Abstract

An index torque measurement system is provided. The system includes a blocker ring and a source, of index torque. The source of index torque applies a varying amount of index torque to the blocker ring to allow smooth indexing of the blocker ring teeth with synchronizer sleeve teeth. The system includes a synchronizer sleeve drivable to overcome the index torque to engage the blocker ring. The system further includes a measurement system that measures the force to overcome the index torque based on a load required to drive the synchronizer sleeve into engagement with the blocker ring given the applied index torque.
