Review: Cut my hand - Work great for my 212 rebuild. If you buy it go easy. I cut the heck outta my hand with this thing, it’s sharp. Review: Worked perfectly - I bought this for my first time replacing piston rings in a vehicle. The tightening mechanism is stout, and the thumb tab loosens the band with just a push (make sure your hands are around the band when doing this, otherwise the spring tension of the band makes it quickly snap open too loose). At first, I thought the allen wrench supplied to tighten the band could have been a better design, as it makes it too hard to tighten the band after a certain point. After installing my four 3.150" pistons, I realized that this prevented me from making the band TOO tight. As it was, the band was tightened the perfect amount, compressing the rings just enough while still allowing the oiled piston to be easily tapped into the bore. No problems with the band itself being tapped into the bore along with the piston. Judging from the construction quality of this tool, it will last me a lifetime even if I start replacing piston rings on a regular basis (which hopefully, I won't). ## Features - Covers 2" to 5" Pistons – Compress piston rings quickly and easily for pistons ranging from 2 to 5 inches in diameter. - Secure Ratcheting Lock – Built-in ratcheting mechanism holds tight during installation and features a fingertip release lever for fast removal. - Slip-Resistant Design – Bottom nibs prevent the compressor from slipping into the cylinder bore during use. - Durable Construction – Crafted from high-quality materials for repeated use in engine rebuilds and repairs. - Mechanic-Tested Quality – Designed to meet or exceed ANSI standards; includes step-by-step instructions with usage photos. - For compressing rings on pistons 2-Inch to 5-Inch in diameter - Ratcheting lock mechanism with fingertip release lever - Nibs on bottom prevent compressor from sliding into cylinder - Lifetime Warranty ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Powerbuilt | | Included Components | Powerbuilt Piston Ring Compressor, 2 Inch to 5 In | | Maximum Power | 0.2 Horsepower | | Power Source | Corded Electric | | Special Feature | Portable | ## Product Details - **Brand:** Powerbuilt - **Recommended Uses For Product:** Piston Installation - **Power Source:** Corded Electric - **Special Feature:** Portable - **Included Components:** Piston Ring Compressor (2" - 5") ## Images ![Piston Ring Compressor, 2 Inch to 5 Inch Diameter, Compress Pistons, Ratcheting Lock, Release Lever, Slide into Cylinder - 648433, Silver - Image 1](https://m.media-amazon.com/images/I/61axQ1WmfBL.jpg) ## Questions & Answers **Q: Will this work on a arctic cat 90cc** A: I don't know 100%, it worked on my 8 Hp Briggs & Stranton, the piston was probably around 2 3/4" dia. **Q: Will this tool work on a Briggs and Stratton walk-behind lawn mower engine?** A: I used it on a 5 hp tecumseh with no problems as long as the minimum size of the ring compressor is smaller than the piston it will work fine.
