Original factory machining cross-section of installer 304722 with dimensions and chamfer details
To install double lipped seal #305937, upper journal bearing, tool #304722 must be reworked to avoid damaging the upper rubber lip of the seal.
Reworking tools currently in dealers' possession is relatively simple and can be performed by the individual dealer or by a local machine shop. Simply chuck the tool in a lathe and machine according to the specifications furnished in the sketch above. Even though modified, the tool can still be used to install single lipped seals if and when required.
The parts depot's stock of this tool has been replaced with the modified unit so that all future shipments will consist of the modified tool, ready for use on both the double and single lipped seals.
The tool's part number remains unchanged and is priced at $.75 each, net, F.O.B. Galesburg, Illinois.
