OLD DISTRIBUTOR REMOVAL

Step 1

Disconnect the distributor plugs from the distributor module.

Step 2

Locate the spark plug wire on the original distributor cap that the engine

timing is set from. See a service manual for these locations. Mark the

distributor cap and the distributor housing, in line with this spark plug wire

position on the distributor cap.

Step 3

Turn the engine crankshaft in e direction of rotation until the timing mark lines

up with the top dead center (TDC) mark on the timing tab. See a service

manual for these locations.

NOTE: Removing the spark plugs may make it easier to turn the crankshaft.

Step 4

Remove the distributor cap from the distributor. Do not remove the spark plug

wires or coil wire at this time. The rotor blade should point to the mark made

on the distributor housing (from Step 2). If it is not, turn the engine crankshaft

in the direction of rotation one full turn (repeating Step 3) until the timing

mark lines up (again) with the TDC mark on the timing tab.

NOTE: Once you are finished with step 4, DO NOT turn the crankshaft until the

new distributor is installed.

Step 5

Note the direction the rotor is pointing. Note the direction the distributor

module is facing. Remove the distributor, hold down clamp and remove the

distributor from the engine.

PERFORMANCE REPLACEMENT

DISTRIBUTOR INSTALLATION

Step 1

Remove the distributor cap.

Step 2

Place the distributor in the engine with the rotor pointing in the same general

direction as the original distributor.

NOTE: The distributor must be fully seated into the engine. It may be

necessary to turn the oil pump drive, or turn the engine crankshaft in the

direction of rotation two full turns until the timing mark lines up (again) with

the TDC mark on the timing tab, to allow the distributor to seat fully.

Step 3

Rotate the distributor housing until distributor module is facing the same

general direction as the original distributor was facing.

This will generally give timing close enough for starting purposes. Put the

distributor hold down clamp in place and tighten slightly, leaving it loose

enough to turn the distributor. Make a mark on he distributor housing where

the rotor points.

Step 4

Install the distributor cap. Remove the spark plug wire on the original

distributor cap that the engine timing is set from, and install it into the

distributor cap post above the mark on the distributor housing where the rotor

had pointed. Continue installing each remaining spark plug wire, one at a time,

from original distributor cap to the distributor cap in the same sequence.

WIRING PROCEDURE

Connect the distributor plugs into me distributor module.

STARTING ENGINE

CAUTION: Be sure all tools, wires and miscellaneous objects are clear of

moving engine parts and extreme heat before starting the engine.

Step 1

Recheck all wires and connections to make sure they are correct. Check and

clean, or replace spark plugs. If replacing spark plugs, use types

recommended by the engine manufacturer.

Step 2

Connect a timing light. Find the area with the best view of the timing marks.

Step 3

Check your service manual ignition timing procedures and settings. Start the

engine. If it fails to start, rotate the distributor in small increments clockwise

or counter-clockwise until engine starts. Do not exceed more than ten degrees

of distributor housing rotation in either direction.

IMPORTANT: Follow ignition timing procedures outlined in your service

manual. Some vehicles require putting the ignition timing in bypass mode

by disconnecting a wire connector as part of the ignition timing procedure.

Step 4

Set timing as recommended by engine manufacturer and outlined in your

service manual, then tighten distributor hold down clamp. Make sure timing is

still correct. If timing has moved, repeat this procedure.
