Tutorial for replacing excavator bucket teeth

I. Preparatory Work

1. Safety Protection: Shut down the machine and turn off the engine, cut off the power supply, pull the safety lock rod to the "locked" position, and place a pad at the bottom of the bucket to ensure it is level and stable.

Wear goggles and anti-crush gloves, and clear away debris in the work area.

2. Tool preparation

Direct-mounted bucket teeth: Bucket teeth wrench (pin breaker), hammer;

Horizontal bucket teeth: Extended striking rod, special retaining ring pliers.

2. Disassemble the old bucket teeth

Identify the installation type

Direct-mounted type (pin shaft vertical):

Align the short teeth of the pin breaker with the pin and hammer it to loosen it to half position.

Replace the long teeth and continue to strike until the pin shaft completely falls off.

Horizontal installation type (parallel pins):

Use a long-pole tool to strike the pin shaft from the side and remove it in sequence to avoid jamming.

2. Remove the residual sand and rust from the tooth seat and check whether the pin holes are deformed.

Iii. Component Inspection and Cleaning

1. Tooth seat assessment: If the wear exceeds 10%, it should be replaced simultaneously to prevent the new teeth from breaking due to uneven force.

2. Pin shafts and retaining rings: Deformed or worn lock pins must be replaced (worn parts are prone to fall off).

3. Thoroughly clean the installation surface of the tooth seat, pin holes and slots with a wire brush to ensure there is no welding slag or foreign objects.

Four. Install new bucket teeth

1. Assemble components

The retaining ring is embedded in the side groove of the tooth seat, and the letter marking of the bucket teeth is facing outward and aligned with the tooth seat.

The direct-mounted type needs to be pre-installed with anti-drop lock plates.

2. Fixed pin shaft

Manually insert the pin shaft to 1/3 depth and hammer until it is fully inserted (for horizontal installation, keep the pin shaft parallel to the tooth surface).

Acceptance criteria: The foot kick should not shake, and the end of the pin shaft should be flush with the tooth seat.

V. Debugging and Maintenance Suggestions

Lift and lower the bucket 3 to 5 times without load to observe if there is no displacement or abnormal noise from the bucket teeth.

Vi. Key Safety Regulations

Prohibited behavior:

Body parts must not be placed under the bucket, and fingers must not be inserted into the pin holes.

It is strictly prohibited to operate directly without locking the device. 9

2. Welding repair limitations: Only the tooth seat plate is allowed to be repaired (preheated to 100°C+J507 electrode), and direct welding of the bucket teeth is prohibited (prone to secondary fracture). Operation mnemonic: 1. Stop (machine), 2. Clear (base), 3. Align holes (pin shafts), 4. Check stability (kick test). Standardized operation can increase efficiency by 50% and reduce the failure rate by 35%.
