OIL PUMP CONSTRUCTION[MZ-CD 1.6 (Y6)]

id0111d2100600

•  The trochoid gear type oil pump is located at the timing gear end of the engine and driven by the crankshaft directly for noise reduction.
•  The oil pump consists of an oil pump body with a built-in relief valve, inner rotor, outer rotor and oil pump cover.
•  An aluminum alloy oil pump body has been adopted to reduce weight.
•  A pressure relief valve has been built into the oil pump housing.
•  An efficient and compact 9-lobe epitrochoid and 10-flank inner envelope type gear has been adopted for the oil pump.
•  The inner rotor has two flats which form a keyed connection with the crankshaft.
