Special Tools You Can Make
Flywheel Holding Tool
Flywheel removal and reinstallation becomes a "snap"
using a handy holding tool which can be made out of
an old "junk" flywheel ring gear as shown in Figure 2-2.
Using an abrasive cut-off wheel, cut out a six tooth
segment of the ring gear as shown. Grind off any burrs
or sharp edges. The segment can be used in place of
a strap wrench. Invert the segment and place it
between the ignition bosses on the crankcase so that
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.

2.2
Rocker Arm/Crankshaft Tool
If a spanner wrench to lift the rocker arms or turn the
crankshaft is not available, a tool may be made for
doing this out of an old junk connecting rod.
Find a used connecting rod from a 10 HP or larger
engine. Remove and discard the rod cap. Remove the
studs of a Posi-Lock rod, or grind off the aligning steps
of a Command rod, so the joint surface is flat. Find a 1
in. long capscrew with the correct thread size to match
the threads in the connecting rod. Obtain a flat washer
with the correct I.D. to slip on the capscrew and an
O.D. of approximately 1 in. or use Kohler Part No.
12 468 05. Assemble the capscrew and washer to the
joint surface of the rod, as shown in Figure 2-3.

Cylinder Leakdown Tester
A Cylinder Leakdown Tester (SPX Part No. KO3219,
formerly Kohler 25 761 05-S) is a valuable alternate to
a compression test on these engines. See Figure 2-4.
By pressurizing the combustion chamber from an
external air source, this tool can determine if valves or
rings are leaking. Instructions for using this tester are
found in Section 3 of this manual.
