8T-5096 Dial Indicator Group 1 Face Runout (Axial Eccentricity) of the Flywheel housing
Illustration 1 g00285931
Face runout check
Position the magnetic base of the dial indicator on the crankshaft flange. Position the contact of the dial indicator on the face of the flywheel housing.
Force the crankshaft to the rear in order to remove the clearance for the main bearing.

Locations for measuring the face runout of the flywheel housing
(A) Bottom
(B) Right side
(C) Top
(D) Left side
Set the dial indicator to 0.0 mm (0.00 inch) at location (A). Turn the crankshaft in order to measure the face runout at locations (B), (C), and (D).
Maximum face runout Calculate the difference between the lowest measurement and the highest measurement of the four locations. This difference must not be greater than the limit that is given in the following table. This difference is the maximum permissible face runout of the flywheel housing.

Fasten the magnetic base of the dial indicator to the crankshaft flange. Adjust the contact of the dial indicator in order to touch the bore of the flywheel housing at location (1). Set the pointer of the dial indicator to 0.0 mm (0.00 inch).
Push the crankshaft to the rear in order to remove the main bearing clearance before the measurement is taken at each location.
Turn the crankshaft. Record the dial indicator reading at locations (2), (3), and (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). This dimension is the maximum permissible distance for the bore runout of the flywheel housing.
