FLINT JUNIOR MODEL Z-18 (1927) AUTO-LITE GENERATING, STARTING AND LIGHTING SYSTEM AUTO-LITE IGNITION BATTERY:—U.S.L. Type 3-CVX-5X, 6 volt, 84 ampere hour. pares god is 96 amperes for 20 minutes. Lighting capacity is 5 amperes for 16.8 hours. The negative (—) terminal is grounded. IGNITION:—Coil Model IG-4070. Distributor Model IG-4118-A. Breaker contacts separate .020-.024 inch. Resurface contacts whenever necessary with a fine flat contact file or on a medium hard oilstone. Distributor is semi-automatic. Max- imum manual advance is 20° (engine). Automatic advance begins at 350 R.P.M. (engine). Maximum automatic advance is 20° reached at 3200 R.P.M. Breaker arm spring tension is 20 ounces. Ignition current is 1-3 amperes with engine run- ning and 3.4-5 amperes with engine stopped. Oiling:—Put 4 or 5 drops of light engine oil in the oiler on the side of the distrib- utor housing every 250 miles. Timing :—Breaker contacts begin to separate when the piston entering power stroke reaches top dead center with the spark control lever and breaker assembly in the fully retarded position. Mounting: —Distributor is mounted on the rear of the generator. To remove distrib- utor, remove the set screw and lift unit from place. Firing Order:—The firing order is 1-5-3-6-2-4. Spark Plugs:—Spark plug diameters are 74 inch. Gaps are .025 inch. STARTER:—Model MP-4102. Starter is connected to the engine through a Bendix drive. e direction of rotation is counter-clockwise, looking at the commutator end, Starter brush tension is 1/4-11/2 pounds each. Starter cranks the engine at 175 R.P.M. taking 180 amperes at 4.5 volts. Starter Data Torque R.P.M.

To remove starter, remove the mounting cap screws and slide starter forward from place. Oiling:—Put 4 or 5 drops of light engine oil in the oiler on the drive end of the starter every 1000 miles. GENERATOR:—Model GYA-4204. The direction of rotation is counter-clockwise, look- ing at the commutator end. The third brush system is used for current regulation. To adjust the charging rate, remove the generator cover band and shift the third brush. Shifting the brush in the direction of armature rotation increases the charg- ing rate and in the opposite direction decreases the charging rate. The maximum charging rate is 15 amperes reached at 1500 R.P.M of the generator or 25 M.P.H.
