To remove a stepped sleeve, inject oil or an SKF dismounting fluid between the sleeve and shaft using suitable oil injection equipment (→ Oil injection equipment and pressure media). When sufficient oil pressure has been built up to separate the mating surfaces, an axial force will result due to the different bore diameters, and the sleeve will slide from its seat without requiring any additional external force.


To avoid the risk of serious injury, attach a provision such as a lock nut to the shaft end to limit the sleeve travel when it suddenly comes loose.
