Dodge B-I-B 1948 - Spark Plug Adjustment; Lighting System

intake valve open at that point. With No.6 piston at the top of the
exhaust stroke, No. 1 piston will be at the top for the firing stroke.
Turn distributor shaft in a clockwise direction until the. rotor points
to the cap post to which No. 1 spark plug wire is connected, and
with the breaker points just starting to open. Install the distributor
and adjust timing as outlined in the foregoing.
The firing
order of the engine is 1-5-3-6-2-4.
SPARK PLUG ADJUSTMENT
The gap between the electrodes of each spark plug should be
.025 inch. The gap will gradually increase with use and should be
adjusted by bending the outside electrode. Measurement of the
gap can most accurately be made with a wire rather than a flat
feeler gauge.
For efficient and economical operation, all spark plugs should
be replaced every 10,000 miles with the same type as the original
equipment.
CLEANLINESS OF IGNITION SYSTEM IMPORTANT
A film of dirty oil and water gradually accumulates on parts of the
engine which cannot be avoided. It is essential, for best engine per-
formance, that exposed parts of the ignition system be kept clean
and dry.
The porcelains
of the spark plugs and the outside of the distribu-
tor
cap, as well as the exposed end of the spark coil, should be kept
clean at all times. The wires leading from the distributor to the spark
plugs and spark coil should also be clean and free from dirt,
water and oil.
LIGHTING SYSTEM
The lighting circuit of your Dodge truck is protected by a 30-ampere
fuse located at the back of the light switch. In case a short circuit
develops in the lighting system, the fuse will automatically blow
before damage occurs.
HEADLIGHTS
The headlight lens, bulb and reflector are built up into one water-
proof and dustproof prefocused unit which is replaceable as a unit
