Alloy Steel 132-4720 Unitooth Excavator Bucket Teeth

1. Product Overview

The Caterpillar-Style132-4720 Unitooth is a bolt-on bucket tooth designed specifically for compact machinery. Engineered to maximize the digging efficiency of skid steers and mini excavators, is a highly reliable and cost-effective aftermarket replacement, ensuring your equipment stays on the job site and out of the repair shop.

2. Detailed Specifications

3. Key Features

• Optimized Curved Profile: The swept-back, curved design reduces digging resistance and allows for smoother, more efficient penetration into dense dirt, gravel, and clay.
• Exceptional Durability: Crafted from low-carbon alloy steel, these teeth are built to absorb high-impact shocks without snapping, extending their operational lifespan.
• Direct-Fit Replacement: Designed to seamlessly replace OEM Caterpillar parts, ensuring a hassle-free installation process with standard 2.38-inch center-to-center bolt spacing.
• Cost-Effective Aftermarket Value: Delivers OEM-level performance and wear resistance at a fraction of the cost, lowering your overall operating expenses.

4. Manufacturing Process

The 132-4720 Unitooth is manufactured using an advanced casting process. Molten low-carbon alloy steel is poured into precise molds to form the unitooth’s distinct curved shape.
Following the casting, the teeth undergo a rigorous heat-treatment and tempering process. This critical step aligns the granular structure of the steel, providing a hardened outer layer for maximum abrasion resistance while maintaining a tough, ductile core to prevent the tooth from shattering under heavy impacts.

5. Applications

This unitooth is the ideal ground-engaging tool for lightweight to medium-duty earthmoving tasks. It is perfectly suited for:

• Skid Steer Loaders: Enhancing standard dirt buckets for grading, site prep, and material handling.
• Mini Excavators: Improving trenching speed and bucket penetration in compact spaces.
• Compact Track Loaders & Backhoes: Upgrading front-end loader buckets for general construction and landscaping applications.

6. Accessories & Hardware Kits

To ensure maximum uptime, we highly recommend purchasing your 132-4720 bucket teeth alongside matching hardware.

1. Complete Hardware Kits: Proper installation requires heavy-duty plow bolts, washers, and hex nuts. Ensure you have the exact bolt size required for your specific bucket lip thickness (commonly 5/8-inch bolts).
2. Cost-Effective Multi-Packs: Because bucket teeth wear evenly, it is standard practice to replace the entire set at once. Purchasing a 4-pack, 5-pack, or 8-pack is the most economical way to restore your bucket to peak performance while saving on unit costs and shipping.

7. Important Considerations for Buyers

Before purchasing, verify the following details to guarantee a perfect fit for your machine:

1. Measure Your Bolt Spacing: Use a tape measure to verify that your current bucket’s bolt holes are exactly 2.38 inches apart from the center of one hole to the center of the next.
2. Verify Your Hardware: The unitooth does not always ship with hardware. Check your bucket’s lip thickness to ensure you order bolts of the correct length and diameter.
3. Confirm Machine Compatibility: While this is a universal CAT-style tooth, verify that your skid steer or mini excavator bucket is equipped with a bolt-on edge designed to accept standard unitooth profiles.

8. Frequently Asked Questions (FAQs)

Q1: Will the 132-4720 fit my non-Caterpillar machine?
Yes. “Caterpillar-style” refers to the universal shape and mounting pattern of the tooth. As long as your bucket has a bolt-on lip with a 2.38-inch center-to-center hole spacing, these teeth will fit most major brands, including Bobcat, John Deere, Kubota, and Case.

Q2: Why should I choose low-carbon alloy steel?
Low-carbon alloy steel offers the perfect balance of hardness and flexibility. High-carbon steel is very hard but brittle, making it prone to snapping on rocks. Low-carbon alloy flexes slightly under extreme pressure, preventing breakage while still offering excellent wear resistance against dirt and gravel.

Q3: Do I need to weld these on?
No. The 132-4720 is a bolt-on unitooth. This allows for rapid, on-site replacements using standard hand tools, eliminating the need for a welder or cutting torch.

Q4: How often should I replace my bucket teeth?
Teeth should be replaced when the curved tip becomes blunt or flat, or if you notice your machine struggling to penetrate the ground. Running a machine with worn-out teeth increases fuel consumption and causes unnecessary wear on the bucket lip and the machine’s hydraulic system.
