PROBLEM
9. External hydraulic fluid
leakage.
10. Hydraulic pump capacity
inadequate.
11. Lift cylinder rod bend when
lift cylinders extended.
1. Bucket cutting edge wear is
uneven side to side.
1. Bucket cutting edge wear
rate is excessive. (Wear rate
is even across full width of
bucket).
Note : Extensive use of bucket
on concrete or asphalt surfaces
will accelerate wear rate of
bucket cutting edge.

POSSIBLE CAUSE
Control valve O-rings defec-

tive.
Control valve spool or body

damaged or worn.
Cylinder rod packing set leak-

age.
Cold hydraulic fluid.

Engine R.P.M. too slow.

Low hydraulic fluid supply.

Hydraulic hose restriction.

Hydraulic pump defective.

Excessive shock load on lift

cylinders during transport.
Bucket is not level to ground.

Incorrect operational prac-

tices.
Excessive down pressure
placed on bucket when being
used on hard abrasive sur-
faces.
Bucket wear pads worn.

CORRECTION
Replace defective O-rings.

Replace control valve.

Check cylinders for leakage.

Repair as needed.
Allow hydraulic fluid to warm up to operating temperature.

Increase engine R.P.M.

Refer to Tractor Operator's Manual for service recommenda-

tions.
Check for evidence of restriction in hydraulic hoses.

Refer to Tractor Operator's manual for recommended ser-

vice procedures. Replace hydraulic pump if determined to
be defective.
Replace defective parts. Review and observe proper and

safe operational practices.
Check rear tire inflation and adjust to level bucket to ground.

Refer to operation-scraping section for correct operating pro-

cedures.
Utilize float position.
Replace wear pads.
