Steps for replacing the bucket tooth of a loader

I. Safety Preparations

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

2. Wear protective equipment such as goggles and gloves, and clear away debris in the work area.

2. Disassemble the old bucket teeth

Identify the installation type

Direct installation type (vertical pin shaft): Use the short tooth of the pin breaker to align with the tooth pin, hammer until it becomes loose, and then replace the long tooth to completely knock out the pin shaft.

Horizontal installation type (parallel pin shaft): A long rod tool is needed to strike from the side to avoid jamming.

2. After removing the old bucket teeth, clean the residual sand and rust on the tooth seat.

Iii. Component Inspection and Cleaning

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

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

3. 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

Insert the retaining ring into the side groove of the tooth seat, with the letter marking of the bucket teeth facing upwards and aligning 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 it until it is fully inserted (for horizontal installation, keep the pin shaft parallel to the tooth surface).

Test stability: No wobbling when kicking, and the end of the pin shaft is flush with the tooth seat.

V. Acceptance and Commissioning

Start the equipment to lift and lower the bucket 3 to 5 times without load, and observe that there is no displacement or abnormal noise from the bucket teeth.

2. Suggestions for working condition adaptation:

Sandy soil conditions: Prioritize flat teeth (to maintain sharpness);

Hard rock working conditions: Select RC type rock teeth (thickened for impact resistance).
