SERVICE MANUAL & I.C.A. FOR THE 7000 AMPHIBIOUS FLOATS

Revision G Page 41 of 102 P/N 1004646 Doc. No. W7001-24-01

4.1 MAIN GEAR RETRACTION

DESCRIPTION

Refer to Figures 4-1, 4-2, 4-3, 4-4A, 4-4B, 4-5
and 4-6 for visual reference.

Retraction and extension of the main gear is

accomplished with a hydraulic rack and pinion

type actuator. The actuator consists of two

opposing pistons connected by a geared rack,

with a rotating pinion gear in the middle.

Hydraulic fluid is transferred from one piston

to the other using an electrically reversible

hydraulic pump located in the empennage of

the aircraft. The differential pressure build up

causes the piston to move, pushing the rack

and rotating the pinion gear and its attached

drive shaft.

Attached to each end of the drive shaft are

actuating arms that drive separate rod linkages

with adjustable rod ends. The drive shaft and

actuating arms have a keyway to prevent

slippage on the rotating drive shaft. The rod

linkages push and pull on the Main Gear Top

Arm Assembly causing it to pivot around a

fixed point. Also attached to the actuators

drive shaft is a visual gear position indicator.

This indicator consists of colored bands that

rotate with the drive shaft allowing the pilot to

visually determine the position of the main

landing gear by looking at a placard on the

deck of the float.

Since the actuator rotates through

approximately 193 degrees, the rod

linkages and the actuating arm pass an over

center point, preventing reverse driving of

the rack and pinion actuator in both the

fully extended and fully retracted positions.

The actuator rotation is adjusted by

setscrews that determine the length of

travel of the actuator pistons. Providing

an over center up-lock prevents inadvertent

main gear extension in the case of a

hydraulic failure.

As a secondary safety to ensure the

geometry remains over center with a

hydraulic failure, a spring is installed on

the actuating arm preventing motion of the

rack and pinion actuator. Since the

retraction mechanism is over center, the

weight of the landing gear and oleo, when

retracted, also prevent the retraction

mechanism from rotating past the over

center point.
