What is the usage method of piston ring pliers?

[LaMadelyn]

The usage method of piston ring pliers is as follows: 1. When using piston ring pliers, clamp the ring opening with the pliers' ring clamp, gently hold the handle and apply even force, slowly contracting the handle to gradually open the piston ring with the ring clamp, then install or remove the piston ring from the ring groove; 2. When installing or removing piston rings with the pliers, the force must be applied evenly to avoid breaking the piston ring due to excessive force and to prevent hand injuries. Piston rings are parts that wear severely in the piston assembly and are also one of the vulnerable parts of diesel engines. The wear of piston rings mainly occurs on the outer cylindrical surface and the upper and lower planes. Sometimes, piston rings may also experience sticking or breaking. Piston ring pliers are used for installing and removing engine piston rings to avoid uneven force application that could lead to breakage.
