. Now, disassemble the components on the crank-
shaft. If you have an impact wrench, the large nut on
the crankshaft can be spun off. If you must remove it
manually, wedge a bar or large screwdriver into the
BBC flywheel (Fig. 223). This will hold the crankshaft
so the nut can be removed.
8. Roll the self-propel belt off the pulley and remove the
pulley and the key in the crankshaft.
9. Inspect the pulley. One end of the keyway is
blocked off. If that is broken, the pulley will bounce
up and down during use and make a rattling noise
(Fig. 225). There are two bumps on the outside
of the pulley that are intended to engage two
holes in the flywheel. If this wall is broken out or
the bumps on the pulley are damaged, the pulley
must be replaced. Usually this is caused by an
error in assembly. Refer to “Idler Arm System
Assembly (Recycler/Rear Bagger)” on page 6-25 for
instructions to avoid this.

Remove the hub assembly and brake drum. The
flywheel is pressed onto a taper on the crankshaft.
It might require a tap with a hammer to loosen (Fig.
224).
