SECTION 8: Repair and Replace (continued)
8.4.1.1.3.2. The distance from the finished face of the housing to 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 8).
8.4.1.1.3.3. 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.
8.4.1.1.3.4. Press cones of the tapered bearings onto the worm shaft
and insert the worm shaft in the housing.
8.4.1.1.3.5. Assemble bearing cups, shims and caps and establish pre-

cups until the dimension between the worm bearing
shoulder and the finished housing bore, as recorded at the
time of disassembly, is duplicated (see Figure 8).
NOTE: Do not discard any of the shims. Make
adjustments in pre-load by shifting shims from one
bearing cup to the other.
8.4.1.1.3.6. Replace cover plate and refill with oil. Refer to Chart 1 & 3
for quantity and specification.
8.3.2. Winsmith Worm Gear Reducer
NOTE: Due to its modular and hollow shaft design, it is not considered
economical to replace components only in these reducers. Except for seal
or other oil leak problems, replacement of entire reducer is recommended.
8.3.3. Brison Gear Motor
NOTE: May come with 1/11 HP or 1/4 HP motor depending on reducer ratio.
It is not considered economical to repair or replace components only. Replacement
of the entire product is recommended.
