Maintenance Instructions REPLACING/REPAIRING
Drive Chain
The drive chain should be replaced if, when adjust-
ed properly, it can be pulled away from the front of
the auger sprocket more than 1/2 of the height of
a tooth on the sprocket. Running the snowblower
with a worn chain increases wear on the sprock-
ets.
1. Remove the chain guard cover and the LH au-
ger guard. Refer to LUBRICATION of Drive
Chain in this section for removing chain guard
cover.
2. Loosen the chain tension block mounting nut
and bolt. Position the chain tension block so the
chain has as much slack as possible. Tighten
the chain tension block mounting nut and bolt
slightly to hold the chain tension block in this
position.
Loosen Chain Tension
3. Turn the auger until the master link for the chain
is accessible.
4. Remove the master link from the chain and re-
move the chain from the sprockets.

5. Place the new chain on the sprockets and in-
stall the master link. Be sure to install the clip
on the master link properly. The closed end of
the clip should point in the direction of chain
travel.
Proper Master Link Clip Installation
6. Adjust the chain. Refer to ADJUSTMENTS of
Drive Chain in this section.
7. Reinstall the auger guard and the chain guard
by reversing the removal procedures.
