Auger Gearbox Service
AUGER GEARBOX DISASSEMBLY /
SERVICE
Once the auger gearbox assembly is removed from the
housing the repair process is the same for all models.
The only variables are what type of lubricant is used
(see the chart on Introduction page 1), whether the
impeller is removable from the shaft (on some models
the impeller is welded to the shaft) and how the
gearbox case halves are sealed.

4.
Remove the 8 or 9 self-tapping screws that hold
the gearbox halves together. Note: On a model
that uses 90 weight gear oil, you may want to
place the gearbox over a pan when the screws are
removed. Then separate the gearbox halves
(Figure 24).
Auger gearbox disassembly:
1.
With the gearbox assembly removed from the
housing the first step is to slide the bearings off
the output shafts. (Model 38080 & 38065, also
slide the scraper off).
2.
All models use a cap screw, lock nut, and spacer
to connect the auger to the shaft (Figure 22).
Remove the cap screw, nut and spacer and slide
both augers from the shaft.

5.
The impeller shaft can now be removed
(Figure 25).

3.
Some models have the impeller welded to the
impeller shaft. Others use a combination of bolts,
set screws, and a key. If you see bolt(s) through
the impeller hub, remove them. Some may have
set screws, which only require being loosened.
The models with the setscrews also have a key
between the hub and shaft. Once the visible
retainers are removed, slide the impeller away
from the gearbox, the key will be uncovered.
Remove the key (Figure 23).
