27. CHECK CYLINDER BLOCK FOR WARPAGE
(a) Using a precision straight edge and feeler gauge,
measure the warpage of the contact surface of the
cylinder head gasket.
Maximum warpage:
0.05 mm (0.0020 in.)
If the warpage is greater than the maximum, replace
the cylinder block.
28. INSPECT CYLINDER BORE
(a) Using a cylinder gauge, measure the cylinder bore
diameter at positions A and B in the thrust and axial
directions.
Standard diameter:
94.000 to 94.012 mm (3.7008 to 3.7013 in.)
Maximum diameter:
94.132mm (3.7060 in.)
If the average diameter of the 4 positions is greater
than the maximum, replace the cylinder block.
29. INSPECT WITH PISTON SUB-ASSEMBLY
(a) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 27.7 mm
(1.091 in.) from the piston head.
Piston diameter:
93.910 to 93.940 mm (3.6972 to 3.6984 in.)
If the result is not as specified, replace the with
piston sub-assembly.

30. INSPECT PISTON OIL CLEARANCE
(a) Subtract the piston diameter measurement from the
cylinder bore diameter measurement.
Standard oil clearance:
0.060 to 0.102 mm (0.0031 to 0.0040 in.)
Maximum oil clearance:
0.13 mm (0.0051 in.)
If the oil clearance is greater than the maximum,
replace all the 6 pistons. If necessary, replace the
cylinder block.
31. INSPECT CONNECTING ROD SUB-ASSEMBLY
(a) Using a rod aligner and feeler gauge, check the
connecting rod alignment.
(1) Check for misalignment.
Maximum misalignment:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If misalignment is greater than the maximum,
replace the connecting rod assembly.
(2) Check the twist.
Maximum twist:
0.15 mm (0.0059 in.) per 100 mm (3.94 in.)
If the twist is greater than the maximum,
replace the connecting rod assembly.
32. INSPECT PISTON PIN OIL CLEARANCE
(a) Using a caliper gauge, measure the internal
diameter of the piston pin hole.
Piston pin hole internal diameter:
22.001 to 22.010 mm (0.8662 to 0.8665 in.)
Piston pin hole inside diameter
(b) Using a micrometer, measure the piston pin
diameter.
Piston pin diameter:
21.997 to 22.006 mm (0.8660 to 0.8664 in.)

(c) Using a caliper gauge, measure the internal
diameter of the connecting rod bushing.
Bushing internal diameter:
22.005 to 22.014 mm (0.8663 to 0.8667 in.)
Bushing internal diameter
(d) Subtract the piston pin diameter measurement from
the piton pin hole diameter measurement.
Standard oil clearance:
0.001 to 0.007 mm (0.00004 to 0.00028 in.)
Maximum oil clearance:
0.040 mm (0.0016 in.)
(e) If the oil clearance is greater than the maximum,
replace the bushing. If necessary, replace the piston
and piston pin together.
(f)
Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance:
0.005 to 0.011 mm (0.0002 to 0.0004 in.)
Maximum oil clearance:
0.050 mm (0.0020 in.)
(g) If the oil clearance is greater than the maximum,
replace the bushing. If necessary, replace the
connecting rod and piston pin together.
33. INSPECT RING GROOVE CLEARANCE
(a) Using a feeler gauge, measure the clearance
between a new piston ring and the wall of the ring
groove.
