Short answer
An excavator bucket inspection checklist records one bucket's condition: pins and bushes, teeth and adapters, cutting edge, ear plates, welds and quick coupler engagement, ending in a keep, watch or retire decision. A competent person completes it. Regulation 213 of the model WHS Regulations requires inspection following the manufacturer's recommendations, or without them a competent person's, or annually if neither is practicable; wear limits come from the OEM manual.
Checked against Model WHS Regulations as at 5 December 2025 (cited within as the Work Health and Safety Regulations 2011) on by the MapTrack templates team. How we check templates
Key takeaways
- The MapTrack excavator bucket inspection checklist contains 29 checks across 5 sections. Sections covered: Bucket identification & coupler, Pin & bush measurement, Teeth & ground engaging tools, Structural wear & cracking, Disposition & records.
- Wear limits for teeth, pins, bushes and cutting edges come from the OEM manual; record each measurement and the limit applied.
- Check quick coupler latch engagement and the secondary lock at every inspection, because an attachment drop is a high-consequence failure.
- Inspect the bucket out of cycle after an impact, a dropped attachment or a coupler fault, before it returns to service.
- AS 20474.1:2025 and AS 20474.5:2025 cover machine and attachment design safety, not in-service wear criteria.
- Track inspections against the bucket's own ID so its history follows it between carrier machines.

What is an excavator bucket inspection checklist?
An excavator bucket inspection checklist is the attachment-level structural and wear assessment used by a competent person to decide whether a hydraulic excavator bucket stays in service, goes on a watch list, or is retired and replaced. It applies to general-purpose (GP) buckets, heavy-duty (HD) rock buckets, tilt buckets and any bucket carried on a hydraulic or pin-grab quick coupler across mobile and tracked excavators from 5 tonne mini-excavators up to 200 tonne class production machines. Unlike an excavator pre-start that runs across the whole carrier, or a 250 hour service that focuses on lubricants and filters, this checklist concentrates on the bucket itself. The scope covers identification (size, type, GET pattern, OEM or aftermarket build, fitment to quick coupler), bucket pin and bushing wear at both lift-arm and tilt-link positions with the 10 percent diameter reduction discard rule, bucket teeth condition against the 50 percent wear discard threshold, side cutter and bolt-on adapter retention, cutting edge wear measurement, ear plate cracks, side bracket cracks, bucket back and rib wear, quick coupler hook latch engagement and the magnetic particle inspection (MPI) check on suspect weld zones.
AS 20474.1:2025 (Earth-moving machinery - Safety) sets safety requirements for how earth-moving machines and their attachments are designed and built, and ASME B30.20 (Below-the-hook lifting devices) applies where the bucket is used for lifting through a shackle point. ISO 6165 gives the underlying earth-moving terminology that OEM documentation works to, and the WHS Regulations 2011 Chapter 5 make attachment condition part of the PCBU plant maintenance duty. The Safe Work Australia Code of Practice on managing the risks of plant in the workplace (November 2024) is the practical guide most supervisors use to scope this inspection. Where bucket teeth are worn beyond 50 percent or pins show more than 10 percent diameter reduction, the inspector either retires the attachment on the spot or sets a shorter inspection interval until rebuild. A digital record in MapTrack ties each inspection to the bucket serial, the carrier excavator, the install date and the operating hours so retirement decisions remain defensible at audit.

Benefits of using this excavator bucket inspection checklist
- Attachment-level accountability: Each bucket decision is signed against the competent inspector who measured pins and teeth, not lost inside a generic excavator signature
- Wear and discard record: The checklist records each wear measurement and the discard threshold applied, so SafeWork audits and OEM warranty claims are straightforward
- Per-attachment traceability: GP, HD and tilt buckets are inspected individually with their own ID, install date and operating hour count against the carrier
- Tooth and edge wear visibility: The 50 percent tooth wear and 10 percent pin reduction triggers are captured in measurement so retirement is data-driven, not a guess at a glance
- Coupler safety assurance: Quick coupler hook latch engagement and secondary lock function are signed off, preventing the uncommanded attachment drop incidents that have killed Australian operators
- Weld defect interception: Documented MPI checks on ear plates, side brackets and bucket backs intercept fatigue cracks before they propagate into structural failure under load
- Lifecycle records: Every bucket rebuild, tooth replacement, inspection and discard sits against the attachment for the full life of the asset

