OEM 6Y3222 Long Bucket Tooth CAT J225 Style Replacement

1. Product Overview

The 6Y3222 Long Bucket Tooth is a premium aftermarket replacement ground engaging tool (GET) specifically engineered for the Caterpillar (CAT) J225 series. Featuring a standard long dirt profile, this tooth is the industry standard for 6 to 9-ton excavators, compact loaders, and backhoes. It is designed to deliver an optimal balance of penetration and wear life, making it the ideal choice for general-purpose digging, trenching, and loading in soil, clay, sand, and light gravel.

3. Key Features

• Self-Sharpening Design: The standard long profile is engineered to wear in a way that retains its sharpness, allowing your machine to penetrate the ground smoothly throughout the tooth’s lifespan.
• Exceptional Durability: Manufactured from high-grade alloy steel, these teeth provide excellent resistance to abrasion and impact, significantly reducing machinery downtime.
• Precision OEM Fit: Designed to match strict OEM specifications, ensuring zero rattling or loose fits when paired with standard J225 adapters.
• Versatility: The optimal wear-area-to-penetration ratio makes the 6Y3222 the most versatile option for mixed-condition job sites.

4. Manufacturing Process

Our 6Y3222 teeth are manufactured using the Lost Wax Investment Casting method rather than traditional sand casting. This advanced metallurgical process ensures:

1. Zero internal voids: Minimizing the risk of premature snapping under heavy loads.
2. Tighter tolerances: Ensuring a seamless lock with the adapter to prevent pin shearing.

Following casting, the teeth undergo a rigorous heat treatment process (quenching and tempering) to achieve a uniform core hardness of 47-52 HRC, providing the perfect balance between surface wear resistance and internal shock absorption.

5. Applications & Machine Compatibility

The 6Y3222 Long bucket tooth is widely used on 6-9 ton class machinery. It is a direct fit for a broad range of Caterpillar equipment, including but not limited to:

• Mini/Compact Excavators: 305.5E, 306, 307, 307B/C/D/E, 308D/E, E70B
• Backhoe Loaders: 416D, 420D, 430D, 446, 446B/D, 450E, 450F
• Track Loaders: 931C II, 933, 933C

6. Accessories: Pins, Retainers & Adapters

To securely mount the 6Y3222 tooth, specific side-mount fastening hardware is required. (Note: Fasteners are often sold separately unless bundled in a kit).

1. Retaining Pin: 6Y3228 (Dimensions: ~2.71″ length, steel construction)
2. Retainer/Lock Nut: 8E6259 (or equivalent 3G9609) (~0.53″ inner diameter)
3. Compatible Weld-on Adapter: 6Y3224 (1″ to 1-1/16″ lip thickness)

7. Common Industry FAQs

Q1: How do I measure my bucket tooth to ensure the 6Y3222 long bucket tooth is the right fit?
A: Measure the inner pocket height and width where the tooth slides over the adapter. The 6Y3222 pocket roughly measures 47mm x 58mm. Additionally, verify that the pinhole is on the side of the tooth, not the top.

Q2: What is the difference between a standard dirt tooth (6Y3222) and a tiger tooth?
A: A standard dirt tooth (like the 6Y3222) has a wider, flatter blade profile. It lasts longer due to a larger wear mass and leaves a cleaner trench floor. A tiger tooth has a sharp, pointed tip designed for maximum penetration in hard ground but wears out faster because it has less steel mass.

Q3: Are these teeth only compatible with CAT machines?
A: While engineered for the CAT J225 system, these teeth will fit any brand of excavator, skid steer, or backhoe (JCB, Bobcat, Kubota, Deere) provided the bucket has been welded with J225 series adapters.

Q4: How often should I replace my 6Y3222 teeth?
A: Replacement intervals depend entirely on the material you are digging. You should replace the teeth when the tip becomes rounded and blunt (reducing machine efficiency and burning excess fuel) or if the pocket housing becomes loose on the adapter.
