BUCKET REPLACEMENT
Removal
1. Prepare the machine for service. See “Maintenance
2. Place the bucket (3) on level ground and block the
bucket to prevent movement.
NOTE:
Before removing the pins, slowly lower the
bucket to a level where it just touches the
ground. If too much down-force is used,
resistance on the pins could increase, causing
difficulty during removal.
3. Remove the fasteners on the plate that retains the arm
pin (2) and link pin (4).
4. Remove the arm pin and link pin, and then remove the
bucket.
NOTE:
Clean the pins of mud and sand after removal.
Inspect seals and bushings. Replace as necessary.
CAUTION!
• Keep fingers and other body parts away from pinch points to prevent crushing injuries
while removing or installing the bucket. Never put your finger into the pin bore during
alignment.
• Secure bucket after removal and before servicing.
• Bucket pins may be ejected with extreme force when removed forcefully. Do not allow
anyone to stand in front of the pins during removal.
• Never stand or place your feet or other body part under the bucket when removing bucket
pins.
Failure to follow these cautions could result in injury
