Designed to deliver stable, wear-resistant performance under varying loads, reducing vibrations and potential bearing issues. Quality control is highlighted to reassure stable operation.
- Best for heavy-duty use where bucket pin fit is critical.
- Choose this if you need reliable rotation with reduced wear.
Caution: Ensure exact dimensions (ID/OD/L) match your equipment to avoid improper fitment.
Innconee 8 Packs 45MM Bucket Pin Shim
Brand: Innconee. Built to endure with a resin construction, sized for outer diameter ~100 mm, inner diameter 45 mm, and 3 mm thickness. Highlights include even load distribution and resistance to cracking, oil stains, and aging. Aimed at sealing, cushioning, and longer lubrication cycles.
- Best for shimming and load distribution to extend pin life.
Caution: Material is resin; consider chemical compatibility with your environment and oils.
Excavator Bucket Bushing (45X55X40MM)
Brand: PUREYEMAN. This variant provides a smaller length (L 40 mm) while maintaining the same ID/OD. It suits lighter loads and tight spaces where a shorter bushing is required for proper clearance and smooth operation.
- Best for compact configurations or lighter duty cycles.
Caution: Confirm the correct L dimension for your specific bucket and pin assembly to avoid contact or binding.
4pcs 140-5168 265-8715 Bucket Pin Bushing Kit
Brand: madoext. Replacement part numbers indicate CAT compatibility for excavator models including 304, 304CR, 305CR, 303.5C, 303C CR. Highlights long-lasting durability and a wear-resistant finish designed to absorb shocks and reduce abrasion at bucket pivot points.
- Best for CAT models listed in compatibility notes.
Caution: Data relies on part-number compatibility; verify exact model applicability before purchase.
4 PCS Bucket Ears 40 MM Bushings
Brand: Generic. Suitable for various small excavators, these weld-in ears bushings provide a straightforward solution for common bucket wear points and are designed for easy integration with existing hardware.
- Best for small or older compact machines with standard 40 mm ears.
Caution: Generic labeling means verify exact dimensions and fitment with your machine’s ears.
Tiger Tool Pin And Bushing Adapter 15060
Brand: Tiger Tool. Designed to work with the Pin & Bushing Starter Kit and facilitate pin and bushing removal or installation across heavy-duty trucks and equipment. Useful for technicians performing maintenance without removing suspension in many cases.

Buying Guide: Key Considerations For Excavator Pins And Bushings
What to check before buying: dimensions (ID, OD, length or thickness), compatibility with your machine brand and model, material and hardness, installation ease, and the expected service life under your operating conditions.
- Match dimensions precisely to avoid loose fit or binding.
- Consider universal vs. brand-specific kits depending on your fleet diversity.
- Evaluate wear resistance and the ability to absorb shocks in bucket pivot points.
- Assess installation complexity and whether additional tools or adapters are needed.
- Account for maintenance intervals and downtime when selecting shim kits or bushings.
Frequently Asked Questions
- What is the difference between a bucket pin bushing and a shim?
- How do I measure for the correct bushing size?
- Are universal bushings suitable for all brands?
- Can these parts affect machine safety?
- Should I replace bushings and pins at the same time?
Pin bushings replace worn contact surfaces around the bucket pin, while shims adjust clearance and load distribution to reduce play and wear.
Measure the pin’s inner diameter (ID), the hole’s outer diameter (OD), and the required shim thickness or bushing length to ensure a precise fit.
Universal kits cover many brands but may require trimming or extra adaptation for a perfect fit on some machines.
Yes. Properly sized and installed bushings and pins help maintain stable operation and reduce unexpected wear that could impact safety.
Replacing both together is common to ensure balanced wear and consistent performance, especially on heavily used equipment.
