Deck sling needs adjustment.

Mechanics, if you've got a damaged oil fill tube or tray on your M88A2 recovery vehicle, chances ate you were a little sloppy when removing of installing the engine deck.

If you're not careful or use the wrong lifting equipment, the engine deck can easily smack into the oil fill tube or tray. The oil fill tube is especially vulnerable.

The upper oil fill tube is connected to the lower tube by two O-rings. When the upper fill tube is bumped or hit by the deck assembly, the O-ring seal is damaged and a leak occurs. If enough oil leaks out, you're looking at major damage to the engine.

The right way to remove the engine deck assembly means using the modified sling assembly, NSN 3940-01-440-0283.

This sling can be adjusted for several different lift capabilities by sliding the cross beam up of down and locking it into the correct setting. When lifting the engine deck assembly, make sure the sling is adjusted to the ENG DECK M88A2 setting. Then use extra care to avoid hitting the oil fill tube and tray.

It's also a good idea to empty the on-vehicle equipment (OVE) box when removing or installing the engine deck. The tools and equipment stored in the OVE box can shift and cause an uneven lift of the deck.
