Snowblower Reduction Chain Tension
Adjust the tension on the reduction chain as follows:
1. Remove PTO guard covering the reduction box.
2. Loosen the four (4) carriage bolts and nuts securing the reduction box assembly to the frame.
3. Using a pry bar, apply leverage to push the reduction box assembly down to increase tension on the
chain. The chain should have 1/16 to 1/8 in. of slack.
4. While applying downward pressure to maintain chain tension, tighten the four (4) carriage bolts and nuts
to 25 ft•lbs (34 N•m) as shown in Figure 4.8.
