Description

New 45D4 Replacement Electronic Distributor for Vehicles with Points-based Lucas 25D4, 45D4, 48D4, 54D4 Vacuum-advance Distributors
New HS45D4 Distributor
with 3LUC4-45D Electronic Ignition
Replaces Lucas 4-Cylinder 45D Distributors
(for 12-volt, negative ground electrical systems only)
Brand New Vacuum-advance HS45D4 Distributor Replaces Most 4-cylinder Vacuum-Advance, Points-Based Lucas Distributors
Includes 3LUC4-45D electronic ignition conversion kit already installed, ready to replace your worn-out Lucas 4-cylinder, vacuum-advance distributor – Just install distributor, connect the red wire to the coil's positive (+) terminal and the black wire to the coil's negative terminal ( – ), connect vacuum hose to carburetor/throttle body and set the timing - Simple!
Zero-maintenance 3LUC4-45D electronic ignition means you won't have to fool with points and timing again – always stays in perfect tune!
Distributor is a quality reproduction of the original vacuum-advance Lucas 45D4 vacuum-advance 41427 distributor. This distributor requires a vacuum source from the carburetor or throttle body (when used with fuel injection). Uses standard Lucas 45D4 distributor cap, rotor, etc. Perfect replacement for worn-out Lucas 45D4, 48D4, 54D4 distributors.
The HS45D4 distributor is compatible with these standard Lucas parts:
Distributor: Lucas 41427, 45D4, 41630
Rotor: Lucas 54422803, DRB104C, (superior red rotor included with distributor)
Distributor Cap: Lucas 54427109, DDB108
Replaces 4-cylinder Lucas 45D4, 48D4, 54D4 Vacuum-advance Distributors
We inspect each distributor thoroughly; everything is checked, adjusted, lubricated, etc. We then set and test the advance curve on a precision distributor testing machine.
Installing the HS45D4 Distributor
Rotate the engine until the rotor is pointing at No.1 Cylinder's spark plug wire. Remove each spark plug wire from the old distributor cap, one-at-a-time, and insert it into the new distributor cap in the same location and order (cylinders 1-3-4-2, counter- or anti-clockwise).
Remove the old distributor and remove its clamp. Coat the new distributor's shaft and O-Ring with motor oil before sliding it into its hole. Look down into the engine's distributor hole to see how the distributor drive slot is oriented and turn the distributor shaft to match it. You might need to tap the distributor's rim gently to get the O-Ring started into the hole. Work the shaft down all the way, turning the rotor gently, as needed, until the distributor shaft gear settles into its slot and the rotor will no longer turn.
Turn the distributor body until the rotor points to the spark plug wire of No. 1 Cylinder. Place the cap on the new distributor. Tighten the distributor clamp enough so that the distributor can't turn on its own, but you can still turn it by hand.
Timing the HS45D4 Distributor
Use a stroboscopic timing light. Timing should be set initially to about 24° BTDC at 3,500+ RPM, vacuum hose connected. Firing order is: 1-3-4-2, counter-clockwise (anti-clockwise). The ignition timing should be checked with the engine running, using a stroboscopic timing light, ensuring optimum engine performance and economy. Paint a small line of white paint on both the reference pointer and the appropriate mark on the timing scale to make them more easily seen. With the engine running at the specified speed, the appropriate timing mark should be in line with the reference pointer. Rotate the distributor body clockwise to advance the timing, or counter-clockwise to retard it. Tighten the distributor clamp. Reconnect the vacuum line to the distributor's vacuum canister port.
This distributor requires a 12-volt, negative ground electrical system.
Coil:
A coil with 3.0 Ohms or more primary resistance must be used.
The
Bosch Black Coil
with 3.4 Ohms primary resistance is ideal for 4- and 6-cylinder ignition kits.
To measure coil primary resistance:
Label and remove all wires to coil ( + or - ). Using a common digital multimeter in the 200 Ω mode, cross the red and black leads of the Ohmmeter. Allow 10 seconds or more for the reading to settle and write down the reading. Still in the 200 Ohm mode, measure between coil’s + and - terminals. Allow a few seconds for the reading to settle, until it stabilizes. Subtract the previous reading, taken with the leads crossed, to compensate for Ohmmeter’s inherent resistance. Do not use a low-resistance coil, such as the MSD or Accel coil; they don’t have enough primary resistance for this application.
Test the charging system's maximum voltage:
If the charging system voltage, measured at the coil's + terminal, is more than 13.9 volts at any RPM level, the voltage regulator likely needs replacing or a
1.4 Ohm ballast resistor
should be wired between the coil's + terminal and the red HotSpark ignition wire. Too much voltage can damage the ignition module and other electronic components.
