9N4252 CAT J250 Style Long Bucket Tooth Heavy Duty Excavator Parts

1. 9N4252 Long Bucket Tooth fit CAT J250 Series

The 9N4252 Heavy-Duty Long Bucket Tooth is Specifically engineered to fit the industry-standard Caterpillar J250 series, this long-style tooth provides an optimal balance of strength, penetration, and wear life.

2. Detailed Specifications

3. Key Features

• Enhanced Penetration: The long, streamlined profile reduces digging resistance, significantly improving cycle times and fuel efficiency.
• Heavy-Duty Durability: Engineered with extra wear material in critical areas to withstand highly abrasive conditions without prematurely losing its sharp profile.
• Self-Sharpening Design: The geometry of the tooth is designed to wear in a way that maintains a sharp digging edge throughout its lifespan.
• Universal J250 Fit: Manufactured to precise OEM specifications, ensuring a snug, rattle-free fit on all standard J250 adapters.

4. Applications

The 9N4252 Long Bucket Tooth is highly versatile and excels in general-purpose to heavy-duty digging environments. It is highly recommended for:

• Equipment: Compactors, Backhoe Loaders, and Mini Excavators.
• Ground Conditions: Dense dirt, clay, loose gravel, loam, and mixed topsoils.

5. Manufacturing Process

Our 9N4252 bucket teeth are manufactured using an advanced investment casting or sand casting process utilizing premium alloy steel.

1. Casting: The raw alloy is melted and poured into precise molds to guarantee exact pocket dimensions (66-70mm width / 53-57mm height) for a perfect fit.
2. Heat Treatment: Each tooth undergoes a rigorous quenching and tempering process. This maximizes core toughness (to prevent snapping under heavy impact) while ensuring extreme surface hardness (to resist abrasive wear).
3. Quality Control: Every batch is tested for impact resistance, hardness, and dimensional accuracy to ensure it meets strict heavy machinery standards.

6. Important Considerations for Buyers

1. Verify Fitment: Before purchasing, measure your current adapter or check your machine’s manual to ensure it uses the J250 series system. The pocket dimensions should closely align with your shank size.
2. Replace Hardware: Never reuse old pins or retainers. Worn hardware can lead to tooth loss during operation, potentially damaging the adapter or crusher machinery down the line. Always purchase new 9J2258 pins and 8E6259 retainers.
3. Match Tooth to Terrain: While the long style is excellent for general digging and penetration, extreme rock conditions might require a specialized rock chisel tooth instead.

7. Common Industry / Buyer FAQs

Q1: Will the 9N4252 fit my specific brand of backhoe?
A: The 9N4252 is determined by the bucket’s adapter (shank) series, not the machine brand. If your bucket is equipped with a CAT J250 series adapter (like the 6Y3254, 1U1254, or 1U0257), this tooth will fit perfectly, regardless of whether your machine is a Caterpillar, John Deere, Case, or Komatsu.

Q2: How do I install the 9N4252 bucket tooth?
A: The J250 series uses a side-pin system. Slide the tooth over the adapter, insert the 8E6259 retainer into the adapter’s recess, and drive the 9J2258 pin through the side of the tooth and adapter using a pin punch and hammer until it locks securely into the retainer.

Q3: How long will this bucket tooth last?
A: Lifespan varies heavily based on the material you are digging. In standard dirt and clay, the 9N4252 will offer hundreds of hours of service. Highly abrasive materials like silica sand or granite gravel will accelerate wear. Its heavy-duty alloy construction ensures it outlasts standard-duty cast teeth.

Q4: Can I weld this tooth directly to my bucket?
A: No. The 9N4252 is a replaceable, pin-on tooth designed to be attached to a weld-on or bolt-on adapter (shank). Welding the tooth directly destroys its heat-treated properties and makes future replacement impossible.
