Resorting to a flathead screwdriver or needle nose pliers to pry a circlip into place isn't just difficult—it risks bending the wire clip. A damaged or weakened circlip can jump out of its groove while the engine is running, leading to catastrophic engine failure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: 'Aptos',sans-serif;\"\u003eThis purpose-built, two-piece Piston Circlip Installer Tool is the ultimate solution.
