Shear Bolt Replacement
The input driveline and side drive shaft are both pro-
tected by shear bolts in case of shock load from striking
an obstruction. To access the shear bolts, lift the
guards, (items 3 and 4). See parts section for bolt size
and grade.
■ Always use approved shear bolt as replacement
part. Using a hardened bolt or shear pin may re-
sult in damage to driveline or gearbox.
■ Before proceeding, read and follow all safety
rules.
1. Shut off tractor and remove the key.
2. Remove any obstructions from the auger, chain, or
sprockets.
3. To access the shearbolts, (items 1 and 2), lift the
guards, (items 3 and 4).
4. Remove the damaged bolt and rotate the auger by
hand to align the holes.
5. Install new shear bolt and nut shown in the parts
lists and tighten to the specification shown in the
Bolt Torque Chart.

WARNING
Auger Drive Chain Maintenance
The auger chain should be inspected every 25 hours.
New chain has a tendency to stretch, so it is necessary
to check the chain tension to prevent flopping around,
thus causing potential problems. Chain tension is pre-
set at the factory. If chain becomes excessively loose, it
may be necessary to readjust the idler sprocket, Figure
9.
NOTICE
■ Replacement chain should be only high quality
original equipment chain for longer life.
Drive Chain Adjustment
IMPORTANT: A tension too tight can cause premature
wear of the chain. It is important not to tighten the chain
to its maximum. Adjust the chain according to the fol-
lowing steps:
1. Loosen the bolt (item 1) securing the idler sprocket
to the snow blower.
2. Adjust the bolt height to obtain a deflection of 1/8'' in
one chain length.
3. Securely tighten the bolt (item 1) securing the idler
sprocket.
