REMOVAL & INSTALLATION
A conventional oil pump, which is chain driven, circulates oil through the rotary engine. A full-flow filter is mounted on the top of the rear housing and an oil cooler is used to reduce the temperature of the engine oil.
An unusual feature of the rotary engine lubrication system is a metering oil pump which injects oil into the float chamber of the carburetor. Once there, it is mixed with the fuel which is to be burned, thus providing extra lubrication for the seals. The metering oil pump is designed to work only when the engine is operating under a load.
Oil pump removal and installation is contained in the Engine Overhaul section above. Perform only those steps needed in order to remove the oil pump.