What to include in an excavator bucket inspection checklist
This excavator bucket inspection checklist covers 13 key areas:
- Bucket identification: type (GP/HD/tilt), capacity, GET pattern, OEM or aftermarket build, serial number, carrier excavator ID and operating hours since install
- Quick coupler interface: hook latch engagement on both front and rear pins, secondary lock pin position, hydraulic coupler pressure hold test with no oil seepage at disconnect
- Bucket pin and bushing wear: dial-indicator measurement at lift-arm pin, tilt-link pin and bucket-link pin against OEM clearance, 10 percent diameter reduction discard rule applied
- Bucket teeth condition: tooth height measurement at each tooth against new tooth dimension, 50 percent wear discard threshold marked, retainer pin and rubber condition checked
- Side cutters and bolt-on adapters: bolt tension on every fastener, side cutter wear measurement, adapter weld inspection and replacement parts on order if approaching discard
- Cutting edge wear: cutting edge thickness measurement at three points across the lip, weld-on or bolt-on edge fastener condition, undercut depth on the leading face
- Ear plate inspection: visual and MPI inspection of ear plates for fatigue cracks at the lift-arm pin, tilt-link pin and structural welds, any indication photographed for follow-up
- Side bracket inspection: visual and MPI inspection of side brackets for fatigue cracks at the carrier attachment points and along the longitudinal welds
- Bucket back and rib wear: rear bucket wear measurement against the original profile, rib wear and rib weld condition, any wear-through points marked for re-plating
- Quick coupler condition: hook plate latch wear, retention pin condition, hydraulic line and electrical loom condition through the coupler interface
- Weld inspection (MPI on suspect zones): magnetic particle inspection on any suspect weld indication, fluorescent or visible-dye method, full report attached to the inspection record
- End-of-life decision: keep in service, watch list with shorter inspection interval, partial rebuild (teeth and edge), or full retirement and replacement
- Inspector sign-off: name, competent-person status, trade certificate number, date and next scheduled inspection
How to use this excavator bucket inspection checklist
- 1. Plan the inspection and isolate the carrier: pull the bucket history file including ID, install date, operating hours and previous wear measurements, position the carrier on level ground with the bucket flat on the deck, lock out the ignition and key in pocket, allow the bucket to cool before measurement
- 2. Identify the bucket and confirm fitment: confirm bucket type (GP, HD, tilt), capacity, GET pattern, OEM or aftermarket build, serial number and carrier excavator ID, verify quick coupler compatibility against the manufacturer compliance plate
- 3. Inspect the quick coupler interface: function-test hook latch engagement on both front and rear pins, verify secondary lock pin position, complete the hydraulic coupler pressure hold test and confirm no oil seepage at disconnect
- 4. Measure bucket pins and bushings: attach the dial indicator to each pin position (lift-arm, tilt-link, bucket-link), lever the linkage against the indicator and record the measured clearance against the OEM specification, apply the 10 percent diameter reduction discard rule
- 5. Measure bucket teeth and edges: measure each tooth height against the new tooth dimension, mark any tooth past the 50 percent wear threshold for replacement, check retainer pin and rubber condition, measure the cutting edge thickness at three points across the lip
- 6. Inspect side cutters, bolt-on adapters and ribs: check every fastener for correct tension, measure side cutter wear, inspect adapter welds for cracking, measure rear bucket and rib wear against the original profile
- 7. Complete weld visuals and MPI on suspect zones: walk ear plates, side brackets, bucket back, ribs and structural welds for fatigue cracks, photograph any suspect indication and complete magnetic particle inspection on the marked zones
- 8. Make the end-of-life decision and record: mark the bucket as fit for service, watch list (with a shorter inspection interval), partial rebuild (teeth and edge), or retire and replace now, photograph any discard-criteria finding, sign the record and attach to the asset in MapTrack

Regulation 213 of the WHS Regulations 2011 requires the bucket to be inspected by a competent person, following any recommendations of the manufacturer, so the OEM service manual is the starting point for the cadence the bucket inspector should follow. The operator runs a visual pre-start bucket check each shift, looking for obvious tooth loss, cracked welds and quick coupler engagement at the visible interface. A weekly visual inspection by a trained technician covers more of the bucket under controlled conditions. A monthly inspection by a competent person covers tooth and pin wear measurement, cutting edge thickness and structural weld visual. A 6-monthly major inspection sits inside the carrier excavator monthly cadence and goes deeper, including MPI on ear plates, side brackets and bucket back welds where the bucket is on heavy production duty. Any impact event, dropped attachment, hydraulic coupler failure or near-miss triggers an out-of-cycle inspection of the bucket before it returns to service. In MapTrack the bucket inspection schedule sits against the bucket ID rather than the carrier excavator, so an attachment swap or quick coupler change resets the cadence automatically.
