1986 Mazda B2000 Oil Pump Parts and Q&A
Q: What are the features and functions of the oil pump in a rotary engine lubrication system on 1986 Mazda B2000?
A: A conventional oil pump, which is chain driven, circulates oil through the rotary engine, with a full-flow filter mounted on the top of the rear housing and an oil cooler to reduce the temperature of the engine oil. An unusual feature of the rotary engine lubrication system is a metering oil pump that injects oil into the float chamber of the carburetor, where it mixes with the fuel to provide extra lubrication for the seals, functioning only when the engine operates under a load. Removal and installation of the oil pump involves performing only the necessary steps to take out the oil pump.
