WARN I N G
If machine is articulated, releasing system pressure on the articulation circuit will cause
the machine to move. Ensure that personnel are clear of machine prior to releasing
pressure on the articulation circuit. Failure to follow this warning may result in injury or
death to personnel.
1. Shut off machine (TM 5-3805-293-10).
2. Slowly turn articulation lock valves (Figure 20, Item 4) three complete turns. Allow pressure to release.
3. Disconnect two lines (Figure 20, Item 2) and remove O-rings (Figure 20, Item 3) from manifold (Figure 20,
Item 1). Discard O-rings.
4. Remove articulation lock valves (Figure 20, Item 4) and O-rings (Figure 20, Item 5) from manifold (Figure 20,
Item 1). Discard O-rings.
5. Install new O-rings (Figure 20, Item 5) on articulation lock valves (Figure 20, Item 4). Install articulation lock
valves on manifold (Figure 20, Item 1). Torque to 59 11 lb-ft (80 15 Nm).
6. Install two new O-rings (Figure 20, Item 3) and connect lines (Figure 20, Item 2) to manifold (Figure 20,
