143. BUCKET ROLLBACK CYLINDER DRIFTS.
NOTE
Steps 1 and 2 are the same for both bucket rollback 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 4-574, 4-576).
If hydraulic lines are not loose or damaged, go to step 2.
Step 2. Check for damaged bucket rollback cylinder packing as follows:
a. Start engine. Place bucket in full rollback position.
b. Stop engine.
NOTE
Use threaded plugs in hoses in steps c and i. Failure to do so will result in spilled
hydraulic oil.
c. Support bucket in full rollback position. Disconnect hose (1) from rod
end of each bucket rollback cylinder (2) and install threaded plugs.
d. Start and run engine at idle.
