17. Replace the belt cover using the 3/4” wrench.
Belt Alignment
If the unit has premature belt wear, breakage or pulley
problems, the issue may be incorrect alignment or
excessive belt tensioning. All pulleys must be aligned
directly above each other to ensure belt integrity.
1. Use a long straight edge (carpenters square) to
check alignment during belt tensioning or belt
replacement time.
2. By laying the straight edge against the outer face of
the lower pulley, the square will extend up and rest
against the outer face of the upper (engine) pulley. If
the straight edge does not rest against the entire
face of the engine pulley, move the engine pulley in
or out to obtain alignment.
3. If replacing pulleys (top or bottom) be sure to place
the pulley on the same plane as the original one to
ensure alignment.

1. Use a screwdriver to flatten out the tabs that secure
the lock nut to the lower pulley.
2. Remove the lock nut on the shaft by putting the
screw driver on one of the tabs and hitting it with a
hammer or mallet. Remove pulley from shaft.
NOTE : The lock nut has left hand threads, therefore it
must be rotated clockwise to loosen it.
To avoid injury from unexpected start up, disconnect
spark plug wire before you service your unit.
