2-62. Emergency Control for AHEAD Only.

a. If the pressure oil supply fails, emergency control is possible with the aid of hexagon screw K 8.

b. For this purpose, the engine must be shut down. Upon removal of the locking wire, the hexagon nuts

K 9, hexagon screws K 8 are to be tightened while the clutch is being rotated evenly. This results in the disc

packet being pressed together and the disc clutch becoming force-locked.

c. It is necessary to ensure that, during emergency control, only the AHEAD clutch is blocked. In the

case of gearboxes with AHEAD output direction of rotation against the input (engine) direction of rotation, this is

the clutch on the input shaft W 1. If input and AHEAD output directions of rotation are identical, the clutch

fitted to the intermediate shaft W 20, arranged on the side, must be locked.

d. Before re-starting the engine, the gearbox control lever must be shifted to STOP. It must not be

shifted to ASTERN, as this would block the gearbox.

e. Location of K 8, K 9, W 1, and W 20 may be found in TM 55-1905-223-24P-1: Page 43-2 for items

48, 49, and 79; Page 44-1 for items 17 and 18; and page 44-2 for item 48.
