Corrective Action

BACKHOE (SEE) (CONT)

NOTE

Use threaded plug in hose. Failure to do so will result in spilled hydraulic oil.

b. Stop engine. Disconnect hose (4) from closed end of swing cylinder (5)

and install threaded plug.

Start and run engine at 2000 rpm.

NOTE

During step d, there may be a small amount of hydraulic oil leaking, either drops or a

small stream the diameter of a pencil lead. This is normal. Use drip pan to catch oil.

d. Move swing control lever to move backhoe (to left for left swing cylinder

or to right for right swing cylinder). Hold lever in position and check for

leaks from fitting (6) at closed end of swing cylinder.

If there is excessive leakage from fitting, replace swing cylinder

(page 4-660).

If there is not excessive leakage from fitting, notify direct

support maintenance.

NOTE

Steps 1 and 2 are the same for both stabilizer cylinders.

Step 1. Check for loose and damaged hydraulic lines.

If hydraulic lines are loose or damaged, tighten loose

connections or replace hydraulic lines (pages 4-600, 4-602,

4-604).

If hydraulic lines are not loose or damaged, go to step 2.
