6.7.4 Installing Auger Drive Chain
To install the auger drive chain, follow these steps.
NOTE:
Blocking the left side of the drum may ease in
doing the next step.
1. Place the drive chain over the sprocket. Slide the left
hand housing toward the drum and mount just enough
to still leave the drive shaft 1/2 in. exposed. Bolt the
assembly together.
NOTE:
Remove block if used. Prior to hooking
up the chain to the drive assembly, rotate
drum in forward, and reverse a couple
of times. This will ensure the drum has
been rebuilt correctly.

NOTE:
The shoulder of the drive sprocket (A) faces the
auger.
