Towing the M915 thru M920 Trucks. (Cont)

TM 9-2320-273-10

NOTE

The purpose in disconecting and tieing up this shaft is to

prevent drive to the transfer case which would damage the

transmission output side without the benefit of oil pressure

lubrication which is provided from the engine driven input

side.

c. Rear Tandem Lifted Off the Ground

When the rear tandem axles are lifted off the ground by a wrecker and towed, it is

necessary to disconnect the universal joint at the front of the front propeller shaft

(at the input to the front axle) and tie it up to the vehicle undercarriage.

NOTE

The purpose of this (as stated above) is to prevent damage

to the transmission.

d. Towing Short Distances

It is permissible to tow the M916 thru M920 vehicles very short distances (up to 1/2

mile) at very low speeds (up to 10 mph) without disconnecting the driveline at all.

e. INSTALL MEDIUM DUTY TOWBAR (NSN 2540-00-378-2012) at pintle of towing

vehicle and at towing eyes of truck tractor. MAKE SURE TOWING DEVICE IS

LONG ENOUGH TO allow for complete turning radius.

f. To maintain a supply of air for brake operation, connect air pressure hoses between

the truck and the towing vehicle. Quick disconnect couplings are provided in the

bumper for this purpose.

g. PLACE TRANSMISSION IN NEUTRAL, RELEASE PARKING BRAKES, and turn

on appropriate lights.

h. TOWING VEHICLE SPEED SHOULD BE RESTRICTED TO A MAXIMUM OF

15 MPH ON PRIMARY ROADS AND 8 MPH ON SECONDARY ROADS. For

cross-country towing, all tires should be on ground.
