Abstract
Abstract A tool for installing and removing a seal retainer of the type found on the drive axles of certain front wheel drive automobiles. The tool comprises a C-ring for engaging a seal retainer and a crossbar parallel to the C-ring. A pair of spacers are rigidly attached to and between the C-ring and crossbar to form a frame. A thumbscrew is operatively positioned in a threaded hole through the crossbar for engaging a shaft while installing or removing a seal retainer. The crossbar of the tool is tapped with a mallet to apply the force which is necessary to remove a seal retainer. The force which is necessary to install a seal retainer is applied by tightening the thumbscrew.

Claim 1
Independent Claim
198 words
A tool for installing and removing seal retainers of the type used in connection with constant velocity joint assemblies and associated outboard seals on the drive axles of front wheel drive automobiles, comprising: an essentially flat C-ring for engaging the seal retainer to be installed or removed, said C-ring being provided with a recessed portion along its circumference and an opening there through which is no larger than necessary for positioning said C-ring around the shaft of the constant velocity joint assembly with which the seal retainer to be installed or removed is associated such that said recessed portion of said C-ring engages said seal retainer along essentially its entire circumference; an essentially flat crossbar positioned parallel to said C-ring; a pair of identical, parallel, elongated spacers positioned perpendicular to and between said C-ring and said crossbar, each of said spacers having one of its ends attached to said C-ring and the other of its ends attached to said crossbar; and a thumbscrew operatively positioned in a threaded hole through said crossbar for engaging the free end of the shaft of the constant velocity joint assembly with which the seal retainer to be installed or removed is associated.

A tool for installing and removing seal retainers of the type used in connection with constant velocity joint assemblies and associated outboard seals on the drive axles of front wheel drive automobiles, comprising: an essentially flat C-ring for engaging the seal retainer to be installed or removed, said C-ring being provided with a recessed portion along its circumference and an opening there through which is no larger than necessary for positioning said C-ring around the shaft of the constant velocity joint assembly with which the seal retainer to be installed or removed is associated such that said recessed portion of said C-ring engages said seal retainer along essentially its entire circumference; an essentially flat crossbar positioned parallel to said C-ring; a pair of identical, parallel, elongated spacers positioned perpendicular to and between said C-ring and said crossbar, each of said spacers having one of its ends attached to said C-ring and the other of its ends attached to said crossbar; and a thumbscrew operatively positioned in a threaded hole through said crossbar for engaging the free end of the shaft of the constant velocity joint assembly with which the seal retainer to be installed or removed is associated.
Claim 3
Dependent Claim
85 words
A tool as recited in claim 1, further comprising an essentially flat C-ring adaptor which nestles in said C-ring to adapt said tool for installing and removing a smaller sized seal retainer, said adaptor being provided with an opening there through which is no larger than necessary for positioning said adaptor around the shaft of the constant velocity joint assembly with which the seal retainer to be installed or removed is associated such that said adaptor engages said seal retainer along essentially its entire circumference.
Claim 4
Dependent Claim
96 words
A tool as recited in claim 1, further comprising an essentially flat C-ring adaptor which nestles in said C-ring to adapt said tool for installing and removing a smaller sized seal retainer, said adaptor being provided with a recessed portion along its circumference and an opening there through which is no larger than necessary for positioning said adaptor around the shaft of the constant velocity joint assembly with which the seal retainer to be installed or removed is associated such that said recessed portion of said adaptor engages said seal retainer along essentially its entire circumference.
