The HS-HIT4 distributor is compatible with these standard Hitachi parts:

4-cylinder Hitachi L16, L18 and L20B vacuum-advance distributors

Can use standard Hitachi Rotor and Distributor Cap

Replaces 4-cylinder Hitachi L16, L18 and L20B vacuum-advance distributors

Installing the HS-HIT4 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. 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 HS-HIT4 Distributor
Use a stroboscopic timing light. Timing should be set initially to about 32° 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 Ohms or more primary resistance should be used. Stock 3+ Ohm points coil or HS34HEC high-energy coil required.

To measure coil's 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 14.2 volts at 2,500+ RPM, the voltage regulator likely needs replacing. Too much voltage can damage the ignition module and other electronic components.

HS34HEC	Hot-Spark High-Energy Coil 3.4 Ohms primary resistance 12K Ohms secondary resistance
High secondary resistance for more voltage at the plugs  Ideal for Use with Hot-Spark  4-cyl Electronic Ignition Conversion Kits with red 3-series ignition module	Heavy-duty, high-energy coil with extra turns of copper wire in the secondary windings for as much as 45,000 volts to the spark plugs - more turns of copper wire than other standard-sized canister coils. Application:   Ideal for 4-cylinder distributors. Provides more primary resistance to protect from overheating due to high-voltage or high-temperature environments. 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. In Stock:   Available:
