Abstract
An oil seal mounting jig for mounting an oil seal in a hole formed in the wall of a machine housing, the oil seal being provided on the inner periphery thereof with an annular oil-side tapered surface for contact with the oil to be sealed and an air-side tapered surface having an inclination angle greater than that of the oil-side tapered surface. The oil seal mounting jig has a hollow insertion cylinder opened at its one end and closed at its other end. A hub member for carrying the oil seal is adapted to be slidingly received by the cylinder from the open end of the latter and has an outer peripheral surface of an outside diameter substantially equal to that of a shaft on which the oil seal is to be mounted, one end surface of the hub member having a chamfered portion adapted to abut the oil-side tapered surface of the oil seal. The jig further has a spring disposed between the hub member and the closed end surface of the cylinder and adapted to urge the hub member outwardly of the cylinder, and a stopper for preventing the hub member from coming off from the cylinder due to the urging by the spring.
