Sirio Precision Bearing Installer Tool

Sirio’s crankshaft bearing installer tool is made to ensure the best possible alignment of the crankshaft bearings during installation. This Sirio tool is one of the few that presses the bearing in from the outside race. Many other tools apply pressure to the inside race of the bearings, which can sometimes damage the bearings before they’re ever used. This precision tool comes with a lightweight milled aluminum handle, which can be removed for more compact storage and transportation. The front boss features a smooth one-way bearing, which means the bearings are pressed straight in, no twisting motion from the tool to misalign the bearing, meaning the best possible installation every time. Two models are available, one for big-block engines and one for small block engines.
