Many years ago, the final drive for the M55, a 50 ton 500 horse power tracked vehicle, was redesigned and still failed. The cross drive transmission has splines that drive the pinions that drive bull gears that are on the same shaft as the sprockets that drive the tracks. An old man wants to know if there are now pre twisted spur gear pinions so, when highly loaded, a gear will be twisted straight. TIA
