Piston stopper M14/70mm with PVC head Ttoolz

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 stop is rotated into the spark plug hole, the piston comes against the piston stop when you turn the variator. 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.

This piston stopper from the brand Ttoolz has a threaded diameter of 14mm and is 70mm long. The piston stopper is equipped with a PVC head to reduce the risk of damage to the piston.
