NOTE

Main bearing caps are numbered to correspond with their respective positions in

cylinder block. No. 1 bearing cap is located at front of block and stamped on

bottom of front oil pan rail.

Install main bearing bolts, bearing caps, stabilizers, and hardened washers

(WP 0097).

7.

Using cylinder bore gage, measure diameters of main bearing bores (Figure 6, Item 36) with bearing caps in

original position. Diameter of main bearing bore is 3.751–3.752 in. (95.28–95.30 mm). If bores do not meet

these limits, replace cylinder block.

8.

Measure diameter of camshaft bearing bores. End bearing bores must be 2.3750–2.3760 in.

(60.325–60.350 mm) for standard bearings and 2.3850–2.3860 in. (60.579–60.044 mm) for oversized

bearings. Intermediate bearing bores must be 2.3650–2.3660 in. (60.071–60.096 mm) for standard bearings

and 2.3750–2.3760 in. (60.325–60.350 mm) for oversized bearings.

9.

Check remaining cylinder block surfaces and threaded holes for damage. Check all mating surfaces or

mounting pads for flatness, nicks, and burrs. Clean up damaged threads in tapped holes with a tap or install

helical thread inserts if necessary.

10.

Check for cracking in area between center water transfer holes and cylinder head to block bolt holes

(cam and exhaust sides). If cracks are found, replace cylinder block.
