Next, insert the follower O-ring and the follower into
the seal sleeve.
Make sure the follower notch aligns with the notch
on the seal assembly. Before installing, clean and
lubricate the shaft and surfaces again.
29. Rotate the pump shaft until the locking pin location is
at 12 o’clock. Insert a screwdriver into the fan guard to
lock the shaft in place. Slide the seal assembly over
the shaft and align the seal locking pin notch with the
pin location on the shaft. Compress the seal assembly
spring with both thumbs to expose the locking pin hole
on the shaft. Install the locking pin into the hole on the
pump shaft. Make sure it is seated in the locking pin
notch on the seal assembly. There should be some
clearance behind the pin when you compress the seal
assembly. And, enough spring pressure to hold the pin
in the notch on the seal assembly.
30. Next, install the seal clamp ring with three screws
using the Phillips screwdriver. A magnetic screwdriver
is helpful if available. Install all three screws before
tightening. Then tighten the screws evenly. Do not over
tighten or break the screws.
31. Remove the screwdriver from the fan guard and rotate
the shaft until the shaft key-way is at the 12 o’clock
position. Reinsert the screwdriver into the fan guard to
secure the shaft. Align the woodruff or impeller key into
the center of the shaft key-way. Using an adjustable
wrench, apply pressure to the key by gently rocking
the wrench up and down on the shaft while tightening
the wrench. Continue until the key is firmly seated and
flat in the key-way. Be careful to not damage or score
the shaft.
