Glide Manual Circuit Breakers

Remove spark plugs to permit engine to turn easily; remove screw plug from timing inspection hole in left side of crankcase. Telescope front push rod cover so that opening and closing of valve can be observed. Turn engine in direction in which it runs until front piston is on compression stroke (just after front intake valve closes) and continue turning engine very slowly (less than 1/2 revolution) until advance timing mark on flywheel is aligned in the inspection hole as shown in Fig. 5F-3.

Assemble circuit breaker as follows (See Fig. 5F-2):

Position circuit breaker base assembly (10 or 10A) on shaft and stem assembly (22 or 22A), wrapping wire (12 or 12A) clockwise around shaft. Install base retainer (20) over wire, retainer ends facing down and toward front cylinder. Engage cover retainer (1) with holes in base and register retainer ends in locating notches of base retainer (20).

Make sure timing mark (8, Fig. 5F-1 or 5F-1B) on circuit breaker base aligns with end of adjusting stud plate (10).

Install a new circuit breaker gasket (23 or 23A, Fig. 5F-2) using gasket sealer. Turn circuit breaker shaft counterclockwise approximately 60 degrees from position where mark on cam lobe lines up with breaker lever fiber.

Temporally insert circuit breaker assembly into gear case, with adjusting stud pointing toward the front of motorcycle and screw holes of stem housing lined up with mounting holes in crankcase. Move circuit breaker base (10 or 10A) to fully advanced position (counterclockwise) and observe how close timing mark on cam lobe lines up with breaker lever fiber.
