It is necessary to place the No. 1 cylinder in the firing position to correctly install the distributor. To locate this position, the ignition timing marks on the crankshaft front pulley are used.
Remove the No. 1 cylinder spark plug. Turn the crankshaft until the piston in the No. 1 cylinder is moving up on the compression stroke. This can be determined by placing your thumb over the spark plug hole and feeling the air being forced out of the cylinder. Stop turning the crankshaft when the timing marks indicate TDC
Oil the distributor housing lightly where the distributor bears on the cylinder block.
Install the distributor so that the rotor, which is mounted on the shaft, points toward the No. 1 spark plug terminal tower position when the cap is installed. Of course you won't be able to see the direction in which the rotor is pointing if the cap is on the distributor. Lay the cap on the top of the distributor and make a mark on the side of the housing just below the No.1 spark plug terminal plug terminal. Make sure that the rotor points toward that mark when you install the distributor. On the VG30i, align the mark on the distributor shaft with the protruding
mark on the housing.
When the distributor shaft has reached the bottom of the hole, move the rotor back and forth slightly until the driving lug on the end of the shaft enter the slots cut in the end of the oil pump shaft and the distributor assembly slides down into place.
When the distributor is correctly installed, the breaker points should be in such a position that they are just ready to break contact with each other or a lobe of the reluctor is aligned with the stator contact. This is accomplished by rotating the distributor body after it has been installed in the engine. Once again, line up the marks that you made before the distributor was removed from the engine. On the VG30i, the distributor rotor should be in the 11:25 o'clock position (between 11 and 12 o'clock).
- Install the distributor hold-down bolt.
- Install the spark plugs.
- Install the cap, primary wire, and vacuum line(s).
- Install the spark plug leads. Consult the marks made during removal to be sure that the proper lead goes to each plug. Install the high tension wire if it was removed.
- Start the engine. Check the timing and adjust it if necessary.
