Disassembly, Inspection and Assembly

Distributor Components:

DISASSEMBLY
- Remove distributor cap, if it has been dismounted assembled with housing.
- Remove rotor and cap seal.

Removing Ignitor:

- Remove igniter fastening screws and take out igniter.

Removing Pick-Up Coil:

- Remove pickup coil screws and then take out pickup coil together with igniter.
- Remove E-ring and screw and then pull out vacuum controller.

Removing Base Plate:

- If necessary, remove base plate screws with washers and then take out base plate assembly.

NOTE: Base plate clips have specific location for housing grooves.

INSPECTION
Centrifugal Advancer

Checking Centrifugal Advance:

- Check advancer for rust or abnormal wear.
- Check shaft for looseness by turning it by hand.
- If any abnormality is found in the above inspection, replace as housing assembly.

NOTE: If rust is found in housing inner parts, check breather holes in housing and distributor cap.

Base Plate

Checking Base Plate:

- Check plate bearing for smooth rotation. If any abnormality is found, replace it as housing assembly. Do not wash or disassemble it.

Pickup Coil (Signal Generator)

Dust Cover, Red And White Wires:

- Remove dust cover from igniter.
- Disconnect red and white wires from igniter.

Measuring Pick-Up Coil Resistance:

- Connect an ohmmeter to red and white wires, and measure pickup coil resistance. The pickup coil resistance is not within 130 - 190 ohms. If the resistance is not within specification, replace pickup coil.

Connecting Red And White Wires To Ignitor:

- After checking, connect the red and white wires to igniter as shown, and then install dust cover.
- Lightly install flange bolts and prepare for ignition timing adjustment.
- Check to make sure that rotor is in good condition and inserted in shaft securely.
- Inspect distributor cap and clean or replace as required.
- Make sure that distributor cap seal is placed properly and install cap, and then fasten it with screws.
- Connect vacuum hoses with vacuum controller.
- Connect distributor lead coupler.
- Check and adjust ignition timing.

Reassembling Distributor:

ASSEMBLY
- Reverse procedure to assemble with the following notes.
^ Align base plate clips with housing grooves when installing.
^ When installing pick-up coil, use screws with lock and flat washers.
^ Adjust signal rotor air gap.
^ After tightening pick-up coil screws, recheck base plate for smooth rotation by turning pick-up coil and releasing it.
^ Check to make sure pick-up coil and tooth are free from metal particles.
