Refitting the piston rings
- Fit the oil scraper ring starting from the spring,
taking care that the spring ends do not superim-

- Fit the 2nd sealing ring with the identifying letter
«
T
» facing towards the piston crown.
- Fit the 1st sealing ring with the reference letter
«

- Lubricate the components with engine oil.
N.B.

- Alternately insert the three sealing rings into the
cylinder, in the area where it retains its original di-

rings using a thickness gauge.
- If any measurements are greater than specified,
replace the piston rings.
