The Role of the Drive Sprocket in the Undercarriage System

The sprocket works interdependently with other components:

• • Bottom rollers support the machine weight and guide the chain underside.
  • Top rollers (carrier rollers) keep the upper chain taut.
  • Idlers guide the front chain loop and maintain tension.
  • Track chain connects everything — the sprocket's teeth engage the chain links, so any mismatch or wear here accelerates wear across the entire system.

Why You Should Replace The Drive SprocketSooner Rather Than Later

Export buyers often ask: “How do I know when it’s time?” Look for rounded teeth, visible grooves, chain skipping under load, unusual grinding noise, or excessive play at the hub. Delaying replacement can:

• Accelerate track chain stretch (a $3,000+ fix on these machines)
• Cause premature roller and idler failure
• Increase fuel burn by 10–20% due to slippage
• Lead to job-site downtime that costs more than the part itself

 Our Manufacturing & Factory Advantages

We use high-strength cast alloy steel (equivalent to industry-standard grades like 50Mn/35MnB) for this sprocket. Casting gives us the edge in creating complex tooth profiles and uniform material structure, while induction hardening pushes the teeth to HRC 52–58 for deep, lasting resistance to abrasion and impact. Every piece goes through:

• Mold design and pouring for precise geometry
• Heat treatment to lock in hardness without brittleness
• CNC final machining for tight hub and bolt tolerances
• Ultrasonic inspection and hardness testing on every batch

FAQ

Q: What chain pitch does this sprocket work with? A: Designed for standard John Deere 300-series pitch (~90–100mm); 17 teeth ensure proper mesh. If your chain is non-OEM, send us a photo or specs for confirmation.

Q: Will it fit my 333E with aftermarket tracks? A: Usually yes, but serial and chain details matter—contact us with your machine info.

Q: Shipping and export concerns? A: We pack with rust inhibitors and export crates; worldwide shipping with tracking included.
