b. LIP SEAL (Figure 8) — Coat outside diameter of seal
with Permatex #3 or equivalent. Drive seal into seal
housing with the spring loaded seal lip away from the
driver. Wrap the keyway on tapered shank of drive shaft
with masking tape or light weight Kraft paper to protect
against damaging the seal lips. Coat the seal lips and
straight portion of the drive shaft with bearing grease.
Line up the keyway in the drive shaft with the hollow shaft
keyway and insert the drive shaft into the seal housing.
Remove the protective wrap and install the drive shaft
key. Insert the drive shaft into the hollow shaft. The seal
housing registers into the basic drive seal bore. Use the
thrust plate fastener Figure 7, to secure the drive shaft.
Refer to Table 3 for proper torque value. Install the seal
housing fasteners to secure the seal housing to the basic
drive. Refer to Table 4 for proper torque value. Reinstall
hollow shaft cover and proceed to Step 5.
c. PACKING GLAND SEAL (Figure 10) — First, wrap the
packing around the drive shaft adjacent to the tapered
portion of the drive shaft as shown in Figure 9. Cut the
packing to produce two complete split seal rings.
CAUTION: Do not mar the shaft’s seal surface.
