ADJUSTMENT OF NOSE LANDING GEAR. (PA-28RT-201T) (Refer to Figure 32-7.)
The gear up stop is located on the gear mount approximately 6 inches above the aft attachment point of the
upper drag link.
1. Remove the engine cowl.
2. Place the airplane on jacks. (Refer to Jacking, Chapter 7.)
—NOTE—
Inspect the nose landing gear link and brace assembly, the aft
attachment end of the nose actuator and the right front hat
section fairing for cracks and loose rivets. Dye penetrant may be
required. If any of these parts are cracked, remove and replace in
accordance with the latest revision of Piper Service Bulletin No.
724.
3. Loosen the jam nut on the gear up stop, and turn stop in as far as possible.
4. Loosen the jam nut on the hydraulic actuator rod end bearing and disconnect from downlock hook.
5. Adjust rod end so that threads barely cover witness hole in the actuator rod end and reconnect actuator
to downlock hook.
6. Carefully retract the landing gear by turning the master switch on, raising the emergency gear
extension lever and moving the gear selector handle to the UP position. Retain the emergency extension lever
in the UP override position.
7. Ascertain that the actuator piston bottoms before any part of the gear mechanism contacts adjacent
parts. Place a carpenters square with the longest end along the bottom of the fuselage, and the shortest end
running up through the centerline of the wheel axle. At this time measure up along the square from the bottom
of the fuselage to 5.00 +/-.12 inches. At this location the dimension should read 5.30 to 5.50 inches. If not,
adjust piston rod end to obtain this range.
8. With gear in the retracted position, manually pull the tire down and adjust the gear up stop to obtain
5.00 +/-.12 inches and tighten jam nut.
9. Move gear selector handle to the DOWN position. With gear down and locked, check to ensure that
some additional actuator rod travel is available by removing rod end bolt and pulling the piston until it
bottoms.
10. Check to ensure that rod end threads cover witness hole in the actuator rod.
11. Tighten jam nut on rod end bearing and complete hookup of piston rod and bearing to downlock hook.
12. Cycle gear, including free-fall and final dimensional check of 5.00 +/-.12 inches.
13. Adjust shimmy dampener by turning nose wheel against stops and adjusting the rod end of the
dampener for adequate travel to both extremes.
14. Install engine cowling, retract landing gear and check door per Adjustment of Nose Gear Doors.
15. Ascertain that the gear is down and locked, then remove the airplane from jacks.
