rolled steel exactly 7-5/64" long with a 3/16" hole
drilled 1" deep at each end. The purpose of the dummy
shaft is to retain in position the needle rollers, sleeve and
thrust washers when removing or Installing counter-
shaft gear cluster.

contact with the countershaft during this operation,
otherwise the thrust washers, needle rollers and other
parts will fall out of place.
