OIL PUMP CONSTRUCTION [MZR 1.6]
id0111s1100600
• The oil pump is directly driven by the crankshaft to reduce engine noise.
• A lightweight and compact trochoid gear type oil pump with excellent heat-resistant and noise reduction characteristics has been adopted. Due to this, oil discharge is stabilized.
• An efficient and compact trochoid gear type with 9.5 mm {0.37 in} wide rotors (inner rotor, outer rotor) has been adopted for the oil pump.
• The oil pump consists of the oil pump body, inner rotor, outer rotor, relief valve, and oil pump cover.
• An aluminum alloy oil pump cover has been adopted to reduce weight.
• The relief valve component, which adjust the oil pressure, is built into the oil pump body.
