Shaft Seal Assembly Servicing
When servicing the shaft seal, extreme care must be
taken when removing or installing the parts to prevent
damage to the lapped surfaces and other seal parts. The
portion of the shaft upon which the seal fits must be
free of scratches, burrs and dirt, and the seal housing
cavity must be clean.
Removal Of Seal Assembly (See Figure 10 on
page 37 and Figure 11 on page 40)
1. Remove the sheave and key from the shaft.
2. Remove the seal retainer plate bolts and gently re-
move the seal plate.
3. Remove the seal assembly from the shaft.
4. Clean all parts to be reused.
Installation Of Seal Assembly
1. Check all surfaces to make certain nicks and burrs
do not exist.
2. Wash all parts of the seal assembly in clean YORK
Refrig eration Oil.
3. Oil shaft with refrigeration oil to allow new seal to
be pushed into position.
4. Put on spring holder and spring. Be sure that
spring is centered in spring holder.
5. Slide the assembly along shaft just far enough to
center in spring and hold spring in place. Do not
compress the spring at this stage.
6. Before putting on end plate, thoroughly clean and
oil with 300 viscosity refrigeration oil on both seal-
ingfaces.Installoatingseatsinendplateasfol-
