Refer to Illustration 61. 2. Set the pointer of the 21825617 dial gauge to 0 mm (0 inch). 2. Set the pointer of the dial indicator to 0 mm (0 inch). 3. Turn the flywheel. Read the dial indicator for every 90 degrees. 3. Check the concentricity at intervals of 90 degrees around the flywheel housing. 4. Calculate the difference between the lowest measurement and the highest measurement of the four locations. This difference must not be greater than 0.30 mm (0.012 inch). 4.
Calculate the difference between the lowest measurement and the highest measurement. This difference must not be greater than the limit that is given in Table 7. Note: Any necessary adjustment must be made on the flywheel housing. Then, recheck the concentricity. i02270535 Flywheel Housing - Inspect Alignment of the Flywheel Housing Note: This check must be made with the flywheel and the starter removed and the bolts for the flywheel housing tightened to the correct torque. Concentricity of the Flywheel Housing Table 6 Note: This check must be made with the flywheel and the starter removed and the bolts for the flywheel housing tightened lightly.
