PROBLEM

Show/hide table

The existing 278-1170 Hose for the stick cylinder head end can be damaged due to interference with the 142-1072 Hose for the boom cylinder rod end on certain 416E Backhoe Loaders. Improper orientation of the 278-1170 Hose Assembly causes the problem, which could result in a failed hose.

Rework Procedure

Show/hide table

1) The 278-1170 Hose Assembly for the stick cylinder head end may be routed incorrectly on some 416E Backhoe Loaders due to the elbow being oriented incorrectly. The correct orientation of the hose is shown in Image 1.1.1.

Image1.1.1

2) If the hose assembly is not routed as shown, disconnect the elbow fitting and loosen the straight fitting on the other end of the hose. The hose clamps may also need to be loosened to re-position the hose.

Note: If the 278-1170 Hose Assembly is damaged, replace the hose assembly. This hose is buildable.

3) Orient the hose elbow as shown and re-tighten the elbow. Make sure the hose is not twisted and then re-tighten the straight fitting at the end on the hose.
