tapers and nut over-tightened. Disassemble, clean
and reassemble.
b. 
New flywheel washers installed and not fully seated.
Disassemble, inspect, replace deepest seating fly-
wheel or crank pin. As last resort, grind down width
of forked rod.

taken apart several times. Replace deepest seating
wheel.

Cracked flywheel at tapered hole. Replace flywheel.
19. After rod side play is checked and adjusted, check that
crank pin nut is tightened to specified torque, again
check wheel trueness on truing device. Correct any
runout as above.
