Ignition System Tester
Spark Tester 25 455 01-S can be used to test the
ignition system on all Kohler engines, except those
that have CD ignition.
Water Manometer, Vacuum/Pressure Tester
The water manometer, 25 761 02-S, and
vacuum/pressure tester, 25 761 22-S, are used for
testing crankcase vacuum. They can also be used for
testing exhaust back pressure and for adjusting some
gaseous fuel regulators.
Cylinder Leakdown Tester
25 761 05-S Cylinder Leakdown Tester is a valuable
alternate to a compression test on these engines. 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 on
page 3.4 of this manual.
Rocker Arm/Crankshaft Tool
If you don't have a spanner wrench to lift the rocker
arms or to turn the crankshaft, you can make a tool 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. If it is a
Posi-Lock rod, you will also need to remove the studs.
If it is a Command rod, you will need to grind off the
aligning steps, so the joint surface is flat. Find a 1"
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". Kohler Part No. 12 468 05-S
can be used if you don't have the right size on hand.
Assemble the capscrew and washer to the joint
surface of the rod, as shown in Figure 2-1.
