Instead of injuring your hands or using band styles that have no easy way to remove, the ABN Small Engine Ring Compressor Tool 7-Piece Set clamps down to hold ring in place and releases when the piston is reinstalled. They can also be used in engine applications where the cylinder is slipped over an assembled piston because the band can be opened and spread to remove after use. Big blocks and small blocks can be used with this set, and the small engine piston ring installer bands can also be used as motorcycle ring compressor tool bands. Package includes 6 bands from 2-7/8 to 4-3/8 inches (73-111mm) in diameter and a ratcheting pliers inside a storage case. To prevent the risk of scratching the cylinder bores, we recommend installing one at a time (not intended for 2 pistons at same time).
