Oil: Aeroshell 15W50 Max 8Qts. Min 7Qts. (best operating practice) Oil quantity on dip stick only accurate right after shutdown. Oil drains back into case. Has two oil pumps: Pressure pump to supply oil to bearings, Scavenger pump to return oil to tank. Oil cooler built into oil tank. Oil spills over and bypasses cooler when cold/thick, flows thru cooler when hot. Simple! Carburetor: Bendix PS-5C Pressure Carburetor First generation of fuel injection. Sprays fuel into intake manifold, instead of to each cylinder. Electric Standby fuel pump for loss of engine pump or to help with starting. Otherwise it's OFF. Hand pump to help with starting, and for last resort if engine pump and standby pump fail. Propeller: Hartzell hydraulic HC-A2X20 Original bonanza had electric prop. This prop is an aftermarket add-on. T-drive allows prop governor and fuel pump to attach to engine from same accessory drive gear. Loss of T-drive might result in loss of prop gov. and fuel pump. Oil is routed from prop gov. outside engine via an oil line to the Oil Transfer Unit. OTU injects oil into the propeller hub for operation. Oil pressure increases RPM, Counterweights and aerodynamic forces move blades to low RPM. If prop gov. fails, RPM will drop to around 1800 rpm at max power. Fuel: 2 Main Tanks in wings, 1 Aux Tank in baggage compartment 20 Gals. Total for each fuel tank. 17gals usable for each main tank. 19.5gals usable for Aux. Tank. Total of 53.5 gals usable. 100LL or 87 auto gas with no ethanol. Must not takeoff unless both main tanks are above yellow arc. (10gals in each tank min) Turning takeoffs not approved, since fuel might roll away from outlets. Pressure Carb returns fuel from any tank to the left tank at about 2 gals/hr at cruise settings. Left tank should be used first to prevent return fuel from overflowing the tank. Total of 4 fuel drains. Landing Gear: Nose Tire: 45psi, Strut extension 3.25” normal. Main Tires: 38psi, Extension 3.5” normal Nose Wheel centers during retraction, steering disabled. Electric motor drives gear box to push gear up or down using push rods. Pushrod springs maintain pressure on over-center downlock arms. Mechanical uplock arms hold gear UP in turbulence/G-loads. Hand crank can be used to lower gear but not retract. 50 turns CCW to extend. Original gear lights indicate motor position only. Green fully extended, Red fully retracted. Add-on gear lights (3 green) have microswitches on each gear leg. Inner gear doors open/close during gear movement. Nose wheel moves forward during extension. Beeping horn turns on at MP less than 12” with gear up. (no horn for flaps or gear switch position) Squat switch on right main gear prevents retraction on ground. (with gear strut compressed) Step retracts during nosewheel retracton via cable. Standby nose position indicator on floor has cable link to nose gear. Electrical: 14Volt/ 55 amp alternator. 12Volt battery in engine compartment. Do not operate alternator without battery, otherwise voltage regulator won't be working. Rudder and Ailerons: Spring interconnect. Helps with rudder coordination in turns. Cable and pulley system. Elevator and Rudder: V-Tail mixing unit uses combination of pushrods, cables and pulleys. Flaps: Electric motor and drive shaft system. 20 degrees. Max deflection. Mostly lift, very little drag. 0-20 approved for takeoff. The only flap indicator are markings outside on the left flap. Stall Warning: Steady horn and red light, when flying vanes on left wing drop to activate switch. Disabled on ground via squat switch. Autopilot: gets info from Turn Coordinator and Heading Bug on HSI and Nav 1 or 2. Vacuum driven servos to rudder and ailerons. No elevator input. Pulling knob turns on Basic Stability. Aircraft will right itself if control is lost by pilot. Turn Coordinator is both electric and vacuum driven. If electric fails, turn coordinator & basic autopilot stabilizer still work. If vacuum fails, turn coordinator still works, autopilot inop. Limitations Oil Temp: 225F Oil Pressure: Min:10psi (idle) 25psi (full power) Max: 65psi Cylinder Head Temp: 525 F Fuel Pressure: 9psi - 14psi Tachometer: 2650 RPM (for 1 minute) 2300 RPM Continuous Utility Category +4.4 G -1.76 G (+2.0 G Flaps Down) No acrobatics, No spins.
