Auger housing disassembly: Impeller removal
1. Remove the auger shaft assembly, complete with the auger
transmission, impeller shaft, and impeller. See Figure 4.29.
Description:
• The impeller is fastened to the impeller shaft by two roll
pins: one in front of the impeller, and one behind it.
• The front roll pin can be reached easily once the impeller
shaft is out of the snow thrower.
• The rear roll pin is recessed into the back of the impeller.
2. Drive out the spiral pin located in front of the impeller using
a 1/4” pin punch. See Figure 4.30.
NOTE: Use the correct size and type of punch.
• If an under or over size punch is used damage to the spiral
roll pin or shaft can occur.
• A pointed punch will spread the roll pin, binding it in the
hole.
3. Slide the impeller forward to reach the rear roll pin.
4. Drive out the spiral pin located behind the impeller using a
1/4” pin punch. See Figure 4.31.
5. Install the impeller by reversing the steps used to remove it.
