BASIC BLOCKTM 5-3805-263-14&P-2TESTING AND ADJUSTING1. Fasten a dial indicator to the crankshaft flangeso the anvil of the indicator will touch the face ofthe flywheel housing.Bore Runout (radial eccentricity)of the Flywheel Housing2. Put a force on the crankshaft toward the rearbefore reading the indicator at each point.3. With dial indicator set at 0.0 mm (.000 in.) atlocation (A), turn the crankshaft and read theindicator at locations’(B), (C) and (D).4. The difference between lower and higher mea-surements taken at all four points must not bemore than 0.30 mm (.012 in.), which is the maxi-mum permissible face run out (axial eccentri-city) of the flywheel housing.1. With the dial indicator in position at (C), adjustthe dial indicator to “0” (zero). Push the crank-shaft up against the top bearing. Write the mea-surement for bearing clearance on line 1 in col-umn (C).NOTE: Write the dial indicator measurementswith their positive (+) and negative (-) nota-tion (signs). This notation is necessary formaking the calculations in the chart correctly.2. Divide the measurement from Step 1 by 2. Writethis number on line 1 in columns (B) & (D).1-72
