Lamborghini Espada Single Distributor Electronic Modification By Nash Bapasola This electronic modification uses two Crane XR700-0231 optical units arranged within the distributor with a six(6) slot shutter wheel so that each trigger block fires six times feeding into a control unit and a coil. The installation is fairly straightforward; however, particular attention should be paid to the following: The first trigger block should be adjusted so that a spark is generated whenever the center of the rotor tip lines up with the red groove in the distributor body. This ensures the correct phasing of the rotor relative to the contact block in the distributor cap for cylinder #1. This also happens to be the correct way to set up the first point set if you are still going to use points and is contrary to the instructions in the Crane manual. The Distributor Showing the Two Optical Triggers in Place Under the Plate The second trigger should now be adjusted so that the spark is generated exactly 30 degrees after the first spark.

Lamborghini Espada Single Distributor Electronic Modification By Nash Bapasola This electronic modification uses two Crane XR700-0231 optical units arranged within the distributor with a six(6) slot shutter wheel so that each trigger block fires six times feeding into a control unit and a coil. The installation is fairly straightforward; however, particular attention should be paid to the following:

• The first trigger block should be adjusted so that a spark is generated whenever the center of the rotor tip lines up with the red groove in the distributor body. This ensures the correct phasing of the rotor relative to the contact block in the distributor cap for cylinder #1. This also happens to be the correct way to set up the first point set if you are still going to use points and is contrary to the instructions in the Crane manual.

after the first spark.

The picture on the previous page shows the two optical triggers within the distributor with the placement of the two units bottom to bottom (just like the original Bosch units were mounted). The picture below shows the distributor mounted on my homemade stand that facilitated the final setup. Notice the degree wheel mounted under the distributor to permit the precise setup. I downloaded the degree wheel from www.machinerycleanery.com in the size that I needed, stuck on stiff cardboard with a center hole cut for the distributor shaft bottom. Worked great. I also utilized this setup to adjust the distributor advance by shining a timing light at the wheel and driving the distributor thru a variable speed drill up to 5500rpm hooking up both units and two coils.

While I was at it, I replaced the top and bottom distributor bearings-top bearing # 63000-2RS, bottom bearing # 62202-2RS. Besides not having to fuss with any point adjustments in the future this setup eliminates timing variation from cylinder to cylinder caused by variations within points, lobe wear and wear between the rotor and the center shaft. The photo on the last page shows the location of the Crane controller box in the engine compartment.
