Description

The National 99298 is a rear crankshaft repair sleeve designed to repair damaged, grooved, or worn shafts. It features a durable stainless steel construction for a corrosion-free sealing surface. The ultra-thin construction allows the original seal size to be used with minimal additional lip loading. Installation is made easy with a removable flange and a tool that reduces sleeve distortion.
