CADILLAC MODEL 314. SERIAL NUMBERS 100,001 UP (1926) DELCO GENERATING, STARTING AND LIGHTING SYSTEM DELCO IGNITION BATTERY:—Exide, Type 3-LXRV-15-2G, 6 volt, 130 ampere hour. The starting capac- ity is 137 amperes for 20 minutes. Lighting capacity is 5 amperes for 26 hours. The positive (+) terminal is grounde IGNITION.—Coil Model 2189. Distributor Model 5281. Breaker contacts separate .025 inch. They are made of tungsten. When the condition of the contacts affects the ignition, remove and resurface on a medium hard oilstone or with a fine, flat jew- elers’ file. The tension of the contact arm spring should be 16-20 ounces. Manual advance is 18-22°. Automatic advance begins at 600 R.P.M. and reaches a max- imum of 30° at 2800 R.P.M. Oiling:—Put 8 or 10 drops of light engine oil in the oiler on the side of the distrib- utor housing every month or each 1000 miles if the car is driven more than 1000 miles in a month. Mounting:—Distributor is mounted between the cylinder banks and is driven by spiral gears from the cam shaft. To remove unit, remove hold down screw and lift from position. Timing.—One set of breaker contacts begins to separate when piston No. | on com- pression stroke reaches a position at which the flywheel marking [G/A-I/5 is op- posite the indicator on the flywheel case. This is approximately 1 27/32 inches before top dead center. The manual advance lever must be in the fully advanced position. The other set of contacts open when the engine has turned over 90° (or 45° of the distributor). In this position the flywheel marking IG/A-2/6 is opposite the indicator. Firing Order:—The firing order is 1L-4R-4L-2L-3R-3L-2R-IR. Spark Plugs:—Spark plug diameters are 74 inch. Gaps are .025 inch. STARTER:—Model No. 314. Starter is connected to the engine through a pinion shift incorporated in the starting pedal. The direction of rotation is counter-clockwise, looking at the commutator end. Starter cranks the engine at 104 R.P.M. taking 140-150 amperes. Starter brush tension should be 2!4-2’4, pounds each. Starter Data Torque R.P.M. Volts Amperes 0 if | Ses UD So Seid Freesat tee peer.

To remove, loosen set screw in steering column and remove starting pedal button and accelerator pedal. Then remove toe boards and disconnect hand throttle rod and foot throttle rod. Remove three hold down screws and lift starter from place. Oiling:—Self-lubricating bearings are used. They require no attention. GENERATOR :—Model No. 315. The direction of rotation is counter-clockwise, look- ing at the commutator end. Generator current regulation is by the third brush system. To adjust the generator output, shift the third brush mounting plate by turning the hexagonal nut on the outside of the generator end plate. Turning the nut in a clockwise direction increase the charging rate and in the opposite direc- tion decreases the charging rate. The maximum output is 15-17 amperes reached at 1000 R.P.M. of the generator armature. Generator Data fee Volts Ce re er ane meeeesseeeens (S tt DASH LAMP CADILLAC MODEL 314.
