PISTON—GUDGEON PIN ASSEMBLY
1. Piston — 2. Trapezoidal grommet — 3. Washer — 4. Oil
scraper ring — 5. Gudgeon pin — 6. Split rings — 7. Half
baerings — 8. Connecting rod — 9. Bush
- Check pistons for any signs of seizure, cracks or excessive
wear; if there are, replace them.
- Use pincers 99360183 (1) to remove the rings (2) from
the piston.
- Remove the piston (1) from the rod (3) by removing the
ring (2) and extracting the gudgeon pin (4).
- Measure through the micrometer (1) the piston diameter
(2) to determine the assembly play. The diameter shall be
measured at 21 mm from the piston skirt.
- The clearance between the piston (1) and cylinder liner
can be checked using a feeler (2) as shown in the above
figure.
- Measure the diameter of the gudgeon pin (1) using a
micrometer (2).
