Conduct Inspection for Bucket Teeth

Date:21-12-2016

Although Bucket Teeth is made to last, it does wear and must eventually be replaced. As with most systems of your machine, bucket tooth requires regular inspections to identify wear and cracks. These inspections provide an opportunity to make repairs prior to structural damage or failure.

After the results of the inspection have been assessed, maintenance, reconditioning, or replacement may be required. If the inspection indicates that reversing, rotating or replacing tips, adapters, corner bits, edges, and wear plates is required, this should be done promptly. After all, good bucket tooth maintenance can extend its service life and save owner’s money in the long run.

As part of your inspection, watch for the following:

1. Excessive wear, bending or bell mouthing in corner areas.

2. Cracked or worn-through areas at weld joints.

3. Badly bent or broken-through corner gussets.

4. Cracks along welds or plates inside and underside of buckets.

5. Missing tips, retainers and worn adapters, especially adapter straps and noses.

6. Check the adapter weld for cracks.

7. Check for missing or loose bolts and inspect the base edge for wear or scalloping.

8. For side pinned tips and adapters, watch the retainer slot in the pin and retainer assembly. If the slot becomes too wide, there will be a loss in retention which can affect performance.

9. Remember, loose or missing bolts can also cause a failure.

Even one or two missing tips reduce digging ability and increase the speed of base edge wear. When tips are missing, the adapters bear the full brunt and wear faster. Therefore, it is advisable to run cutting edges and tips to their full service life, but not beyond. Bucket tips seldom wear evenly, and the ones near the bucket corners usually wear the fastest. Rotate the worn outer tips to the center and vice versa. When rotating, reverse tips to further wear life.

Check and replace missing or damaged hardware. Tighten any loose hardware. Prolonged operation with loose hardware will cause bolt holes to elongate. Inspect the surface where the retaining nut will be positioned. This surface should be solid, smooth, and flat to support the nut. If it is not, it will be impossible to keep the hardware tight.
