REPAIR INSTRUCTIONS, PART 2
17. Using the brush, clean the copper sleeve
opening in the cylinder head.

Figure 403 — Cleaning Injector Tip Bore
The injector bore sealing tool must be used to
prevent debris from entering the fuel passage.
When replacing the copper sleeves, it is
important to check that the sleeve bore in the
cylinder head is free from any carbon deposits or
other residue (i.e., pieces of O-ring, etc.) before
installing a new copper sleeve. Reclean if
necessary.
18. Using the chip vacuum, remove all debris
from the copper sleeve bore.
Do not attempt to blow away debris using
compressed air. Doing so can result in eye injury.
19. Remove the injector bore sealing tool from
the cylinder head. Using the chip vacuum,
remove any remaining debris.
Copper Sleeve Installation
1. Ensure the piston is at the lowest position in
the cylinder. If not, use the flywheel turning
tool to place the piston at its lowest position.
404
Figure 404 — Flywheel Turning Tool, Installed
This is to ensure that the copper sleeve
installation tool does not damage the piston due
to tool length.
2. Before installing the copper sleeve, inspect it
to ensure that it is the correct part. The
correct sleeve is identified by two concentric
circular grooves machined into the top
surface.
