How do I confirm excavator bucket pin size before ordering a bucket or attachment?
Short Answer
Confirm excavator bucket pin size by measuring the actual pin diameter, pin center distance, ear width, and bushing style on the machine instead of trusting a generic chart alone. JIAJUE uses machine photos, old bucket measurements, and fitment drawings together because similar tonnage classes can still use different pin diameters or spacing between brands and serial ranges.
What To Check
- Send photos of the attachment ear area, old bucket or coupler, pins, bushings, and the machine model and serial plate.
- Measure pin diameter, center-to-center spacing, inside ear width, boss width, and whether the setup is pin-on, quick coupler, or shim-bushing style.
- Confirm whether you are matching an original bucket, another brand bucket, a thumb, or a coupler because each can change the required dimensions.
