NOTE: Make sure the mounting surfaces of the crankshaft nose, vibration damper, and pulley are clean, dry, and free of burrs.

Install two guide pins into the end of the crankshaft.

Install the pulley and vibration damper.

Lubricate the threads of the capscrews and washer with a film of SAE 15W-40 oil.

Install four of the six mounting capscrews.

Remove the two guide studs, and install the remaining two capscrews.

Install the washers and capscrews.

Keep the crankshaft from rotating and tighten the capscrews to the following torque values in the sequence illustrated.

Install the dial indicator onto the gear cover, as illustrated, to measure the damper eccentricity.

Rotate the crankshaft and record the indicator movement.

Replace the vibration damper if the eccentricity exceeds 0.10 mm [0.004 in] per 25.4 mm [1.0 in] of the damper diameter.

Install the dial indicator, as illustrated, to measure wobble.

Push the crankshaft to the front or rear.

Rotate the crankshaft 360 degrees, maintaining the position of the crankshaft (either toward the front or the rear) in relation to the block.

Record the total indicator motion.

Replace the damper if the wobble exceeds 0.18 mm [0.007 in] per 25.4 mm [1.0 in] of radius.
