deposits from the pistons. Take care to avoid scratching
the pistons.
Use an appropriate solvent to clean any remaining
carbon from the pistons. Blow-dry the pistons with
compressed air.
Inspect the pistons for cracks, grooves and burnt spots.
Check the wrist pins for pitting and scoring.
Inspect the wrist pin bushing in the connecting rods for
wear or damage. Check that wrist pin-to-bushing
clearance is within specification (see Specifications).
Replace worn parts as required.
Check that the wrist pin-to-piston clearance is within
specification (see Specifications). Replace worn parts as
required.

specifications (see Specifications). Use the piston top
surface to square each ring in the cylinder when
measuring ring gaps. Replace the rings if the ring gap is
not within specification.
