2. Check the backlash of gears (2) and (3), as follows:
3. Measure the maximum, angular, displacement (A),
of sheave (B), by measuring the distance (C). The
distance (C), should be 0.1 - 0.6 mm.
4. If distance (C), is not within 0.1 - 0.6 mm, add or re-
move shims (4) to obtain the correct backlash. Re-
peat step 3.
5. With the backlash correctly adjusted, and with the
gearbox bolted together, use a grease gun to fill
the gearbox through the grease nipple, with NLGI 2
grease until the grease exits the breather.
