SPARK PLUG INSTALLATION

        INSTALLATION INSTRUCTIONS
               Ref : CMI SIL 03-2C
        Install spark plugs as follows, in addition to the instructions provided by the spark plug manufacturer.
1. Handle spark plug leads with clean, dry hands.
2. Adjust the spark plug electrode to the gap recommended by the manufacturer.
3. Always install spark plugs with new copper gasket.
4. Sparingly apply anti-seize to the spark plug threads. DO NOT APPLY ANTI-SEIZE
TO THE FIRST ROW OF THREADS.
5. Always use a six point deep well socket to install spark plugs.
6. Thread spark plug by hand into cylinder to within one or two threads of the gasket. If this is not possible, cylinder head threads or spark plug threads need to be cleaned.
7. Torque spark plugs to 300 - 360 in. lbs using a calibrated torque wrench.
8. Before installing the spark plug lead terminal, wipe it clean using a lint-free cloth moistened with isopropyl alcohol. Once dry, apply CMI Part Number 10-400533 (Miller-Stephenson MS -122AD) to the terminal insulator.
9. Ensure the inside of spark plug barrel is clean and dry.
10. Insert spark plug lead connector into the spark plug barrel with fingers in a straight  line with the spark plug.
11. Screw B-nut into place until finger tight.
12. Tighten the B-nut to the torque specified in Table 1 while holding the spark plug lead ferrule stationary
