DISASSEMBLY OF THE ENGINE

During repair operations, when using compressed air,
wear eye protection.

DISASSEMBLY AND REASSEMBLY

Besides disassembly and reassembly operations this chapter
also
includes checking and setting specifications, dimensions, repair
and operating instructions. Always use original KOHLER spare
parts for repair operations.

Removing the injector

Slacken off the fuel delivery pipe, remove the fixing bracket and
take out the tube.
Remove the injector by levering it out with a screwdriver, as
indicated in fig. 1.

Removing the injection pump

Mark the position of the injection pump in relation to the engine
casing (if this has not already been done).
Remove the injection tube and take out the fuel pipes.
The pump can only be removed when the stop lever has been
turned to the stop position. To do this, the pump must be pressed
towards the housing as shown in fig. 2.

Flywheel extraction

Remove the fuel tank, the air conveyor and flywheel nut.
Use extractor cod. 00365R0020, as shown in figure 3.
During the demounting phases, pay particular attention to
prevent the flywheel from dropping as this could seriously
injure the operator.
Wear protective goggles when removing the flywheel ring.
IMPORTANT: Do not tap the end of the extractor when
removing the flywheel.

Removing the cover on the timing system side

Slacken off the screws around the perimeter of the cover on the
timing system side. Split the cover from the engine casing by
levering with a screwdriver in the points indicated in fig. 4.
Warning: to prevent damage to the main bearings, it is
advisable to demount the cover from the timing system
side with the engine cold.
