cylinder head.
 NOTE: Non-caustic solvents may be used to assist
in carbon removal. Dry with compressed air.
! WARNING
Always wear safety glasses when working with com-
pressed air.
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.
