Place spring retainer and spring onto motor shaft. Lightly
oil shaft
(DO NOT use grease) and inner surface of
bellows of rotating member. With fi nished end away from
motor, slide rotating member over bullet and onto shaft
until it engages spring (see Fig. 9). Carefully assemble
shaft to seal plate as per section F-3.3. It is extremely
important to keep seal faces clean during assembly. Dirt
particles lodged between these faces will cause the seal
to leak. When seal plate is assembled to motor, it will
properly align and seat the seal (3) and bearing (4). Follow
complete reassembly instructions as per section F-3.3.
F-4.3) Replacing Exclusion Seal:
The exclusion seal (14), helps to keep debris away from the
shaft seal where it could cause damage. The exclusion seal
should be replaced whenever the shaft seal is replaced. To
replace the exclusion seal, pull the old seal off the shaft, and
slide the new seal on with the thin lip toward the motor. Be
sure not to damage the lip of the seal. Finger pressure is all
that is needed to install the exclusion seal.
