TRANSMISSION
REASSEMBLY:
1. Clean all components except the bearings with safety approved cleaning solvent. Inspect all
components for defects and replace those found to be defective.
NOTE: All gears should be replaced as sets.
2. If any shafts have become slightly scored during the disassembly process, polish the shafts
with fine machinist's crocus cloth. Use care to avoid excessive removal of shaft surface or
proper fit of components will be lost.
3. Reassembly should be carried out in the reverse of the disassembly procedures as follows:
a. Reassemble and reinstall the vertical shaft assembly.
b. Reassemble and reinstall the power take-off assembly except the spur gear (Figure 5 [15])
c. Place the input assembly grease retainer (Figure 6 [14]) in place in the transmission
housing, then install the power take-off spur gear (Figure 5 [15]) on the power take-off
shaft and replace the retaining ring (Figure 5 [10]) on the power take-off shaft. Slide the
input assembly into the transmission housing and attach the grease retainer (Figure 6 [14])
to the input housing (Figure 6 [13]) with the 1/4-20 hex head cap screw (Figure 6 [8]) and
the flat washer and lock washer (Figure 6 [9 & 10]). Attach the input housing to the
transmission with the two 1/4-20 hex head cap screws (Figure 6 [11]), lock washers
(Figure 6 [9]) and strap washer (Figure 6 [12]).
4. Reassemble and reinstall the beater head assembly. Lightly lubricate the beater head screw
and torque the screw to 20 foot-pounds.
NOTE: The screw is left hand thread.
5. The transmission should be progressively checked for smooth operation while on the
workbench by turning each assembly as it is installed.
6. Lubrication of the transmission should be done following its installation on the mixer. Apply
Keystone Nevastane 5P7 grease to the spur gear and bevel gear meshes. This may be
simplified by feeding the grease into the rotating gear meshes. Caution should be exercised to
avoid entrapment of the applicator in the gear teeth. Insure the grease deflector (Figure 5[7])
is positioned to dynamically guide the lubrication into the bevel gear mesh.
