To remove/replace the Tracks:
NOTE: There is a spring loaded idler on both tracks, that
will take up the slack in the Tracks as they stretch.
Both of the spring loaded idlers need to be held
down when doing any work or adjustments to the
Tracks. Instructions on how to build a set of tools
to hold the idlers down are located at the end of
this chapter. See Figure 6.1.
1. Drain the fuel tank into an approved container.
2. Drain the oil out of the engine.
3. Carefully tip the snow thrower forward until it rests on
the auger housing opening.
4. Install the tools to hold the idler wheel down.
NOTE: To use the tools:
• Insert the forked end of the tool over the idler arm,
between the spring and the idler wheel.
• Rotate the idler away from the Track enough for
the flange on the opposite end of the tool to hook
over the front wheel. See Figure 6.2.
• Push the tool in to fully seat it.
• Repeat on other side of the machine.
NOTE: Both Tracks must be serviced at the same time.
Failure to do so can result in non-parallel Tracks.
