ALIGNMENT OF MAIN LANDING GEAR. (Refer to Figure 32-4.)

1. Place a straightedge no less than twelve feet long across the front of both main landing gear wheels. Butt

the straightedge against the tire at the hub level of the landing gear wheels. Jack the airplane up just high

enough to obtain a six and one-haU inch dimension between the centerline of the strut piston and the

centerline of the center pivot bolt of the gear torque links. Devise a support to hold the straightedge in this

2. Set a square against the straightedge and check to see if its outstanding leg bears on the front and rear side

of the brake disc. (It may be necessary to remove the brake assembly to have clear access to the disc.) If it

touches both forward and rear flange, the landing gear is correctly aligned. The toe-in for the main landing

gear wheels is 0 ± 1/2 degrees.

A carpenter's square, bccause of its especially long kgs, is recommended for checking

main landing gear wheel alignment.

3. If the square contacts the rear side of the d isc. Ieaving a gap between it and the front flange, the wheel is

toed-out. If a gap appears at the rear flange, the wheel is toed-in.

4. To rectify the toe-in and toe-out condition, remove the bolt connecting the upper and lower torque links and

remove or add spacer washers to move the wheel in the desired direction. Refer to the Toe-in. To e - o u t
