Snowblower Reduction Chain
The reduction chain should be replaced if, when adjusted for proper tension, it can be pulled away from
the top 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 bolts securing the PTO guard to the frame and remove the guard as shown in Figure 4.4.
2. Turn the reduction box drive shaft until the master link for the chain is accessible.
3. Remove the master link from the chain and remove the chain from the sprocket.

properly. The
closed end of the clip
