The locking pin and spring are wear parts of the tailwheel assembly. Eventually, they wear out and have to be replaced, or they accidentally get shot across the hangar and lost during maintenance. Order one here. Fits Screaming Eagle, Doug Bell, Van’s, JDAir, and similar tailwheels using a 1/4″ square locking pin.
Comes polished, profiled and ready to install. Includes pin and spring.
