Section 7- Disassembly - Kohler KT17 Service Manual

SECTION 7 - DISASSEMBLY
WARNING:
A
Before working on engine, remove the
spark plugs to prevent unintentional
starting or compression kickback
when rotating engine by hand. To
prevent dirt and residue from falling
into combustion chamber, clean area
around plugs before removing.
The following sequence is suggested for complete
disassembly of an engine. The procedure may
have to be varied slightly to accommodate special
equipment.
All parts should be thoroughly cleaned - dirty
parts cannot be accurately gauged or inspected
properly for wear or damage. There are many
pommercially available cleaners that quickly re-
move grease, oil and grime accumulation from
engine parts. If such a cleaner is used, follow the
manufacturers instructions carefully, and make
sure that all trace of the cleaner is removed before
the engine is reassembled and placed in operation.
Even small amounts of these cleaners quickly
break down the lubricating properties of engine
oils.
EXTERNAL COMPONENTS
Follow the steps below when removing external
components. Refer to the appropriate sections in
this manual when servicing these parts.
1. Remove air cleaner assembly.
2. Disconnect low tension wiring from coil and
breaker point assembly, and high tension leads
from spark plugs. Disconnect other wiring
harnesses as necessary.
3. Remove the governor arm from governor clamp
then disconnect the governor linkage.
4. Disconnect the fuel line from carburetor.
5. Disconnect the breather hose from the intake
elbow (early KT17 models only).
6. Remove the intake manifold with carburetor
and intake elbow intact.
If necessary, the carburetor and intake elbow
can be removed from the intake manifold at
this time.
NOTE: Some Series II engines may be equip-
ped with a throttle and choke control mounted
41
on the intake manifold. Disconnect these con-
trols before removing carburetor. See Section
4, Figure 4-8.
7. Remove exhaust manifolds.
8. If so equipped, remove the grass deflector
attached to the blower housing.
9. If so equipped, remove the grass screen from
flywheel.
10. Remove the blower housing and other baffles
and shrouds.
If necessary, remove the rectifier-regulator
from blower housing.
Flywheel

hold the flywheel when removing the flywheel
retaining screw and washer.
Figure 7-1. Using Strap Wrench
WARNING:
A
Improper procedures for removal of
the flywheel can lead to a cracked
flywheel and broken crankshaft. This
not only results in extensive engine
damage, but presents a serious threat
to the safety of persons close by, since
broken fragments may possibly be
thrown from the engine.
When removing the flywheel:
DO NOT use a flywheel puller that
