor shaft.
d. Apply a light application of Anti-Seize (Item H) to front motor face/flange.
e. Apply a light application of Anti-Seize (Item H) to shaft.
LIGHTLY LUBRICATE ALL SEAL O-RINGS TO PREVENT DAMAGE & HOLD O-RINGS IN PLACE DURING ASSEMBLY.
