10. Tighten the set screw of the extractor tool to
secure the bolt. Make sure that the set screw
is seated against the flat part of the extractor
bolt.
11. Place the extractor tool with the bolt into the
injector bore. Make sure the nut on the
spindle is backed off so that the threaded
end can be completely installed through the
copper sleeve tip. Hand tighten until the bolt
bottoms out in the sleeve.

Figure 398 — Extractor Tool Installation
Make sure the extractor bolt is threaded
completely into the copper sleeve before
attempting to remove it or the tip of the sleeve
may break off as it is removed. This broken
sleeve tip can seriously damage the piston,
valves or turbocharger.
12. While holding the top of the tool stationary,
turn the large nut clockwise to extract the
copper sleeve.

Figure 399 — Copper Sleeve Extraction
When the copper sleeve is removed, make sure
that the extractor bolt is extended at least one
thread beyond the copper sleeve. If not, make
sure that no part of the copper sleeve has broken
off and fallen into the cylinder.
Do not use air tools to remove copper sleeves, or
damage to the injector bore can result.
13. Remove the two sealing rings from the fuel
passage. Using the chip vacuum, remove
any remaining debris from the injector bore.
