Procedure to Measure Wobble
1. Install a dial indicator, contact point and other parts as needed to hold the dial indicator stationary. The contact point must be perpendicular (at 90° angle) to the face of the outer ring of the damper and must make contact approximately at the center of the outer ring.2. Push on the end of the crankshaft so the end play (free movement on the centerline) is removed. Keep the crankshaft pushed back until the measurements are done.3. Adjust the dial indicator to zero.4. Turn the crankshaft 360° and watch the dial indicator. A total indicator reading of .080" (2.03 mm) or less is acceptable.
