Lifting Procedure

TTP B1-L1 ATA07 Cessna 172 B2-L1 Cessna 172 airplane may be lifted with a hoist of two-ton capacity attached by rings , which are optional  equipment installed by Service Kit, or by means of suitable slings.      Front sling should be hooked to  each upper engine mount, and the aft sling should be positioned around the fuselage at the first bulkhead  forward of the leading edge of the stabilizer. If the optional hoisting rings are used, a minimum cable  length of 60 inches for each cable is required to prevent bending of the eyebolt-type hoisting rings.  If  desired, a spreader jig may be fabricated to apply vertical force to the eyebolts PTP   Cessna 172 B1 LOC B2 LOC

Towing & Taxing

TTP B1-L1 ATA09 Cessna 172 B2-L1 Towing -   Moving the airplane by hand is accomplished by using the wing struts and landing gear struts as  push points.    Tow bar attached to the nose gear should be used for steering and maneuvering the  airplane on the ground.    When no tow bar is available , press down on the tailcone at a bulkhead to  raise the nose wheel off the ground. With the nose wheel clear of the ground, the airplane can be  turned by pivoting about the main wheels. CAUTION: WHEN TOWING THE AIRPLANE, NEVER TURN THE NOSE WHEEL MORE THAN  30 DEGREES EITHER SIDE OF CENTER , OR THE GEAR WILL BE DAMAGED. DO NOT PUSH  ON CONTROL SURFACES OR ANY PORTION OF THE HORIZONTAL STABILIZER. WHEN  PUSHING ON THE TAILCONE, ALWAYS APPLY PRESSURE AT A BULKHEAD TO AVOID  DAMAGING THE SKIN.                  PTP Cessna 172 B1 LOC SGH B2 LOC SGH

Attached to the outboard end of each strut is a die-cast aluminum wheel and disc brake assembly. Steering nose wheel that is linked through the rudder pedals to give ground control. Shock Strut - The shock strut is made of top and bottom machined cylinders that contain a mixture of oil and air. The top and bottom cylinders give changes in the shock-absorb rates. Torque Links - The torque links give a mechanical link between the top and bottom parts of the shock strut and help to keep the nose wheel aligned with the airframe. Nose wheel Steering - operates through the use of the rudder pedals. The spring-loaded steering rod assemblies connect the nose gear steering arm assembly to the arms on the rudder pedals. The steering gives up to approximately 10 degrees each side of neutral, aft

Shimmy Damper

Make sure that the shaft comes out through the filler hole until the damper is installed on the aircraft.   (6) Install the damper on the airplane.
