Distributor: Service and Repair

Dual Distributors W/Single Mount
1. Set cylinder No. 1 on TDC, compression stroke.
2. Remove ignition cables from holders.
3. Remove distributor caps. Ensure rotor tips are aligned with marks on upper distributor housings.
4. Remove distributor hold-down bolt, then the distributor.
5. Reverse procedure to install. After installing distributor make sure that rotor tips are aligned with marks on distributor housing.
6. It is not necessary to check ignition timing after distributor installation as the distributor's only function is to distribute secondary voltage. Ignition timing, dwell and advance functions are electronically controlled.

Dual Distributors W/Remote Mounts
These engines do not use a conventional distributor. Instead, the distributor rotors are driven directly from the camshaft. The only purpose the distributor caps and rotors serve is to deliver secondary voltage. Ignition timing, dwell and advance functions are controlled by the engine ignition system electronics.
