2. Making sure any spacers/shims are correctly
installed, place the pre-combustion chamber into
the cylinder head with the glow plug opening
directed toward the glow plug bore.
NOTE: To simplify installation/orientation of the
pre-combustion chamber, install the chamber on
the removal tool; then place into the head. Remove
the tool after completing step 3.
3. Insert the pre-combustion chamber alignment tool
into the glow plug bore while slightly shifting the
chamber until the alignment tool properly engages
the opening in the chamber; then completely
thread the tool in and tighten securely.
4. If the removal tool was utilized, remove it from
the chamber. Install the pre-combustion chamber
ring nut and using the Allen-head tool, tighten the
ring nut to an initial torque of 10.0 kg-m (72 ft-lb);
then to a final torque of 18.0 kg-m (130 ft-lb).
