Gearbox Assembly
1.
Clean and lubricate the front & rear bearing areas of the drive &
idle shafts with oil.
Fit the front bearing, spacer and rear bearing on the shaft
sequentially by press (or heat up to 120
℃
(250F)).
Position the gearbox (1) with wet end side facing up and be sure
to support the gasket face (downside) carefully in order not to
damage it.
Clean and lubricate the front and rear bearing areas with oil.
Insert the shaft perpendicularly one by one to the gearbox
properly. There should be a tight sliding fit between the gearbox
and the bearing outer rings. Press the shaft into the gear case
until bearings are fully seated.
2.
Lubricate and install the front bearing oil seals set into the
bearing glands.
Place the front bearing gland set on both shafts. Take care for
the Oil seal spring inside of the gland set: it should not be
deflected during insertion. Set the Bolt & washer, and tighten.
3.
Place the gear spacer (16) over the shafts.
Clean and lubricate the gear area of the shaft and the face of the
lock washer with oil.
Align both shafts so that the gear keyways (10) are on to the 12
o’clock position shown in Figure 41.
