Removing the cylinder - piston assy.

- Drain the coolant out of the system

- Remove the cylinder head

- Remove the cooling circuit rubber pipe between

the cylinder and the water pump

- Move the cylinder slowly upwards

- Remove the base gasket

- Put a piece of old cloth in the cylinder housing

hole on the crankcase so that no object can fall in

- Remove the seeger ring retaining the pin

- The pin

- The Piston

- The piston sealing circlips (piston rings)

- When pulling the pin, be careful to fasten the

connecting rod properly to avoid distortions

- Check and clean the components

- Clean the piston crown by carefully removing any

possible carbon deposits

- Visually check the piston sealing circlips. Re-

place the piston if it is damaged or distorted
