Gudgeon pins - inspection

NOTE: Gudgeon pins are only supplied as
an assembly with replacement pistons.

1. Check gudgeon pins for signs of wear and

overheating.

2. Check clearance of gudgeon pin in piston.

Gudgeon pin to piston clearance = 0.006 to
0.015 mm (0.0002 to 0.0006 in).

3. Check overall dimensions of gudgeon pin.

Overall length = 60.00 to 60.50 mm (2.35 to 2.4
in).
Diameter - measured at each end and centre
of pin = 23.995 to 24.00 mm (0.94 to 0.95 in).

Cylinder liner bore - inspection

1. Measure cylinder liner bore wear and ovality in

two axis 40 to 50 mm (1.5 to 1.9 in) from top of
bore.
Cylinder liner bore:
Grade ’A’ piston fitted = 94.00 to 94.015 mm
(3.700 to 3.701 in)
Grade ’B’ piston fitted = 94.016 to 94.030 mm
(3.7014 to 3.702 in)
Maximum ovality = 0.013 mm (0.0005 in)
Cylinder liners having grade ’A’ pistons fitted
may be honed to accept grade ’B’ pistons
provided specified wear and ovality limits are
maintained.

CAUTION: The temperature of piston and
cylinder block must be the same to ensure
accurate measurement. DO NOT attempt

to de-glaze cylinder bores.

2. Check alignment of connecting rods.
