Replace Digging Chain

Visually check digging chains for wear on teeth
(1), rollers, and sidebars (2). Check pins (3) and
bushing wear by measuring distance between
chain pins and comparing it with a new chain.

To remove chain:

1. Fasten and adjust seat belt.

2. Start tractor. See page 74 for proper start-up

procedures.

3. Move attachment direction/speed control until digging chain connector pin is on top of boom.

4. Lower boom to ground.

5. Engage parking brake and verify parking brake indicator is on.

6. Turn ignition switch to STOP.

7. Secure chain by clamping links on either side

of connector pin with chain jaws. Squeeze
jaws to reduce pressure on connector pin.

IMPORTANT:

Replace sprockets when a new

chain is installed.
