c. Disassembly. Refer to figure 3-33 and disassem-

ble the distributor far enough to replace rotor and

contacts as follows:

(1) Release cap retaining springs (8) and remove

cap (l), rotor (2), and dust cover (3), from housing

(9).

(2) Remove breaker lever (6) from pin. Remove

two screws (5) and remove contact assembly (4).

(3) Disconnect wire and remove screw (11) and

lock washer (10) and remove capacitor (7).

d. Inspection and Repair.

(1) Clean all parts thoroughly and replace any

damaged or worn parts. Do not use solvent or de-

greasing compound on cap, dust cover, rotor, capa-

citor, insulator, or housing.

(2) Clean slightly worn or pitted contact points

with a few strokes of a clean fine-cut file. Replace

points if worn or badly pitted.

(3) Check breaker lever rubbing block for ex-

cessive wear.

(4) Check capacitor for leakage. Replace capaci-

tor if unable to test.

(5) Check distributor cap and rotor for cracks,

burned or pitted contacts, and carbon streaks.

e Assembly. Refer to figure 3-33 and assemble

distributor as follows:

(1) Install capacitor (7) and secure with screw

(11) and lock washer (10). Connect capacitor wire to

stud.

(2) Install contact assembly (4) and secure with

screws (5). Do not tighten lock screw.

(3) Install breaker lever (6) on pin.

(4) Install dust cover (3) and rotor (2).

f. Installation Refer to figure 3-32 and install dis-

tributor as follows:

(1) Install ignition distributor in drive assembly.

(2) Secure distributor and advance arm with

screws and lock washers. Install cap on distributor

and secure with springs.

Note. Before installing spark plug cables and high tension

cable, adjust point gap (g below).

(3) Install spark plug cables and high tension

cable in distributor cap sockets.

(4) Connect coil primary wire to terminal on dis-

tributor.
