A piston stopper is used to stop the piston so that the crankshaft can no longer rotate.
This makes it possible to unscrew the crankshaft nut at the variator without it twisting.
A piston stopper is rotated into the spark plug hole, the piston comes against the piston stop when you hit the
variator is running. Because the piston cannot go further up in the cylinder, the crankshaft blocks.
A piston stopper can cause damage to the piston if used incorrectly.
A piston stop is also only suitable for 2-stroke engines. With 4-stroke engines, the piston stop can
the valves hit with major damage as a result.
In addition, the piston stop is obliquely on the piston at a 4-stroke so that a lot too much pressure is placed on a small area.
Zandri recommends using a variator-lock key if it is available for your type of scooter.
If you want to replace the variator rollers, the variator must be disassembled. Do you want to replace the coupling segments
then the clutch must be disassembled. At Zandri you will find this tool. If you are in doubt and do not know exactly which blocking tool is suitable for your moped or scooter, please contact customer service. Speak to us on the chat or use our contact form.
