M2/M3 BFV:
STEERING SYSTEM - OD1605 - LESSON 1/TASK 1
make sure that the necessary equipment conditions are met. For this
procedure,
SGT
Fields
gets
a
general
mechanic's
tool
kit:
automotive, a woodruff key, cotter pin, two self-locking nuts, and
the STE-M1/FVS (VTM only). To set the equipment conditions, he must
make sure that the engine is stopped, the turret is shut down, and
the FIRE SUPPRESSION switch is in the MANUAL position. As references
for this procedure, he obtains TM 9-2350-252-10-1 and TM 9-2350-252-
10-2.
SGT Fields has completed the initial
steps
and
is
now
ready
to
troubleshoot the steering system.
Step 1. The first step in troubleshooting the steering system is for
SGT Fields to rotate the steering yoke (1) to the right and to the
left, and then back to the center to check if the steering yoke is
frozen, hard to rotate, or sticking (see figure 6).

STEERING YOKE AND SHAFT.
Step 2.
SGT Fields finds that these symptoms do not exist on the
vehicle, so he rotates the steering yoke to the right to determine if
the steering yoke will return to the center when released.
Step 3.
The steering yoke does not return to the center when
released, so SGT Fields checks for a faulty steering shaft by holding
onto the steering shaft (2) and rotating the steering yoke (1) to the
right and to the left (see figure 6).
