  • Overload coupling
    Patent number: 7204337
    Abstract: A drive assembly for a vehicle having at least one wheel and an engine is disclosed. The drive assembly transfers a driving force from the engine to the at least one wheel. The drive assembly includes a rotatable input drive shaft. The input drive shaft is operatively coupled to the engine. The drive assembly further includes a rotatable output drive shaft. The output drive shaft is operatively coupled to the at least one wheel. A first transmission operatively connects the input and output drive shafts. An overload clutch is operatively disposed between the input drive shaft and the first transmission to transfer a driving force from the input drive shaft to the first transmission. The overload clutch may be at least partially mounted to input drive shaft.

  • Lubrication system for a four cycle engine
    Patent number: 6848528
    Abstract: A dry sump lubrication system for a four cycle engine is disclosed. The dry sump lubrication system has at least two lubricant storage chambers. A first lubricant storage chamber stores a first volume of lubricant. The first lubricant storage chamber may be located in a lower part of the crankcase. A second lubricant storage chamber is an oil tank and stores a second volume of lubricant. The oil tank may be secured to the output end of the crankcase. The first lubricant storage chamber is capable of storing at least 30% of a total volume of lubricant within the dry sump lubrication system.
