Original shave plate badly worn
With WD-40 or equivalent, spray the four nuts on the underside of the snow blower housing that hold the shave plate to the housing. Also spray the two bolts that hold the shave plate to the side of the housing. Let sit for a few minutes and using a 1/2" box end wrench remove the four nuts on the bottom of the housing. If necessary, apply heat with a torch to loosen. Using a 9/16" box end wrench, remove the nuts on the sides (these also hold the adjustable skid feet). It is recommended that the bottom bolts and nuts be replaced with 5/16-18 X 3/4" long zinc plated carriage bolts using zinc plated washers and ny-lock nuts. It is also recommended that all of th screw threads be coated with an anti- seize lubricant so disassembly at a later date will be easy.
