Gear Box Pre-Assembly
1. Start with one of the shafts (Item 17) and put one of
the gears (Item 10) over the shaft so the tooth side is
towards the turned end of the shaft. Align the keyway in
the gear with the keyway in the shaft and install one of
the keys (Item 8) in the keyway.
2. Install one set of shims (Item 11) onto the turned end
of the shaft. Press one of the bearing cones (Item 9)
over the turned end of the shaft. Be sure the bearing
cone is installed as shown in the illustration (Fig. 42B).
Install a retaining ring (Item 7) on the turned end of the
shaft.
3. Put one of the bearing cones (Item 12) over the other
end of the shaft and down against the hub side of the
gear. Be sure the bearing cone is installed as shown in
the illustration.
4. Repeat steps 1 - 3 with the other set of parts to
complete the assembly.
5. Put one of the caps (Item 16) down, with the machined
surface facing up. Install a new seal (Item 13) into the
cap with the open side toward the machined side of the
cap.
6. Install the bearing cup (Item 14) into the cap. Make
sure the bearing cup is installed as shown in the illus-
tration.
7. Repeat steps 5 - 6 with the other set of parts to
complete the two cap assemblies.
8. Take one of the shaft and gear assemblies and wrap
the end of the shaft with a piece of shim stock to keep
from cutting the oil seal on the keyway or splines. Put
the cap assembly down over the shaft so the bearing
cone (Item 12) on the shaft mates with the bearing cone
(Item 14) in the cap. Remove the shim stock from the
shaft that was used to protect the seal.
9. Press the bearing cups (Item 3) into both bearing
bores in the housing (Item 1). Make sure the cups are
installed as shown in the illustration. Install the plugs
(Item 2) into the tapped holes in the housing.
