LUBRICATION SYSTEM DETAILS


  1. CONSTRUCTION


    1. Oil Pump


      1. A compact cycloid rotor type oil pump directly driven by the crankshaft is used.

      2. This oil pump uses an internal relief method which circulates relief oil to the suction passage in the oil pump. This aims to minimize oil level change in the oil pan, reduce friction, and reduce the air mixing rate in the oil.

    2. Oil Strainer


      1. A low engine height is achieved due to the use of a light and compact oil strainer made of resin.

    3. Oil Nozzle Sub-assembly


      1. Oil nozzles are provided on the left side of the cylinder block for cooling and lubricating the pistons.

      2. These oil nozzles contain a check valve to prevent oil from being fed when the oil pressure is low. This prevents the overall oil pressure in the engine from dropping.

    4. Oil Filter


      1. An oil filter with a replaceable oil filter element is used. The oil filter element uses a high performance filter paper to improve filtration performance. It is also combustible for environmental protection.

      2. An aluminum alloy filter cap sub-assembly is used to extend its life.

      3. This oil filter has a structure which can allow the draining of the oil remaining in the oil filter. This prevents oil from spattering when replacing the oil filter element and allows the technician to work without touching hot oil.

        Tech Tips


        • The oil in the oil filter can be drained by removing the drain plug and inserting the drain pipe supplied with the oil filter element into the oil filter. For details, refer to the Repair Manual.

        • The engine oil maintenance interval for a model that has a replaceable oil filter element is the same as that for a conventional model.
