CHAPTER 10
AXLES AND DRIVE LINES
BDAR FIXES SHALL BE USED ONLY IN COMBAT
AT THE DISCRETION OF THE COMMANDER
AND SHALL BE REPAIRED BY STANDARD MAINTENANCE PROCEDURES
AS SOON AS PRACTICABLE AFTER THE MISSION IS COMPLETED.
Section I. GENERAL
10-1.
GENERAL
Tactical wheeled vehicles need their axles and drive lines to be in good running
condition to perform a combat mission at full capacity.
Broken or damaged axle
shafts and drive lines are the most frequent causes of running gear and axle
malfunctions.
Carrier or third member failure is not as likely to happen; but if
it does, the rear axle carriers on the 5-ton trucks and 2-l/2-ton trucks are
interchangeable within the same series.
If 100% efficiency is not needed, the
following procedures will explain how to isolate a damaged axle, carrier, axle
shaft, or drive line so that the vehicle can be used in a degraded capacity.
