Installation
1. Clean the distributor cam thoroughly.
2. Apply a light film of distributor cam lubricant C4AZ- 19D530-
A on the cam. Do not use any type of oil.
3. Apply a few drops of oil to the distributor oil felt.
4. Position the breaker points in the distributor and install retain-
ing screw.
5. Position condenser and terminal assembly to distributor and
install retaining screw.
6. Connect primary wire to coil and breaker point primary lead to
condenser terminal.
7. Install rotor and distributor cap.
SPARK PLUG WIRE
When removing the wires from the spark plugs or distributor
cap, grasp, twist and pull the moulded cap only. Do not pull on the
wire because the wire connection inside the cap may become
separated or damaged.
Removal
1. Disconnect the wires from the spark plugs and distributor cap.
2. Lift the wires from the clip on the valve rocker arm cover and
remove the wires.
3. Remove the coil high tension lead.
Installation
1. Insert each wire in the proper socket of the distributor cap
(Figure 10). Be sure the wires are forced all the way down into
their sockets.
2. Remove the wire retaining bracket from the old spark plug
wire set and install it on the new set in the same relative
position. Install the wires in the clip on the valve rocker arm
cover. Connect the wires to the proper spark plugs. Install the
coil high tension lead.

SPARK PLUGS
Removal
1. Disconnect the wire from each spark plug by grasping, twist-
ing and then pulling the moulded cap of the wire only. Do not
pull on the wire because the wire connection inside thecap
may become separated or damaged.
2. After loosening each spark plug one or two turns, clean the
area around each spark plug port with compressed air, then
remove the spark plugs.
After cleaning, the electrodes must be dressed with a small
file to obtain flat parallel surfaces on both the center and side
electrodes. Set the spark plug gap to specifications by bending the
ground electrode. All spark plugs new or used should have the
gap checked and reset as required.
Installation
1. Install the spark plugs and torque each plug to specification.
2. Connect the spark plug wires.
Removal
1. Remove the distributor cap and position clear of distributor.
2. Disconnect the vacuum line from
the
distributor.
3. Disconnect primary lead from the coil.
4. Position engine at TDC on No. 1 cylinder. The notch (TDC)
on the crankshaft pulley should be lined up with the 0 mark
(TDC) on the front cover and the rotor should be lined up with
the scribe mark on the distributor housing (Figure 13).
5. Remove distributor retaining bolt and remove distributor.
Mark rotor position on distributor housing to assist in
installation.

B- Scribe Mark
C - Timing Marks
Installation
1. Check that the engine is at TDC on No. 1 cylinder.
2. Align rotor with mark made on distributor housing.
3. Install distributor into block and install retaining bolt. Rotor
should be aligned with scribe mark at this time (Figure 13).
4. Install distributor cap an3 connect primary lead to coil.
5. Check and adjust initial ignition timing.
NOTE: If timing cannot be adjusted with retaining bolt,
position bolt in center of slot and tighten. Loosen distribu-
tor clamp retaining bolt (Figure 14) and adjust initial
timing to specification. Tighten clamp retaining bolt. DO
NOT OVER-TIGHTEN (25-30 inch pounds torque).
