Cleaning, inspection
After dismantling, clean the individual components:
1. Scrape carbon deposits from the top of the piston.
2. Scrape carbon deposits from the cylinder’s combustion chamber.
3. Scrape carbon deposits from the cylinder’s exhaust port.
Dismantle the piston. Press out the gudgeon pin from the
piston using the punch 505 38 17-05.
If the pin is too tight, carefully warm the
piston.
4. Wash all the components.
5. Inspect the different components for damage and wear.
Check the piston and cylinder for seizure damage and wear.
Also see the “Analysis and actions” section.
Check the gudgeon pin.
– If it has blued, it must be replaced.
– If the piston moves too easily both the piston and the gudgeon pin must be replaced.
Check the needle bearing. If it is discoloured or damaged, it must be replaced.
Check the circlips. If they exhibit cracks or are discoloured (caused by overheating),
they must be replaced.
NOTE!
Scrape carefully with not too sharp a tool so as not to damage the soft
aluminium parts.
