Replacing bucket teeth is a common maintenance task for excavators, loaders, and other heavy equipment. Proper replacement ensures operational efficiency and safety. Below is a step-by-step guide and key considerations.

1. Preparation
① Safety First
 Park the machine on level ground, lower the bucket, and engage safety locks.
 Wear gloves, safety glasses, and steel-toe boots to prevent injuries.

② Tools Required
Depending on the tooth retention system, prepare:
Bolt-on teeth: Wrench, impact gun (heat may be needed if bolts are rusted).
Pin-on teeth: Hammer, punch, pin puller, or hydraulic press.

③ Select the Correct Replacement Tooth
 Match the tooth model with the old one (check the equipment manual or measure dimensions).

2. Removing the Old Tooth
① Bolt-On Teeth
Apply penetrating oil to rusted bolts, then use an impact wrench.
If bolts are broken, drill them out carefully.

② Pin-On Teeth
 Remove any retaining clips or locks
Use a punch and hammer to drive out the pin (heat may help if corroded).

3. Installing the New Tooth
① Clean & Inspect
Remove dirt, rust, or debris from the adapter (shank).
 Ensure the new tooth fits snugly without gaps

② Secure the Tooth

Bolt-on: Apply anti-seize lubricant, tighten bolts in a cross pattern(follow torque specs).
Pin-on: Insert the pin, then install new retaining clips or locks.

4. Key Considerations
Replace in Pairs – Avoid uneven wear by changing matching teeth on both sides.
Check Tightness – Inspect bolts/pins after the first few hours of operation.
Stop if Loose – If a tooth wobbles, immediately stop and re-tighten.

5. Extending Tooth Life
Choose the right tooth type:
Rock teeth (hardened alloy) for abrasive ground.
Standard teeth for loose soil.
Avoid side-loading– Dig straight to reduce stress.
Rotate teeth – Swap left/right teeth to balance wear.
