2-19. Preparing Platform
Prepare a 24-foot, type V platform
as shown in Figure 2-22.
NOTES:
1. The nose bumper may or may not be installed.
2. Measurements given in this section are from the front edge
of the platform NOT from the front edge of the nose bumper.

Step:
1.
Inspect, or assemble and inspect, a 24-foot, type V airdrop platform as outlined in TM 10-1670-268-20&P/
TO 13C7-52-22.
2.
Install a tandem multi-purpose link to each platform side rail using holes 1, 2, and 3.
3.
Attach clevises to each tandem link using bushings 1, 2, (tripled), and 3.
4.
Starting at the front of each platform side rail, install clevises using bushings bolted to holes 5, 7, 16, 18,
19, 26 (doubled), 27, 28, 29, 30, 31, 38, 39, 41 (doubled), 42, 43, 44, 45, 46, 47, (tripled), and 48.
5.
Starting at the front of the platform, number the clevises 1 through 28 on the right side and 1A through
28A on the left side.

NOTE: On all stacks the plywood must be cut to fit lumber. EXAMPLE: An 11 1/2- by 24 inch piece of plywood
sits on a 2- by 12- by 24-inch piece of lumber but hangs over a 1/2 inch on the 11 1/2 inch side. Cut it to 11 by 24
inches to insure it fits. This is not due to improper measurements but to the fact that lumber varies in true sizes.
