Lesson 1/Learning Event 1
Unpacking.
See that the equipment is complete by checking it against the
packing list for each skid. See that the special tools and accessories are
with the equipment and that one hose-reel crank handle is in the toolbox.
Insure all publications are present. See that all markings comply with AR
746-1. Check that the metal-strap shipping-mount assembly in the pump-unit
assembly was removed by direct support maintenance personnel. The shipping-
mount assembly connects between the engine flywheel housing and the skid.
Check that the three engine shock mount pads are installed between the front
and rear engine mounts and the top of the front and rear channel assemblies.
If they are missing or are improperly installed, notify direct support
maintenance personnel.
Check that the tachometer cable, hose-reel pillow
blocks, and the fuel-hose assembly have not vibrated loose during transit.

Avoid
damaging the equipment. Use suitable equipment to lift the three skids from
