• piston:
- There must not be any signs of seizure or deep cracks.
- Check the wear by measuring the piston at 21,7mm from the bottom keeping
the measuring instrument at a right angles to the axis pin.
Height limits:
SELECTION A: 69.89mm
SELECTION B: 69.90mm
SELECTION C: 69.91mm
• The pin must not be blue because that indicates a high working temperature and
the external diameter must not be less than 17.990mm.
• Measure the slack between the piston ring and its seat: slack height limit 0.1mm.
• Piston ring: insert a piston ring in the cylinder one by one, by using the piston, so
it is a square, measure the gap that is created between the two ends of piston ring
