Breaker contacts — preliminary gap adjustment (Peugeot 305)

1. To accurately regulate the gap between the contacts of the breaker, a device for measuring the angle of the closed state of the contacts is required (see next section). Since not everyone has it, below we provide the procedure for adjustment using thickness gauge feeler gauges. This preliminary adjustment will allow you to get to the nearest workshop where the clearance will be adjusted precisely. Even if you have a device for measuring the angle of the contacts, you must first adjust the gap using feeler gauges before using it.

2. Release the distributor cap clamps and remove it. Wipe the cover with a dry, clean cloth and inspect the electrodes for excessive burning. Check to see if there are any cracks on the lid. If the electrodes are burnt or cracked, the cover must be replaced.

3. Inspect the "coal" in the center of the lid for damage. Press it a few times and check that it can move freely.

4. Carefully remove the runner from the cam and wipe it with a dry, clean cloth. A burnt or cracked runner must be replaced.


5. Using a small screwdriver, carefully pry open the breaker contacts and inspect them carefully. If they are worn, burnt or dirty, they must be removed for cleaning or replacement (see section 4).



6. If the contacts are in good condition, turn the crankshaft in the direction of its rotation using a wrench placed on the crankshaft pulley bolt so that the back side of the movable contact rests on the top point of one of the cam contours.

7. Using feeler gauges of the required thickness (see Specifications) check the gap between the contacts. The probe should pass between the contacts with a slight tension, without spreading them apart. Be careful not to get any oil on the contacts during testing.

8. If adjustment is necessary, proceed as follows (depending on the brand of distributor).

9. Ducellier. Using a 7 mm open-end or socket wrench, turn the adjusting nut on the side of the distributor to obtain the desired clearance (see photo).



10. Paris-Rhone. Insert a 3 mm Allen key into the hole in the plastic plug on the side of the distributor until it fits into the recess on the fixed contact, and turn the key to obtain the desired clearance.

11. When finished, turn the crankshaft so that the back side of the sliding contact is at the top point of the next cam contour, and check the clearance again. Any changes in the gap size indicate that the distributor requires repair. If there are significant changes, the roller must be replaced.



12. Install the rotor and distributor cap in place. Secure the lid with clamps.
