J. CHECK AND ADJUSTMENT

a . Hydraulic Cylinder Bore

1. Check the cylinder inside surface for scratches or

damage.

2. Using a cylinder gauge, measure cylinder I.D.

3. If the measured exceeds the allowable limits, re-

place the hydraulic cylinder block.

b. Clearance Relationship Between Hydraulic

Arm Shaft and Bush

1. Using a O.D. micrometer, measure the hydraulic

arm O.D.

2. Using a I.D. micrometer, measure the bush I.D. and

then calculate the clearance.

3. If the calculated clearance exceeds the allowable

limits, replace the bush.
