BREAKER POINT AND SPARK PLUG GAP
It is very important that spark plugs and breaker points be adjusted to the same limits used at the factory (see Fig. 1117). Please see that this practice is followed in your shop.

Distributor
Several instances have been reported of dealers increasing the width of the plate lever notch in the distributor body in endeavoring to increase the travel of the plate lever. This is exceedingly poor practice and must be discontinued at once. The plate lever notch in the distributor body is accurately machined to permit the lever …
DISTRIBUTOR CAM SHAFTS MUST HAVE PIN HOLES
A quantity of the distributor cam shafts A-12178 were shipped less the .128/.132 drilled pin hole. Please check your stock and if you have any of these shafts that do not have this .128/.132 hole drilled in the shaft, return them to your branch for drilling. (See Fig. 957.) We prefer to have the Branch …
CONNECTING HIGH TENSION WIRE TO COIL
When connecting the high tension wire to the coil, extreme care must be taken to make certain that the wire goes all the way into the coil until it makes a good contact. (See view at left side of Fig. 920.) If the high tension wire does not make a good contact in the coil, …
Distributor
Contacts on the distributor body and on the rotor should be cleaned with very fine sandpaper. This will remove any corrosion on the contacts. Corrosion sets up a high resistance in the secondary circuit. Check the breaker point gap. The gap should measure between .018 and .022.
CHECK BREAKER POINT GAPS
When a new car comes in for inspection, always be sure to check the breaker point gap. This is important. During the first few hundred miles a new car is driven, the contact point on the fiber block on the breaker arm assembly slightly wears until a hard glaze forms on the block. This glaze …
Breaker Points
The distributor breaker points should occasionally be checked to see that the points are clean, smooth and meet squarely. A point which is in good condition has a dull frosted appearance. Whenever necessary to clean the points use a fine oil stone-never a file. If badly pitted new points should be installed. The gap between …
RETARD SPARK LEVER WHEN STARTING
Owners should be instructed to be sure to retard the spark lever when starting the engine. Broken or bent starting motor armature shafts can invariably be traced to failure to retard the spark lever when starting engine.
Adjusting Breaker Contact Points
Correct adjustment of breaker contact points and correct ignition timing play such an important part in the satisfactory operation of an engine, that it is absolutely necessary that every mechanic thoroughly understand the correct procedure. So that there may be no misunderstanding, we are again describing these operations. The gap between the breaker points is …
Breaker Arm Assembly
((588)) As an added protection against car theft, the distributor breaker arm spring is now riveted around the breaker arm spring stud (see A, Fig. 588), the thickness of the head of the stud increased and the stud case hardened. These changes add two more parts to the breaker arm assembly, namely, breaker arm spring …
Lubricating
When lubricating the car do not overlook the oil cup on the side of the distributor body. Oil should be added every 500 miles. Sufficient oil should be added to reach the level of the oil pump. Regular engine oil can be used for lubricating distributor.

Distributor breaker points should occasionally be checked to see that the points are clean, smooth, and meet squarely. A point which is in good condition has a dull frosted appearance.
