Lever operating force
• With the engine turned off, place a push-pull scale on
the handle grip center or the pedal edge to measure
the force. Record the readings at the point at which the
lever/pedal reaches a full stroke.
Lever play
• Measure any discernible play at the tip of the lever or
pedal.
Backlash
• Measuring attitude: Completely retract the arm cylin-
der, and fully extend the bucket cylinder.
• Move the tips of the bucket teeth from side to side (left
and right), and measure the amount of play.
Slew bearing play
1. With the bucket in a no-load state, completely retract
the arm cylinder, fully extend the bucket cylinder,
move the dozer blade back, and make adjustments
so that the boom foot pin and bucket pin are at the
same height.
2. Attach a dial gauge to the bottom face of the slew
bearing’s outer race located near the front of the ex-
cavator, and set the dial gauge to 0.
3. Lower the boom, raise the crawler to the height, H,
and then read the dial gauge to get the measure-
ment.
