Abstract
An engine includes a gear train to provide engine timing. There is a technique for minimizing the backlash and noise caused by the gear train. There is also an anti-backlash gear assembly useful to reduce backlash in the gear train. One gear assembly has at least two gear wheels with the circular thickness of the teeth of one gear wheel being less than the circular thickness of the other gear wheel. There is also a gear assembly having a bias torque of at least about 100 foot-pounds. There is also a device carried on an anti-lash gear assembly to generally align teeth of the assembly for installation.
