GROVE AXLE CAMBER ADJUSTMENT SHIMS

2. Chalkline the center-line of the aircraft onto the floor. Do this by connecting a mark on the floor from directly beneath the center of the firewall (use a plumb-bob) and from directly beneath the center of the tail (also using a plumb-bob).

3. Place a 36″ straight edge against the outside of the tire. It should be parallel with the floor and approximately centered on the wheel.

4. Make a mark on the floor directly beneath each end of the 36″ straight edge. Use a plumb-bob or square for this.

5. Measure and record distances D-1 and D-2. These are the distances between the marks in step 4 and the aircraft center-line.

6. Calculate Delta D, which is the difference between D-1 and D-2. Delta D changes by 0.157″ for each 1/4″.

To Change Delta D by 0.10″ – 0.25″ Use 1/4″ Shim
To Change Delta D by 0.25″ – 0.40″ Use 1/2″ Shim
To Change Delta D by 0.40″ – 0.55″ Use 3/4″ Shim
