Kohler KT17 Service Manual

SECTION 7
DISASSEMBLY
WARNING:
(Cont.)
CAUTION:
A
grips the outside diameter of the fly-
wheel, as damage to the flywheel could
result.
DO NOT use any type of bar between
the flywheel fins when loosening the
flywheel nut. This can crack the fins
which may fly off when the engine is
running.
Whenever the flywheel retaining
screw is removed on KT series en-
gines, the flywheel washer should be
replaced. This is a new service proce·
dure and must be performed to ensure
joint integrity.
12. Use a flywheel puller to remove the flywheel
from the crankshaft (see Figure 7·2).
Flywheel-Inspection
Inspect the flywheel for cracks, and the flywheel
keyway for damage. Replace flywheel if cracked.
Replace the flywheel, the crankshaft, and the key
if flywheel key is sheared or the keyway damaged.
Inspect ring gear for cracks or damage. Kohler no
longer provides ring gears as a serviceable part.
Replace flywheel if the ring gear is damaged.
13. Remove the alternator stator. (Statoris exposed
when flywheel is removed.)
Figure 7·2. Flywheel Removal
Identify Engine Sides
14. To ensure proper reassembly, it is necessary to
identify one side of the engine from the other.
The #1 side of the crankcase is the side with the
cylinder barrel closest to the flywheel.
With a marking pen, paint, or chalk, mark the
crankcase halves and cylinder heads #1 side
and #2 side (see Figure 7-3).
CAUTION: Do not use a metal stamp to mark
crankcase as damage to crankcase
may result.

Figure 7-3. Marking The Case Halves For Identification
15. Remove the starter motor.
NOTE: On earlier models the starter end cap
will come loose when the starter is discon·
nected from the engine, this could cause the
brush springs to fall out of the starter. To
prevent this, always hold the end cap firmly
against the starter frame when removing the
starter motor.
16.
Remove the breather assembly from the #1
valve chamber and the valve cover from the #2
valve chamber.
17. Disconnect the breaker points and remove the
breaker push rod.
18. Remove
the fuel pump.
CYLINDER HEADS, BARRELS,
VALVES
AND PISTONS
1. Remove the cylinder head screws and cylinder
heads.
2. Remove the cy Iinder barrels and barrel gaskets.
The cylinder barrels are identified as either #1 or
#2
by a mark already stamped into the gasket
seating surface of each valve chamber (see
Figure 7 ·4).
When removing and reinstalling cylinder barrels
make sure each barrel is assembled to the correct
crankcase side. (The #1 side of the crankcase is the
side with the cylinder barrel closest to the flywheel.)
To
simplify service requirements, and as a stan·
dardization procedure, a service replacement cylin-
der barrel with both hardened valve seat inserts
assembled is now available. It can be assembled to
either crankcase side.
