Oil Pump

Trochoid pump driven by engine shaft. The pump is mounted externally on the case and is considerably larger than the P410 pump since the transaxle relies primarily on oil cooling. There are two oil distribution tubes within the transaxle that distribute oil from the oil pump to oil directors mounted on the end windings of both MG1 and MG2.[2]
