INSPECTION

1. Check cylinder block for following conditions and repair or replace cylinder block as needed.

(1) A. Leakage damage

B. Cracks

C. Scoring of cylinders

2. Check distortion of cylinder head mating surface (block deck) in six directions shown in figure.

Distortion : 0.006i (0.15mm) maximum

3. Repair block deck by surface grinding blocl, or in extreme cases replace cylinder block.

Maximum resurface amount : 0.008in (0.20mm)

4. If deck is at or below this specification, replace cylinder block.

Before surfacing cylinder block, check deck height from center line of crankshaft to deck surface.

5. Measure cylinder bore with a dial gauge at X and Y vectors shown in figure.

Cylinder bore size :
Standard : 3.1892~3.1897in (81.006~81.019mm)
Bore + 0.010 in (0.25mm) : 3.1990~3.1996in (81.256~81.269mm)
Bore + 0.020in (0.50mm) : 3.2089~3.2094in (81.506~81.519mm)

6. Take cylinder measurements at top center an bottom of cylinder to check for cylinder diameter, taper and

out of round.

Taper : 0.0007in (0.019mm) Maximum
Out-of-round : 0.0007in (0.019mm) Maximum

Boring cylinder should be based on maximum oversized piston that can be installed without exceeding
