Brand New Vacuum-advance HS25D4 Distributor Replaces Most 4-cylinder Vacuum-Advance, Points-Based 25D Lucas Distributors

Includes 3LUC4-25D 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 3LUC4-25D 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 25D4 vacuum-advance 41199 distributor. This distributor requires a vacuum source from the carburetor or throttle body (when used with fuel injection). Uses standard Lucas 25D4 distributor cap, rotor, etc. Perfect replacement for worn-out Lucas 23D4 and 25D4 distributors.

The HS25D4 distributor is compatible with these standard Lucas parts:

Distributor: Lucas 41199, 25D4
Rotor: Lucas 400052, (superior red rotor included with distributor)
Distributor Cap: Lucas Top-entry cap: 54417214, DDB106 or Side-entry cap: Lucas 54412480

Replaces 4-cylinder Lucas 23D4 and 25D4 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 HS25D4 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 HS25D4 Distributor
Use a stroboscopic timing light. Timing should be set initially to about 24° BTDC at 3,500+ RPM, vacuum hose disconnected and plugged. 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 (earth) electrical system.

Coil: A coil with 3.0 Ohms or more primary resistance must be used. Stock Lucas 3.0+ Ohm points coil or HS34HEC high-energy coil required. The Beru Germany Blue Coil with 3.3 Ohms primary resistance is ideal for 4- and 6-cylinder ignition kits.

To measure 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 multimeter’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 positive terminal, is more than 14 volts at 2,500+ RPM, the voltage regulator likely needs replacing. Too much voltage can damage the ignition module and other electronic components.

Produces strong, blue spark at the plugs

 Ideal for Use with Hot-Spark  4- and 6-cyl Electronic Ignition Conversion Kits with red 3-series ignition module

Heavy-duty, high-energy coil sends as much as 45,000 volts to the spark plugs - Produces strong, blue spark at the plugs.

Application:

 

Ideal for 4- and 6-cylinder distributors. Provides more primary resistance to protect from overheating due to high-voltage or high-temperature environments. No external ballast resistor required.

Designed specifically to produce maximum spark when used with Hot-Spark red electronic ignition conversion kits  (red ignition module). Also excellent for points-based distributors - high primary resistance helps reduce points burning, pitting.

 

 

Epoxy-filled canister (not oil-filled) to withstand high-vibration environments

Rugged, mirror-polished  case - won't chip or peel like chrome-plated  coil canisters.

Standard 56mm (2.2 in.) coil diameter - fits stock coil clamps.
