ABSTRACT:
A kit for converting the rotatable supporting structure for an intermediate gear employed in a gear box or transfer case such as those used in certain commercially available four wheel drive vehicles and the like from a loose needle bearing support for journaling the intermediate gear from its supporting shaft to a tapered roller bearing support with the kit including a pair of tapered bearing assemblies, a spacer positioned therebetween, bushings received in the transfer case bosses, thrust washers between the bushings and the bearings and a bolt-type shaft having a polygonal head at one end and a lock nut at the other to retain the components in assembled relation and to preload the bearings in the intermediate gear by applying a predetermined torque on the lock nut while holding the bolt stationary. The kit enables conversion from loose needle bearing assemblies for the intermediate gear to a tapered roller bearing arrangement without any modification whatsoever to the transfer case or the intermediate gear which results in reduction of friction and noise at high rotational speeds and enabling less expensive replacement as compared to the loose needle bearing arrangements.
