Remove the four carriage bolts, bell washers and
hex nuts which attach them to the snow thrower.
Reassemble new skid shoes with the four carriage
bolts, bell washers (cupped side goes against skid
shoes) and hex nuts. Make certain the skid shoes
are adjusted to be level.
To remove shave plate, remove the carriage bolts,
belleville washers and hex nuts which attach it to

Reassemble new shave plate, making sure heads
of the carriage bolts are to the inside of the housing.
Tighten securely.
