REMOVAL



See Figures 1 through 8

You will need a new O-ring for installation of the distributor.

  1. Disconnect the battery ground cable.
  2.  
  3. Disconnect the retaining clips or screws and pull the distributor cap and seal off the distributor.
  4.  
  5. Position the cap and wires away from the distributor. You may find this procedure easier if you label and remove all spark plug cables and the ignition coil cable from the distributor cap.
  6.  
  7. Matchmark the location of the distributor on the cylinder block. A good place to do this is near where the mounting bolt passes through the slot.

  1. Disconnect and label the vacuum advance line, if so equipped.
  2.  
  3. Disconnect and label the distributor wiring connector.
  4.  
  5. Matchmark the relationship between the tip of the distributor rotor and the distributor body.
  6.  

Later model distributors have alignment marks on the flange, housing and gear. Aligning these marks is more accurate than aligning the rotor with a homemade mark.

  1. Remove the mounting nut or bolt and pull the distributor carefully out of the engine. Note the direction and degree to which the rotor turns as you pull it out. Mark the location of the rotor after it has turned, also.
  2.  
  3. Remove the old O-ring from the distributor shaft and replace it with a new one before reinstalling the distributor.

INSTALLATION



Engine Not Disturbed

This condition exists if the engine has not been rotated while the distributor was removed.

  1. Position the distributor so that the distributor and block matchmarks are lined up.
  2.  
  3. Position the rotor so that it lines up with the matchmark on the distributor body after the distributor was pulled part way out.
  4.  
  5. Insert the distributor into the block until the gears at the bottom engage and begin turning the rotor. If there is resistance, turn the rotor back and forth slightly so the gears mesh. Once the gears engage and inserting the distributor causes the rotor to turn, push the distributor in until it seats and the rotor is lined up with the first mark made on the body.
  6.  
  7. Install the distributor mounting bolt and tighten it finger-tight.
  8.  
  9. Reconnect the vacuum advance line, if so equipped and distributor wiring connector, and reinstall the gasket and cap.
  10.  
  11. Reconnect the negative battery cable.
  12.  
  13. Adjust the ignition timing as described in Engine Performance and Tune-up .
  14.  
  15. Tighten the distributor mounting bolt securely.
  16.

Engine Disturbed

This condition exists when the engine has been rotated with the distributor removed.

  1. If the engine has been rotated while the distributor was out, you will have to first put the engine on No. 1 cylinder at Top Dead Center (TDC) of the compression stroke. You can either remove the valve cover or No. 1 spark plug to determine engine position.
  2.  

Rotate the engine with a socket wrench on the nut at the center of the front pulley in the normal direction of rotation. Either feel for air being expelled forcefully through the spark plug hole or watch for the engine to rotate up to the top center mark without the valves moving (both valves will be closed or all the way up). If the valves are moving as you approach TDC or there is no air being expelled through the plug hole, turn the engine another full turn until you get the appropriate indication as the engine approaches TDC position.

  1. Start the distributor into the block with the matchmarks between the distributor body and the block lined up.
  2.  
  3. Turn the rotor slightly until the matchmarks on the bottom of the distributor body and the bottom of the distributor shaft near the gear are aligned.
  4.  
  5. Insert the distributor all the way into the block. If you have trouble getting the distributor and camshaft gears to mesh, turn the rotor back and forth very slightly until the distributor can be inserted easily. If the rotor is not lined up with the position of No. 1 plug terminal, you'll have to pull the distributor back out slightly, shift the position of the rotor appropriately, and then reinstall it.
  6.  
  7. Align the matchmarks between the distributor and block.
  8.  
  9. Install the distributor mounting bolt and tighten it finger-tight.
  10.  
  11. Reconnect the vacuum advance line, if so equipped and distributor wiring connector, and reinstall the gasket and cap.
  12.  
  13. Reconnect the negative battery cable.
  14.  
  15. Adjust the ignition timing as described in Engine Performance and Tune-up .
  16.  
  17. Tighten the distributor mounting bolt securely.
