Once the distributor is removed, the engine should NOT be turned or moved out of position. Should this occur, please refer to the engine rotated installation procedure.
- Disconnect the negative battery cable.
- Disconnect the distributor wire(s) at its harness.
- On the 4A-F engines, disconnect the vacuum advance hoses.
On some models the distributor wires are part of the cap and can not be separated.
- Remove the distributor cap. Label and disconnect the wires from the cap. On some engines it will be necessary to use a flat bladed tool to lift up the lock claw and disconnect the holder from the cap.
- Carefully note the position of the distributor rotor relative to the distributor housing (also note position of distributor to the engine assembly); a mark made on the casing/housing will be necessary for reassembly. Use a marker or tape so the mark doesn't rub off during handling of the case/housing.
- Remove the distributor hold-down bolts.
- Carefully pull the distributor from the engine assembly. Remove the O-ring from the distributor shaft.
Engine Not Rotated
- Install a new O-ring with lightly coated engine oil onto the distributor shaft.
- If the engine has not been moved out of position, align the rotor with the mark you made earlier and reinstall the distributor, aligning the mark made for distributor housing to engine assembly. Position it carefully and make sure the drive gear engages properly within the engine.
- Install the hold-down bolts.
- Install the distributor cap.
- Install the wiring to the distributor. On the 4A-F engine, attach the vacuum hoses.
- Connect the negative battery cable.
- Warm up the engine to reach operating temperature and adjust the timing.
If the engine has been cranked, dismantled or the timing otherwise lost while the distributor was out, proceed as follows:
- Remove the No.1 spark plug.
- Place your finger over the spark plug hole and rotate the crankshaft clockwise to TDC (Top Dead Center). Watch the timing marks on the pulley; as they approach the ZERO point, you should feel pressure (compression) on your finger. If not, turn the crankshaft another full rotation and line up the timing marks.
The spark plugs are in deep wells; use a screwdriver or equivalent to fill the hole and feel the compression.
- Temporarily install the rotor in the distributor without the dust cover, if equipped. Turn the distributor shaft so that the rotor is pointing toward the No. 1 terminal in the distributor cap. On the 4A-GE engine, align the drilled mark on the driven gear with the groove of the housing. On the 4A-F, 4A-FE and 7A-FE engines, align the cutout of the coupling with the line of the housing.
- Align the matchmarks on the distributor body and the engine block which were made during removal. Install the distributor in the block by rotating it slightly (no more than one gear tooth in either direction) until the driven gear (lubricate drive gear with clean engine oil) meshes with the drive.
- Temporarily tighten the distributor hold-down bolts.
- Remove the rotor and install the dust cover, if equipped. Replace the rotor and the distributor cap.
- Reconnect all electrical wiring and vacuum hoses if equipped. Install the No. 1 spark plug and all plug wires if necessary.
- Warm the engine and check ignition timing. Tighten the distributor hold-down bolts.
