Cessna 152 Landing gear

1. LANDING GEAR: The aircraft is equipped with a fixed tricycle landing gear, consisting of tubular spring-steel main gear struts, and an air/oil steerable nose gear shock strut. Two piece, die-cast aluminum wheels are installed on the main and nose landing gear. The wheels are equipped with tubes and disc-type brakes. The nose wheel is steerable with the rudder pedals up to a maximum pedal deflection, after which it becomes free-swiveling up to a maximum of 30 degrees, each side of center. Nose and main wheel fairings are available for installation.
2. MAIN LANDING GEAR: The tubular, spring-steel main landing gear struts are attached to the aircraft at inboard and outboard forgings, located in the belly of the aircraft. A bracket is bonded to each strut for attachment of a step. Hydraulic brake lines are routed down and clamped to each main gear strut. The axles, main wheels and brake assemblies are installed at the lower end of each strut.
3. NOSE GEAR: A steerable nose wheel, mounted in a fork attached to an air/oil (oleo) shock strut make up the nose gear. The shock strut is secured to the tubular engine mount. Nose wheel steering is accomplished by two spring-loaded push-pull tubes linking the nose gear steering collar to the rudder pedal bars. A hydraulic fluid-filled shimmy dampener is provided to minimize nose wheel shimmy. A nose wheel speed fairing may be installed on some aircraft
4. SHIMMY DAMPENER: The shimmy dampener provided for the nose gear offers resistance to shimmy by forcing hydraulic fluid through small orifices in a piston. The dampener piston shaft is secured to a stationary part and the housing is secured to the nose wheel steering collar which moves as the nose wheel is turned right or left, causing relative motion between the dampener shaft and housing.
5. REMOVAL. a. Remove cotter pin, nut, washers and bolt attaching piston rod clevis.
b. Remove cotter pin, nut, and spacer and bolt attaching housing to steering collar.

6. DISASSEMBLY AND REASSEMLY: When reassembling dampener, install all new O-rings. Lubricate all parts with clean hydraulic fluid.
