These are the key components in the Weight Shift Control Aircraft ROTAX 912 Engine:
- Integral gearbox.
- Fuel pump mechanically driven off the gearbox.
- Oil pump mechanically driven off engine camshaft.
- Oil pressure sender.
- Oil cooler.
- Radiator for engine cylinder head coolant.
- BING constant velocity carburetors which automatically adjust for altitude (also called constant depression).
- ROTAX air box (optional) which allows for carb heat and external combustion air inlet.
- External oil tank where oil is stored. Drain oil by removing bottom screw.
- Regulator/rectifier converting engine generated AC to 14 volts DC to charge battery for aircraft 12 volt DC system.
- Coolant recovery bottle (typically 1/3 full when cold).
- Air shroud for additional cylinder head cooling (optional).
- Oil cooler with fittings preferred on top.
- Airframe air box with carb vent line properly attached to air box.
- Battery, regulator/rectifier and starter solenoid grouped together.
- Cabin heat exhaust muff (optional) from ram air intake.
- Cooling expansion tank with overflow bottle mounted low (preferred to eliminate possibility of cooling fluid being siphoned out while checking).
- Gascolator for sediment and water separation from fuel.
- Gascolator recommended fuel filter inside engine compartment.
