INSTALLATION - Continued
Dial indicator tip must not enter capscrew holes or gage will be damaged.
Extension bar for dial indicator must be rigid for an accurate reading.
Position dial indicator at 12 o'clock position. Adjust dial until needle points to zero.
Slowly rotate crankshaft. Record readings obtained at 3 o'clock, 6 o'clock, and 9 o'clock positions.
Continue to rotate crankshaft back to 12 o'clock position. Check dial indicator to make sure needle points to
zero. Determine Total Indicator Reading (TIR).
12 o'clock = 0.000 inch (0.00 mm)
3 o'clock = +0.003 inch (0.08 mm)
6 o'clock = -0.002 inch (0.05 mm)
9 o'clock = +0.003 inch (0.08 mm)
Equals TIR = 0.005 inch (0.13 mm)
