ABSTRACT:
An engine of the V-type employing camshaft drive trains each including the crankshaft, two idle gear wheels held within a gear retainer and overhead camshafts. The idle wheels are of increasing diameter from the crankshaft to the camshafts. A transmission main shaft is placed relatively close to the crankshaft because of this arrangement. A backlash adjustment mechanism is employed with the mounting provided by the gear retainer. An eccentric journal portion of an axle allows adjustment through angular adjustment of the axle. A spring mechanism may provide appropriate torque on the eccentric axle mechanism to properly control backlash. Once properly positioned, the mechanism may be locked in place for normal engine operation.
