TM 9-2520-272-40 0069 WARNING When rotating transmission from vertical to horizontal position, the weight of transmission is transferred from one sling to the other. When the center of gravity shifts, transmission may suddenly tilt, thrusting heavy momentary stress on sling, hoist, and trestle. To avoid injury or death, keep out from under and clear of transmission at all times. Check condition of slings; replace as necessary. Stay clear of slings. Do not get under transmission. CAUTION Either sling, or both slings, should be raised as necessary to maintain at least one foot clearance between transmission and f oor. The transmission will be damaged if it hits the f oor when weight shifts from one sling to the other. 17.(Soldier 1) Using hoist and trestle, slowly raise engine and transmission sling (Figure 23, Item 20). 18.(Soldier 2) Using hoist and trestle, raise multiple-leg sling (Figure 23, Item 12) as necessary to maintain proper clearance between transmission (Figure 23, Item 15) and f oor. 19.Using hoist and trestle, raise engine and transmission sling (Figure 23, Item 20) slowly until entire weight of transmission (Figure 23, Item 15) is on engine and transmission sling. 20.Remove multiple-leg sling (Figure 23, Item 12) from transmission (Figure 23, Item 15). 21.Lower transmission (Figure 23, Item 15) slowly to work table or f oor. Remove hooks of engine and transmission sling (Figure 23, Item 20) from transmission. 0069‐18
