Lock-In-Tool has the right idea when it comes to dealing with spiral and wire wrist-pin locks, which are notorious for being difficult during installation and removal. In fact, it’s the type of tool that you won’t know you’ll love unless you use it. Your fingers, particularly your thumbs, will be especially grateful. In addition to preventing injuries, it eases the workload and helps avoid piston damage and bent locks.
The Lock-In-Tool spiral-loc installation and removal tools are available in hardened steel tool available for professional engine builders, or a lightweight plastic tool available for the do-it-yourself engine builder. They’re available in two sizes, .927-inch and .990-inch. The tool handle is engineered so that each tool head is interchangeable.
