ABSTRACT:
A tool and method by which an inner oil seal may be installed in the hub of a wheel assembly which is in a normal upright position. The tool comprises a shaft with a tool mounting plate affixable to the outer end of a hub with the tool shaft extending axially therethrough and terminating in a threaded end. A seal locator and pusher is slidably mountable on said tool shaft from the threaded end thereof. The locator and pusher has a portion facing the tool mounting plate on which the inner seal may be slidably mounted. The opposite face of the locator and pusher is provided with a thrust bearing and thrust washer. The tool includes a nut engageable on the threaded tool shaft end. The wheel assembly is removed form its axle and is maintained in an upright position. The seal mounting tool is bolted to the hub. The inner oil seal is mounted on the locator and pusher which is mounted on the tool shaft from its threaded end. The nut is engaged on the tool shaft threaded end and tightened to cause the locator and pusher to properly and evenly seat the seal in the hub. The tool is thereafter removed from the hub and the wheel assembly is remounted on its axle.
