GEARING REASSEMBLY
Planetary Gearing
Place a small amount of grease in each planet gear, as illustrated
at right, and place on a smooth clean surface. Insert a planet pin
— notched end up — in each gear. Then, install the correct
number of rollers ( 12 ) around each gear. Grease will hold the
rollers in position when the planet gears are removed.

Timing of the Step Reduction Gear Assembly
Assemble the planet gears into the planet cage, making sure the
notched planet pins fit over the planet cage washer. Rotate each
gear until the aligning hole — on the wnd of one gear — is
diametrically opposite the
“X”
mark of the other gear. Hold the
gears in this position and slip the planet cage into the internal
gear. This is important to avoid “wiping out” the gear teeth.
This is the only position where the gear teeth are lined up.
