6. Place the sleeve O-ring (3-914-9) onto the shaft, into the
sleeve counterbore. Verify that Dimension “A” (Figure 12) is
maintained, then using a pin spanner wrench and hammer,
securely tighten the shaft sleeve nuts (3-015-9). Then, drill
a shallow recess in the shaft through the set screw hole in
each of the shaft sleeve nuts. Lock each shaft sleeve nut
in position with cup point set screws (3-902-9). (See Figure
15) A low strength sealant, such as Loctite 271, can be
used to retain set screws.
7. Assemble casing rings (3-003-9). (See page 26 for
adjustable rings.)
8. Start heating bearings (3-026-2) so that they will be ready
when called for in step 11. Use dry heat from induction
heat lamps from electric furnace, or a 10-15% soluble oil
and water solution.
9. Assemble oil seals (3-177-9) in each bearing cover. Install
gaskets (3-409-9) on each bearing cover.
56;,! Seal lip or pressure side of oil seal must point
towards the end of the shaft that the oil seal is assembled
on. (See Figures 25 and 26)
10. Slide deflectors (3-136-9) and bearing covers (3-018-3, -4)
on the shaft. Install snap rings (3-915-9). Install thrust
washer (3-078-9) on the outboard end.
For ease of assembly and protection of rubber parts while
sliding rubber parts onto shaft, cover O-ring groove, key-
ways, and thread with electric tape.
56;,! Inboard bearing cover (3-018-3) is approximately
1/4 inch less in width than the outboard bearing cover
(3-517-4). This is the only dimensional difference.
11. Press heated bearing (3-026-2) on shaft against snap ring
or thrust washer. Install locknut (3-516-4) and lockwasher
(3-517-4) on outboard end. Make certain locknut is
secured and then bend over tab on lockwasher.

Refer to page 26 for installation of oil lubricated parts.
13. Assemble oil seals (3-177-9) in each bearing housing.
Refer to 56;, under number 9 above for direction of oil
seal.
14. Slide bearing housings (3-025-2) onto shaft (3-007-0) over
bearings (3-0262).
