bolted on holes 5, 15, 20, 21 and 25.
6. Install a clevis on bushing 17 in an inverted position. Install a clevis on bushing 17A in the normal
position. Bolt an additional clevis to each of the clevises on the 17th bushings.
7. Starting at the front of the platform, number the clevises bolted to the right side of the platform
from 1 through 9, and those bolted to the left side from 1A through 9A. Number the clevises
bolted to the 17th bushings 5 and 5A. Number the clevises bolted to these clevises 4 and 4A.

PREPARING TRUCK
2-4. Prepare the truck as described below.
a. Make sure the fuel tank is no more than 3/4 full. Prepare the fuel tank

is 95% full is to fill the tank and withdraw 1 1/4 gallons with a hand pump.
CAUTION
A full tank does not allow for fuel expansion,
and is a danger to aircraft and crew.
b. Make sure the batteries and battery compartment comply with AFJMAN
24-204/TM 38-250.
c. Stow the truck OVE according to TM 9-2320-280-10/TO 36A12-1A-2091-1/
