i Y 111 i Fig 8 58 Checking Breoker Arm Spring Tension 5 Place contact point assembly in position ovei pivot post and install hold down screws 6 Insert wire leads into position and tighten primary terminal screw securely 7 Set point opening and align points as described under Setting and Alignment of Points Point opening should be 019 8 Check and set ignition timing with a timing light See Tune up in Section 7 DISTRIBUTOR CONDENSER Performance The following four factors affect condenser performance and each factor must be considered in making any condenser test Breakdown a failure of the insulating material a direct short between the metallic elements of the condenser This prevents any condenser action Low Insulation Resistance Leakage prevents condenser from holding a charge All condensers are subject to leakage which up to a certain limit is not objectionable High Series Resistance excessive resistance in the condenser circuit due to broken strands in condenser lead or to defective connections This will cause burned points and ignition failure upon initial start and at high speeds Capacity determined by the area of the metallic elements and the insulating and impregnating materials For a complete check of the condenser use a tester which will check for the above conditions Follow the instructions given by the manufacturer of the test equipment Condenser capacity should be 18 23 microfarad DISTRIBUTOR Removal 1 Disconnect the distributor primary wire from coil 2 Remove the distributor cap by releasing two spring clamps 3 Remove the vacuum line from the distributor NOTE Mark position of rotor arm so that distributor may be reinstalled in the same position 4 Remove distributor clamp screw and hold down clamp then remove distributor 5 If necessary to remove secondary leads from distributor cap mark position on cap tower for lead to No 1 cylinder This will aid in reinstallation of leads in cap Disassembly Refer to Figure 8 59 With the distributor removed from the vehicle it is advisable to place it in a distributor testing machine or synchroscope CAUTION When mounting the distributoi in any distributor testing machine or synchroscope extreme care must 6e taken not to score or otherwise damage the lower distributor shaft with the testing machine drive mechanism A protective adapter available from the manufacturers of such testing machines for use with the Corvair distributor must be used over the lower 1 la of the distributor shaft Test the distributor for variation of spark correct centrifugal and vacuum advance and condition of contacts This test will give valuable information on distributor condition and indicate parts replacement which may be necessary Check area on breaker plate just beneath breaker points A smudgy line indicates that oil or crankcase vapors have been present between points 1 Remove the rotor 2 Remove both weight springs and both advance weights 3 Drive gear pin and thrust washer pin from shaft with a flat drift punch 4 Slide gear and thrust washers off the shaft 5 Remove any burrs around pin holes in shaft with flat file These burrs will damage housing bushing it not removed before removal of shaft 6 Pull shaft and cam weight base assembly from housing 7 Remove circuit breaker cam and weight base assembly from shaft 8 Remove condenser hold down screw condenser and bracket from breaker plate after removing condenser and primary leads from primary terminal
