Insert drift through top ofbearing [15] in gearbox and drive seal [16] out bottom of
bore.
Reach up into bore from bottom opening with snap ring pliers and

GEARBOX ASSEMBLY
1 .
Clean all components (except bearings) with safety approved cleaning
solvent. Inspect components for defects and replace those found to be
defective.
NOTE: Ifplanetary pinion gear (Fig. 4 [11]) requires replacement, it is
likely that the planetary gear (Fig. 3 [20]) requires replacement also.
2.
If shafts have become slightly scored during the disassembly process, it is
necessary to polish the shafts with fine machinist's crocus cloth. An
especially smooth finish is necessary in the working seal area of the shafts.
Use care to avoid excessive removal of shaft surface or proper fit of
components will be lost.
3,
Always fit new rubber seals when rebuilding the gearbox. Use special
attention in examining the end of the shafts over which the seals will be
pushed. The slightest burring or scoring will abrade or cut the delicate seal
lips. A light polish of the shaft ends with crocus cloth is recommended.
Reassembly should be carried out in reverse ofthe disassembly procedure
stated above. Successful reassembly is very dependent on the cleanliness of
all surfaces, particularly the bores of housings, gears, and bearings,
as well
as the outer surface of shafts.
It is good to recheck each component for
cleanliness as it is picked up for reassembly.
Transmission should be progressively checked for smooth operation while
on the workbench by hand turning each assembly as it is installed.
Lubrication of the gear box should be done following its installation
on the
mixer. The helical and bevel housing compartments are filled to
a level 6"
(10 qt. SRM6O±) (16 qt. SRM8O+) from the top edge ofthe gear box with
SAE 140 gear oil.
