DISTRIBUTOR The distributor is mounted on the right side of the engine and is driven by a gear on the camshaft. One of the distributor functions is to interrupt the current flow through the primary winding of the ignition coil, thus causing the coil to produce voltage high enough to jump the gap at the spark plugs at the desired instant during the compression stroke. As engine speed increases, the spark must occur earlier at the spark plugs. This is accomplished by an automatic spark advance that is controlled by centrifugal weights in the distributor. This is necessary to allow the fuel air mixture sufficient time to ignite and burn. The centrifugal weights, advance the breaker cam to give a predetermined variation in spark advance for different engine speeds. An accurate measurement of spark timing at any given engine rpm can only be determined on the engine by use of a timing light.

2. Lift the breaker dust cover, retainer, seal and gasket from the distributor as an assembly. 3. Remove the nut and lockwasher that connects the condenser lead and primary conductor to the breaker points.

4. Remove the screws that attach the breaker points and condenser to the breaker plate. S. Remove the two screws that attach the breaker plate to the distributor base. Lift the plate from the base.

6. Remove the nut, lockwBsher, insulator bushing, insulator, conductor, and brass screw from the distributor base.

7. Remove the snap ring that secures the cam and weights to the distributor shaft. Lift the cam and weights from the shaft.

A. Removal

8. File the upset end of the rivet that secures the distributor gear to the shaft until it is flush with the gear. Remove the rivet with a punch.

1. Disconnect the primary wire at the distributor. 2. Unsnap the two distributor cap bale clamps and lift the distributor cap off the distributor.

9. Remove the gear from the shaft with Remover 12390-C-3, as shown in Figure 5.

S. Scribe a mark on the dust cap opposite the rotor contact. Note the position of the primary terminal on the distributor so that it may be located in the same approximate position when installing the distributor.

10. Carefully pry the oil seal out of the lower end of the distributor base. 11. With the distributor base in the inverted posi. tion, drive the bushing out of the base with Distributor Shaft Bushing Remover 12132-B-l, as shown in Figure 6.
