(5) Inspect coil for visible radial cracks. Replace coil if cracks evident. Inspect coil for primary and
secondary circuit resistance and continuity, as follows: primary coil - .50 to 1.2 ohms;
secondary coil - 13,000 to 20,500 ohms. Replace, if required.
(6) Inspect primary contact points for signs of pitting and discoloration. If points are not discolored
and have a white, frosty surface around the edges, points are functioning properly and can be
reused. If points are blue (indicating excessive arcing) or pitted, they should be discarded.
Replace primary contact point assembly, condenser and cam.
(7) Clean and inspect condenser.
(a) If the external surfaces of the condenser are dirty, clean with light soapy water. Rinse
thoroughly with clear water and pat dry before reinstalling into the magneto housing.
(b) Using a magnifying lens, examine the glass bead end seals of the capacitor for broken
glass or for glass separation from the retaining steel rings. Replace, if required.
(c) Inspect the condenser for signs of corrosion. Replace, if required.
(d) Inspect the condenser P-lead stud for twisting or "pulled" condition. Replace, if required.
(e) Test the electrical properties of the condenser using appropriate calibrated test
equipment. Test for capacitance value with condenser charged to 400 volts DC. Service
limit: .35 microfarad + 10 percent. Test for resistance, measured between condenser lead
wire and condenser shell. Resistance should be greater than 10 megaohms.
NOTE: No field repairs of any type to the condenser are approved.
(f) Install condenser per paragraph E (12), below.
(8) Clean and Inspect Distributor Block
CAUTION: DO NOT PUT CLEANER IN EITHER BRONZE OILITE BUSHING. THESE
BUSHINGS ARE IMPREGNATED AT THE FACTORY AND CLEANER WILL
DRAW THE LUBRICANT OUT OF THE BUSHING.
(a) Disassemble and clean the distributor block bearing bar. Use standard non-filming non-
conductive cleaner. Clean distributor gear with soapy water and rinse with clean water.
(b) Clean all surfaces free of dirt, oil, carbon dust and other contaminants using a cotton
swab or "Q-Tip".
(c) Inspect the distributor block for cracks or other physical damage. Replace, as required.
(d) Inspect the brass electrode posts for signs of physical wear. Replace block assembly, as
required, but note that during normal operation, the post will experience an electrical-
metal transfer with the distributor gear electrode.
(e) Inspect oilite bushing for gumming oil. The bushing should be free of contamination and
the gear should turn freely in the distributor block with no appreciable drag. If the bushing
is gummed, wipe the bushing with MEK and lubricate with one drop of Exxon Teresstic
100 or Slick P/N M-3306. No other oils should be placed in these bushings.
(f) Ensure the distributor block surfaces are free of all oil and carbon dust prior to
reassembly.
(g) Inspect distributor gear teeth for wear and general integrity. Replace block assembly as
required.
(h) Inspect the electrode finger for looseness. The electrode should be held securely to the
shaft when tested with light finger pressure. If loose, replace block and gear.
(i) Clean the end of the electrode to remove electrical deposits.
(j) Inspect bearing bar for cracks or other physical damage. Replace as required.
(k) Ensure the bearing bar is free of all and carbon dust prior to reassembly.
