PERFORMANCE CRITERIA
2D0AX002
Natural travel drop
• Engine:
Stopped
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Inclination angle:
15°
• Measuring attitude: Fully extend the boom, arm, and
bucket cylinders. Completely retract the dozer blade
cylinder.
• Leave the excavator parked at an angle for 5 minutes
and then measure the amount of natural drop.
Slew time
• Engine:
Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: With the bucket in a no-load state,
completely retract the arm cylinders, and then fully ex-
tend the bucket cylinder and make adjustments so that
the boom foot pin and bucket pin are at the same
height.
• Set the upper structure in motion, wait 1 rotation, and
then measure the time required for the next 2 rotations.
Overrun when slewing stops
• Engine:
Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: Same as that for measuring slew
time
• Draw matching marks on the outer race of the slew
bearing and the lower frame at points rotated exactly
180° from the starting point. With the hoe attachment
in a no-load state, slew another 180 degrees, at which
point the operation lever should return back to neutral.
Measure the difference between the position marks
and the point at which the hoe attachment was
stopped.
Natural slew drop
• Engine:
Stopped
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Inclination angle:
15°
• Measuring attitude: Same as that for measuring slew
time
• Rotate the upper structure so that it is directly abeam
of the grade. Next, draw positional marks on the outer
race of the slew bearing and on the lower frame. Mea-
sure the amount of distance that opens up between
the marks after 5 minutes have passed.
