ADJUSTMENT OF NOSE GEAR UP LIMIT SWITCH.
The gear up limit switch is mounted on a bracket on the engine mount above the point where the right side
of the upper drag link attaches to the engine mount.
1. To facilitate adjustment of the limit switch, disconnect the gear doors or remove the bottom cowl, as
desired.
2. 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 position
and turn the master switch off.
3. Block the nose gear in the up position and then slowly release the emergency extension lever. This will
relieve hydraulic pressure and the main gears will drop.
4. Place a .027 of an inch spacer on the oleo strut housing between the housing and the crossover tube
where the steering arm attaches. Push the gear up tight and block.
5. Loosen the attachment screws of the switch and rotate the switch toward the actuator tank until it is
heard to actuate. Retighten the attachment screws of the switch.
6. Manually move the gear up and down only as far as necessary to ascertain that the switch actuates at
the correct position. Remove the block from under the gear and allow it to slowly extend.
