Gearbox Reassembly
Refer to Figure 20.
NOTE: Repair to this gearbox is limited to replacing bearings, seals, and gas-
kets. Replacing gears, shafts, and a housing is not cost effective. Purchasing a
complete gearbox is more economical.
1.
Clean housing, paying specific attention to areas where gaskets will be
installed.
2.
Wash housing and all components thoroughly. Select a clean area for
gearbox assembly. Replace all seals, bearings, and gaskets. All parts
must be clean and lightly oiled before reassembling.
3.
Insert output bearings (6 & 26) in the housing, using a round tube of the
correct diameter and a hand press.
4.
Slide output shaft (4) through both bearings (6 & 26) until it rests against
bearing (6).
5.
Slide shim (16) over output shaft (4).
