Two-Stage Snowblower Reduction Chain

The reduction chain should be replaced if, when adjust-
ed properly, it can be pulled away from the front of the
reduction sprocket more than 1/2 the height of a
tooth on the sprocket. Running the snowblower with
a worn chain increases wear on the sprockets.
1. Remove the 1/4 x 7-1/2 in. bolt, lock washer, and
nut from the reduction box cover.
2. Remove the box cover from the reduction box.

4. Remove the master link from the chain and remove
the chain from the sprocket.
5. Place the new chain on the sprockets and install
the master link. Install the clip on the master link
properly. The closed end of the clip should point
in the direction of chain travel.
