SECTION 8
ASSEMBLY
FUEL PUMP
CAUTION:
A
Never install fuel pump on crankcase
before the case halves are assembled,
as fuel pump lever could be incorrectly
positioned below the cam. Correct
lever
position is above the cam. Fuel
pump damage and subsequent severe
engine damage could result iflever is
positioned below the camshaft. (See
Figure 8-30.)
NOTE: Replacement fuel pumps are available in
kit form from your Kohler parts supplier. They are
of a non-metallic design which effectively insu·
lates and prevents fuel from vaporizing inside the
pump, and are interchangeable with the metal
pumps. The kit includes the pump, new mounting
gasket and two flat washers.

Figure 8-30. Installing Fuel Pump
Installing Non-Metallic Pumps
1. Apply a small amount of a gasoline resistant
thread sealant to fuel fitting threads. Turn
fittings into pump 6 full turns and continue in
same direction until required position is
attained.
2. Install pump to engine using only the gasket
provided in the kit. If a thick insulating gasket
was used with the metal pump, discard it. It
could cause distortion of the flange while tight-
ening the mounting capscrews.
3.
Install the flat washers from the kit next to the
flange to prevent the lockwasher from damaging
the flange. (The lockwashers and mounting
screws from the old pump can be reused with the
new pump.)

4. Install the two 114-20 x 3/4" fillister head
screws, and lockwashers into fuel pump flange.
Position pump gasket on screws, then secure
pump to fuel pump mounting pad, which is just
to the right of the #2 cylinder barrel, toward the
flywheel end of the engine. Torque screws to
40-45 in. lbs. - do not overtighten.
5. Attach fuel hose to outlet side of fuel pump with
hose clamp.
STARTER MOTOR
1. Attach starter motor to the mounting flange on
the #2 side of crankcase just below the cylinder
barrel.
2. Secure starter with two grade #2, 1/4-20 hex
nuts and 1/4" lock washers.
FLYWHEEL
WARNING:
Improper procedures for installation
of the flywheel can lead to a cracked
flywheel and broken crankshaft.
This results in extensive engine
damage, and presents a serious
threat to personal safety, since brok-
en fragments may possibly be thrown
from a running engine.
When
installing the flywheel:
DO NOT apply grease or oil or any
lubricant to the taper of the crank-
shaft or hub of the flywheel, as this
will cause excessive stress to be dev·
eloped in the flywheel hub, and pos-
sible
cracking of the flywheel while
tightening.
DO NOT allow the key to be pushed
inward on the keyway while install-
ing the flywheel. If the key rides up
on the rounded surface at the end of
the keyway as shown in Figure 8-31,
it will act as a wedge and crack the
flywheel hub.
DO NOT reuse a flywheel if it has
been dropped or damaged in any
way.
DO NOT use a steel bar or any other
object between the flywheel fins to
hold the flywheel when the flywheel
nut is being torqued, as this could
break or crack flywheel fins, which
may fly off when the engine is
running.
