National Axle Differential Repair Sleeve,Engine Camshaft Repair Sleeve P/N:99146
Give a worn shaft a fresh surface for its oil seal to ride on with the National Oil Seal Repair Sleeve 99157. It is designed as a direct-fit repair sleeve for many vehicles, among them the 1983-2018 Honda Accord (including the 2018 L4-1.5L) and 1997-2014 Honda CR-V. See the Buyer's Guide tab for the full list.
A repair sleeve installs over the area of a shaft where the seal lip has worn a groove. It gives the seal a new contact surface and is designed to let the original shaft stay in service instead of being replaced. If a grooved seal surface is behind a recurring oil leak, this sleeve is intended to address that worn area when it is fitted together with the shaft's seal.
