REMOVAL & INSTALLATION
See Figures 1, 2 and 3
Point alignment is preset at the factory and requires no adjustment. Point sets using the push-in type wiring terminal should be used on those distributors equipped with an R.F.I. (radio frequency interference) shield (1970-74). Points using a lockscrew type terminal may short out due to the shield contacting the screw.
The optional magnetic pulse distributor and the HEI (High Energy Ignition) system used on some 1974 and all 1975-79 models requires no maintenance other than checking the condition of the cap and wires. There are no points to wear out or adjust.
- Remove the radio interference shield from around the distributor. Unlatch and remove the distributor cap.
- Remove the rotor.
- If so equipped, remove the two-piece R.F.I. shield.
- Loosen the two mounting screws and slide the contact point set from the breaker plate.
- Remove the two wires which are connected to the point set.
- Loosen the condenser bracket screw and slide the condenser from the bracket.
- Install the new point set and condenser and then tighten the mounting screws.
- Install the wires to the terminal so that they will not interfere with the cap, weight base, or breaker advance plate. Install the half of the R.F.I. shield which covers the points first.
- Have an assistant "tap" the ignition key to turn the engine until the rubbing block of the point set is centered on one of the distributor cam lobes. Turn the ignition key OFF.
- Using a 1 / 8 in. allen wrench, make an initial point setting of 0.019 in.
- The cam lubricator (if so equipped) must be replaced after 12 months or 12,000 miles. The end of the lubricator should be adjusted to just touch the cam lobes. Additional grease should not be applied to the lubricator.
- Install the rotor. The two lugs on the bottom of the rotor are shaped differently, so that it can only be installed one way. Tighten the screws. Start the engine and check the point dwell and the ignition timing.
