& Instructions
Ensure the shaft sealing surface and housing seal bore are
clean and free of all dirt and debris to avoid
introducing any contaminants into unit.
1. Grease the inside surface of seal that contacts shaft.
2. Select correct bullet and driver. Bullet and drive
shaft chamfer must align with each other leaving
no gap between the bullet and shaft. Bullet should
pilot on shaft diameter so bullet cannot shift side to
side, allowing step between bullet and shaft seal
diameter.
3. Press the new, greased shaft seal over a shaft bullet.
Closed face of the shaft seal faces the closed end of
the bullet.
4. With the shaft seal on the bullet, insert bullet over drive
shaft and into the seal pocket. Take care to ensure seal is
properly aligned with housing bore as seal is pressed in to
minimize chance of damaging seal.
5. Using the driver and a mallet, push the seal until the tool
bottoms on the pilot of flange.
6. Remove the tool and insert the retaining ring into the seal
pocket. A spacer is required, whenever there is a
significant groove in the shaft from the seal. (A maximum
of two spacers may be used before the shaft must be
replaced), place it between the shaft seal and the
retaining ring.
7. Using the tool and mallet, drive the seal, spacer(as
required if using, and retaining ring in until the retaining
ring snaps into place in the groove.
