Special Tools You Can Make
Flywheel Holding Tool
A flywheel holding tool can be made out of an old
junk flywheel ring gear as shown in Figure 2-1, and
used in place of a strap wrench.
1. Using an abrasive cut-off wheel, cut out a six
tooth segment of the ring gear as shown.
2. Grind off any burrs or sharp edges.
3. Invert the segment and place it between the
ignition bosses on the crankcase so the tool teeth
engage the flywheel ring gear teeth. The bosses
will lock the tool and flywheel in position for
loosening, tightening, or removing with a puller.

Rocker Arm/Crankshaft Tool
A spanner wrench to lift the rocker arms or turn the
crankshaft may be made out of an old junk connecting
rod.
1. Find a used connecting rod from a 10 HP or
larger engine. Remove and discard the rod cap.
2. Remove the studs of a Posi-Lock rod or grind off
the aligning steps of a Command rod, so the joint
surface is flat.
3. Find a 1 in. long capscrew with the correct
thread size to match the threads in the
connecting rod.
4. Use a flat washer with the correct I.D. to slip on
the capscrew and approximately 1” O.D. (Kohler
Part No. 12 468 05-S)
.
Assemble the capscrew
and washer to the joint surface of the rod, as
shown in Figure 2-2.
