STEERING TIME CHECK - CONTINUED
d.
Pump may have excessive wear. If so, replace pump (WP 0182 00).
e.
If cycle time is slow for only one steering circuit, circuit with slow cycle time should be tested for one of these
conditions:
(1)
Low relief valve setting.
(2)
Leak in circuit.
(3)
Control spool that is not shifting fully.
f.
If steering times are consistently slow in one direction, replace secondary steering relief valve (WP 0104 00).
STEERING FORCE CHECK
0016 00
1.
Remove horn button from center of steering wheel. Disconnect wire from horn button. Push wire down shaft (WP 0098
00).
2.
Place 0.7 in. (18 mm) socket on nut in center of steering wheel. Position torque wrench on nut. Use socket extension to
avoid interference with steering wheel.
3.
Use torque wrench to turn steering wheel very slowly. Force needed to turn steering wheel should be 38 2 lb-in.
(4.29 0.23 Nm).
4.
Start engine (TM 5-3805-290-10). Run engine at low idle.
5.
Use torque wrench to turn steering wheel very slowly. Force needed to turn steering wheel should be 23 2 lb-in.
(2.59 0.23 Nm).
6.
Pull wire from shaft. Connect wire to horn button.
7.
Install horn button on steering wheel (WP 0098 00).

STEERING WHEEL SLIP CHECK
1.
Slightly raise work tool off ground (TM 5-3805-290-10).
2.
Release service brakes (TM 5-3805-290-10).
3.
Run engine at low idle (TM 5-3805-290-10).
4.
Ensure machine is in straight-ahead position.
5.
Slowly turn steering wheel through one revolution so there is minimum articulation.
6.
Slowly turn steering wheel in opposite direction so there is minimum articulation.
7.
Slowly turn steering wheel through one revolution to left three times. Record time needed for each revolution of steering
wheel.
8.
Slowly turn steering wheel through one revolution to right three times. Record time needed for each revolution of steer-
ing wheel.
9.
Add recorded times for three left turns together.
10.
Add recorded times for three right turns together.
a.
If total for three left turns and total for three right turns are 60 seconds or more, then slip is acceptable.
b.
If each total is greater than 60 seconds, problem is in steering system. Refer to Steering System Troubleshooting in
