Cylinder bores - Inspection
1. Check cylinder bores for scoring.
2. Measure cylinder bore wear and ovality at a
point 70 mm (2.75 in) from top of each cylinder
bore:
Cylinder bore diameter = 84.460 to 84.442 mm
(3.325 to 3.324 in)
CAUTION: Measurement must be taken
from side to side and front to rear of bore:
CAUTION: Cylinder bore diameter and
ovality must be within limits given above,
no reboring, honing or glaze busting of
cylinder bores is permissible; cylinder block must
be replaced if bores are worn or excessively
scored.
Pistons and connecting rods - Inspection
1. Check each piston for cracks, burning and
damage.
2. Check connecting rods for alignment.
CAUTION: Do not attempt to straighten
misaligned connecting rods.
3. Ensure small-end oil feed holes in connecting
rods are clear.
4. Measure and record diameter of each piston at
right angles to gudgeon pin axis and 46 mm
(1.81 in) from bottom of skirt:
Piston diameter = 84.262 mm
±
0.009 mm
(3.317 in
±
0.0003 in)
CAUTION: Measurement point must be on
the graphited area of the piston.
