72A3930 Tooth is a heavy‑duty cast digging tooth installed on LiuGong wheel loader bucket. As the front‑line working component, it directly contacts rock, ore and compacted soil during excavation and loading operations. It bears high impact and abrasive force, improves bucket penetration and protects the bucket base from rapid wear.
Working under severe site conditions such as quarries and aggregate yards, bucket teeth continuously suffer striking and friction. Long‑time operation will cause serious material loss, tip breakage, crack or mounting hole deformation. Damaged bucket tooth reduces digging efficiency, increases load on bucket base and accelerates wear of adjacent components, resulting in extra maintenance cost and unexpected machine downtime.

Installation Guide
Clean bucket mounting seat thoroughly, clear rock debris, rust and residual sundries before fitting.
Inspect new bucket tooth for casting crack, chipping and hole deformation, reject any damaged piece.
Align bucket tooth with bucket base seat precisely, do not force misaligned hammering installation.
Install matched locking accessories in place according to structure requirement, confirm reliable locking.
After installation, shake the assembly manually to confirm no loose movement, conduct short trial digging test.
Maintenance Tips
Inspect bucket tooth and locking accessories during each 500‑hour service interval, watch for excessive wear, crack and locking part loosening caused by impact vibration.
Check locking structure frequently under heavy‑load digging conditions, replace failed locking parts in time.
Replace bucket tooth promptly once crack or substantial material loss occurs, do not keep operating with severely damaged teeth.
While replacing bucket tooth, inspect bucket base seat for deformation and wear, repair relevant positions if necessary.
