Continue to tighten screwsuntil flywheel loosens, Fig. 30. NOTE: Use flywheel nutto protect crankshaft threads.Fig. 30 - Removing FlywheelSet point gap at .020" (0.5 mm). Position flywheel oncrankshaft taper. Slip key in place. Install flywheel nutfinger tight. Rotate flywheel and crankshaft clockwiseuntil breaker points are just opening. Use a timing light.When points just start to open, arrow on flywheel shouldline up with arrow on armature bracket, Fig. 31.If arrows do not match, slip off flywheel without disturbingcrankshaft position.
