Special Tools You Can Make
Flywheel Holding Tool
A fl ywheel holding tool can be made out of an old
fl ywheel 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 that the tool
bosses will lock the tool and fl ywheel in posi-
tion for loosening, tightening or removing with a
puller.
Figure 2-1. Flywheel Holding Tool.
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 fl at.
3. Find a 1 in. long capscrew with the correct thread
size to match the threads in the connecting rod.
4. Use a fl at washer with the correct I.D. to slip
on the capscrew and approximately 1 in. O.D.
(Kohler Part No. 12 468 05-S). Assemble the cap-
screw and washer to the joint surface of the rod,
as shown in Figure 2-2.
