the unmarked face of the gear, noted at the time of
disassembly, must be duplicated, either by grinding the
adjusting spacer or adding shims (see Figure 15).
8.5.1.1.3.3. Tighten the clamp screw in the split hub of the gear and
assemble the gear retaining screw and washer, if such
were provided as part of the factory installation.
8.5.1.1.3.4. Press cones of the tapered bearings onto the worm shaft
and insert the worm shaft in the housing.
8.5.1.1.3.5. Assemble bearing cups, shims and caps and establish pre-

NOTE: Do not discard any of the shims. Make
adjustments in pre-load by shifting shims from one
bearing cup to the other.
