FAQs for "Stabilizer Jack Screw Actuator Kit"
Frequently Asked Questions
My Cessna 180/182/185 stabilizer trim is hard to turn or jams. How do I fix it?
Clean the barrel and screw jack and re-apply a coating of MIL-PRF-23827 low temperature grease. The cam bushings that attach the jack screws must be properly adjusted so that both jack screw work as one unit. If the cam bushings are not adjusted correctly the jack screws can work against themselves causing a hard to turn situation. Please review the complete instructions.
Stabilizer Jack Screw Actuator Kit
Stabilizer jack screw actuator kit part number 1111 is an FAA-PMA/STC approved kit to replace all wear components for the stabilizer actuator assemblies for many Cessna 180, 182 and 185 aircraft.
Improved material for extreme corrosion resistance
McFarlane replaces the original steel components with duplex stainless steel (even better than monel) components for a long life even in a harsh saltwater environment.
- Wear and vibration resistance for longer life
- No rust, even in salt water
- Costs less than the standard parts
Now improved with a Black Max™ nitrocarburized screw assembly to reduce friction and extend service life!
Ultra-precision bearing with no backlash
Improved Bearing
Precision bearing reduces free play and features extra low temperature grease for easy turning at low temperatures.
Improved Strength and Reliability
The original Cessna actuators use a 3/32" roll pin to attach the sprockets and retaining collars to the screw bars. These pins are critical as the front of the stabilizer would detach from the airframe if they failed. Although the original roll pins are technically strong enough, due to the nature of roll pins, they are prone to unpredictable failure. This is especially true if they are bent or damage during installation. To provide a more robust design, McFarlane redesigned the sprocket and retaining collar to allow the use of a 5/32" roll pin. This more than doubles the strength of the design. The screw and barrel are match machined for a precision fit.
