CONSTRUCTION
A cycloid rotor type oil pump is used. This oil pump is integrated with the timing chain cover.
This oil pump is directly driven by the crankshaft.
Ordinarily, the timing chain cover with oil pump construction has only a single position for mounting the oil pump rotor to the crankshaft, when installing the timing chain cover. However, in this engine, the inner shape of the oil pump rotor and the shape of the area of the crankshaft on which the rotor is mounted have been designed to provide 4 different assembly patterns. Thus, the serviceability for assembling the timing chain cover has been improved.
