drawn to specified torque.

Check crankshaft end play as follows:

a.

Mount dial indicator with magnetic base (Figure 10, Item 24) on rear of cylinder block with indicator

point resting on rear face of crankshaft gear (Figure 10, Item 16).

b.

Using large screwdriver between main bearing cap and crankshaft counterweight, push crankshaft

toward dial indicator with magnetic base. With constant pressure on screwdriver, set dial indicator with

magnetic base to zero.

NOTE

If correct crankshaft endplay cannot be obtained with standard size thrust

washers, use 0.005 or 0.010 in. oversize washers.

Insufficient end play can result from a misaligned rear main bearing or a burr

or dirt on inner face of one or more thrust washers.

0.004–0.016 in. (0.10–0.41 mm) with new parts and maximum of 0.018 in. (0.46 mm) with used parts.
