M2/M3 BFV:
STEERING SYSTEM - OD1605 - LESSON 1/TASK 1
Step
4.
While performing step 3, the steering shaft did not turn
with
the steering yoke. SGT Fields must now remove the steering yoke
from
the steering shaft as described in Step 4 of paragraph 5e(2) on
page
32.
Step 5.
After removing the steering yoke, the steering shaft is
visually checked for a damaged or missing woodruff key.
On this
vehicle, SGT Fields finds that the woodruff key is damaged and must
be replaced.
Step 6.
He installs a new woodruff key into the steering shaft
(procedures for installation can be found in Step 2 of paragraph
5e(3) on page 34) and the vehicle is retested to verify that no
faults are found.
Step 7. After test operating the vehicle, SGT Fields finds that the
steering system still is not functioning properly and must be
troubleshot again. He performs Step 1 again by rotating the steering
yoke to the right and the left, and then back to the center.
The
steering is not frozen, hard to rotate, or sticking so he performs
Step 2.
Step 8.
Step 2 instructed him to rotate the steering yoke to the
right and then release it to check if the steering yoke would return
to center.
Unlike the previous troubleshooting, the steering yoke
does return to center after being rotated to the right.
Step 9. SGT Fields is now asked in the troubleshooting procedure if
the transmission lubrication system troubleshooting has been done.
For this example, it will be assumed that this troubleshooting has
been done.
Step 10. The STE-M1/FVS (VTM only) is now hooked up to jack 1A1J14
or 1A1J15 (DCA 3 or DCA 13) as described in paragraphs 3b and 3c on
pages 4 through 9 to perform TEST NO. 10 ENGINE RPM (IDLE) which was
described in paragraph 3d on page 9.
Step 11. After performing Test NO. 10, SGT Fields leaves the engine
running and releases the hand brake. He then moves the gear selector
(1) to PIVOT STEER to see if the engine will stall (see figure 7 on
the following page).
