Description

TIP:Please always mount the piston rings carefully. Piston rings made of cast material have only limited elasticity and break relatively quickly.
Some pistons have trapezoidally profiled piston rings (so-called keystone rings), these only fit in one installation position. If the ring is not free, please loosen it carefully and reinstall it upside down.
