12. See Figure 3-91. Install spacer in seal ID. With the open
(lipped) side facing outward, center seal/spacer assem-
bly over bearing bore.
13. See Figure 3-92. Center seal/spacer driver over seal, so
that the sleeve (smaller OD) seats between seal wall and
garter spring. Fit the sleeve of the driver handle into the
recess at the top of the seal/spacer driver. Using a rub-
ber or plastic mallet, drive the seal and spacer simulta-
neously into the bore until the spacer makes solid
contact with the Timken bearing cage. Remove the driver
handle and seal/spacer driver.
1CAUTION
Do not remove the spacer after installation or the new
seal will have to be discarded and the procedure
repeated.
14. Apply a thin coat of DOW CORNING SILASTIC or 3-M
800 sealant to crankcase joint faces.
