3. Remove the two carriage bolts on the chute control
rod (Fig. 086).

4. Support the auger and traction with blocks of wood.
5. Remove three capscrews down each side
connecting the auger to the traction assembly and
separate the sections (Fig. 087).

1. Apply a light coat of anti-seize to the auger shafts
and the impeller shaft. Install the impeller and
augers and secure with the capscrews and locknuts.
On models with the pivoting scraper, install the
scraper over the ends of the auger shaft. Slide the
auger shaft bearings on the ends of the auger shaft.
2. Insert the impeller shaft through the bearing in the
rear of the auger housing. The bearing mounting
bolts should be slightly loose at this time. (Note: if
the auger and traction assemblies are connected,
apply a light coat of anti-seize to the impeller shaft
and install the auger pulley at this time. If not, the
pulley can be installed in step 5.)
3. Secure the auger shaft bearings to the auger side
plates with 2 capscrews on each side. On models
with the pivoting scraper, install the scraper springs.
4. To ensure the impeller shaft bearing has aligned
itself with the shaft, strike it a couple of times with a
rubber mallet. If the auger and traction assemblies
are not separated, use a block of wood. Place it on
the auger shaft and strike the wood with a hammer.
The jolt to the shaft aligns the bearing. Secure the
bearing.
5. Apply a light coat of anti-seize to the impeller shaft
and install the impeller pulley. Push the auger shaft
to the rear and push the pulley forward and secure.
There should be no more than 1/8” (3mm) front to
back movement in the shaft.
6. Once separated, the auger pulley is in the open.
Once the pulley and key have been removed,
perform the preceding steps 12-14 to complete
auger removal.
