SERVICE INSTRUCTIONS
Drive Chain
The drive chain should be replaced if, when adjusted
properly, it can be pulled away from the front of the au-
ger 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 sprockets.
1. Remove the chain guard cover and the LH auger
guard. Refer to LUBRICATION of Drive Chain in
the Lubrication 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 remove
the chain from the sprockets.
Remove Master Link
5. Place the new chain on the sprockets and install
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 Tension in this section.
7. Reinstall the auger guard and the chain guard by
reversing the removal procedures.
