An apparatus is disclosed for aiding in the speed and simplicity of the adjustment of the clicker-style cam bolts employed by TRA-type snowmobile drive clutches, manufactured by Bombardier Recreational Products. The apparatus comprises a barrel type nut with a collared head and a compression wire spring which fits telescopically over said nut and against said collared head, and a locking set screw to secure the apparatus against rotational movement or removal. This assembly replaces the conventional hexagonal lock nut presently used on TRA-type drive clutches. This apparatus enables the user to change the linear position of the cam bolt in the drive clutch housing to enable the hexagonal head of the clicker-style bolt to clear its respective hexagonally indexed pocket, which is molded into the drive clutch housing, and to be turned to any one of six different degrees of rotation, thereby changing the shift-out RPM setting of the drive clutch quickly and with greater ease than conventional methods.
