STEERING TIME CHECK
0016 00
N OT E
Difference between time for right and leftturn must not be more than 0.3 seconds.
With parking brake engaged, steering time must not increase by more than 0.2 seconds.
1.
Start engine (TM 5-3805-291-10).
2.
Disengage parking brake (TM 5-3805-291-10).
3.
Run engine at high idle (TM 5-3805-291-10).
4.
Raise empty bucket to 11.8 in. (30.0 cm) (TM 5-3805-291-10).
5.
Steer machine to left steering stop.
N OT E
Steering time for a full turn from stop to stop at high idle should not be more than 2.9 0.5 seconds.
6.
Record time it takes to steer machine to right steering stop.
7.
Record time it takes to steer machine to left steering stop.
8.
Steer machine straight ahead.
9.
Run engine at low idle (TM 5-3805-291-10).
10.
Steer machine to left steering stop.
N OT E
Steering time for a full turn from stop to stop at low idle should not be more than 4.9 0.5 seconds.
If times are not within specification, adjust steering control valve.
11.
Record time it takes to steer machine to right steering stop.
12.
Record time it takes to steer machine to left steering stop.
13.
Engage parking brake (TM 5-3805-291-10).
14.
Repeat steps 3 thru 12 with parking brake engaged.
STEERING CONTROL VALVE ADJUSTMENT
0016 00
N OT E
If both steering times are too slow, diameter of flow control orifice (16) is too small.
1.
Remove four bolts (17) and end cover (18) from steering control valve assembly (19).
N OT E
Add flow balance shims to steering control valve assembly to decrease steering time for right turn.
This causes the machine to steer to the right more quickly.
Steering time for left turn will increase.
This causes the machine to steer to the left more slowly.
If you remove shim, the result will be the opposite.
Use enough shims so steering times are nearly identical.
