To further assist in disassembly, a flywheel
removal tool (part no. 1116 893 0800) is
included in the tool kit.
After the the piston stop has been installed
and the crankshaft blocked from movement,
remove the flywheel nut. Thread the puller
onto the crankshaft stub until contact with the
flywheel is made, now unscrew the puller ½
to 1 full turn.
While holding the flywheel, use a suitable tool
to tap the end of the puller to release the
flywheel.
Specialty abrasive pads are included in the
tool kit that greatly ease and reduce repair
times for cleaning gasket surfaces,
combustion chambers, valve seats, and
exhaust ports on any small engine.

The abrasive pads work ideally with a small
air powered right angle grinder. A standard
drill motor can also be used although a drill
is slower and requires a little more time to
clean the components.
The 2" abrasive disk is ideal for quickly and
easily cleaning away gasket sealant and
cleaning gasket surfaces. It is important to
use only light pressure when using this tool.
If excessive down pressure is used, the
abrasive disk will quickly wear and require
replacement.
The abrasive cleaning pads and disks have
several uses. Page 6 and 7 list some of the
applications and part numbers of the various
size pads and disks that are included in the
tool kit.
