Remove piston rings (8- 9 - 10).
To avoid breakage of the piston rings during operation and during assembly / dismantling of the fire and compression rings, it is vital to not exceed the spacing distance X.Fire ring (8): X = 37.6 mmCompression ring (9): X = 38 mmOil scraper ring (10): X = 34.1 mm
Pistons

Liners
The O-rings for cylinder liners are made from fluoride rubber. When the fluoride rubber is subjected to elevated temperatures (more than 300°C), hydrofluoric acid may be formed. Hydrofluoric acid is highly corrosive!
* Contact with the skin may cause ulcers.

*Splashing into the eyes may cause serious burns.
*Breathing in the vapours may cause lesions in the respiratory tracts.
Pay utmost attention when working on engines that may have been subjected to elevated temperatures, e.g. overheating caused by seizing or fire.Under no circumstances should cylinder liner O-rings be burnt after disassembly or incinerated under non-controlled conditions.
*Always wear chloroprene gloves (gloves for handling chemical products) and safety goggles for protection.
*Handle removed O-rings as if they were an acid.
*Never use compressed air to clean off residue. Even the ashes may still be extremely corrosive.
*Put all the remains in a plastic box TO WHICH a label with a warning text is to be affixed.
*Before taking off the gloves, wash them in running water.
