SUBJECT:  DO-IT-YOURSELF HOLDING TOOL

Have you ever tried to figure out an easy way to hold the V-4 Starter Bendix Drive, for the purpose of loosening or torquing the nut on the gear and shaft assembly. I know you have.

Don't fight the operation any longer, and possibly do it by the wrong method of inserting some object between the flywheel ring gear and Bendix Drive. This method can damage the gear teeth and very possibly distort the Bendix housing.

This operation can be handled very easily by making up an inexpensive do-it-yourself special tool. The tool is made from one of the regular Tool Kit type screwdrivers to the dimensions shown. (Figure #1).

Figure #2 illustrates application of the tool in loosening the nut.

Figure #3 illustrates application of the tool in torquing the nut.

NOTE: The flywheel need not be removed for these operations. It has been removed in this instance for the sake of better illustration.
