Figure 95-1. Tire Balancer Fixture
TIRE BALANCER BUILDING INSTRUCTIONS.
1. Chamfer top edges of -3 sides, leaving 1/16 inch flat on top inboard edge. Rivet -2 tee’s to -3 sides
using AN 470-AD5 rivets 2” spacing. Use AN 426-AD5 rivets 2” center to center to secure -2 tee’s to -1 base.
If tee extrusion is unavailable, heavy angle extrusion could be used. -3 sides must be vertical.
2. The -4 axle must slide through the -8 pipe. The -5 nuts were made by reaming the existing threads in
the AN 365-624 nuts with an R drill, then tapping with a 1/8-27 pipe tap.
3. The -6 spacers were made from 1/2 inch aluminum tubing. The two lengths of spacers are suitable for
balancing most any aircraft wheel.
4. The -7 bushings may be made from one inch phenolic or aluminum using a 1-1/2 inch hole saw to cut
out the smaller bushing and a 1-3/4 inch hole saw to cut out the larger. By inserting a 1/4 inch long threaded
bolt through the pilot hole and securing with a washer and nut, a drill press and file may be used to make the
off-set on the bushing. The turned-down part should just slide inside the bearing race. Ream the pilot hole to
slide over the -8 pipe threads.
5. The -8 pipe was made from a piece of 1/8 inch black pipe and threaded with a 1/8-27 pipe die. Thread
3 inches in from each end of the pipe.
