product description

 

Caterpillar E70B Drive Sprocket – Technical Specifications

 

 

1. Part Number & Compatibility

  • OEM Part Number: Typically 4Y-3702 (varies by serial number; verify via Cat® SIS).
  • Application: Designed exclusively for the Caterpillar E70B compact excavator, compatible with its undercarriage track chain assembly.

2. Material & Manufacturing

  • Material: High-tensile alloy steel (SAE 4140), heat-treated to achieve:
    • Surface hardness: HRC 55-60 (induction hardened).
    • Core toughness: Impact-resistant to prevent cracking.
  • Process: Precision forged + CNC-machined; tooth profile laser-verified for optimal track link engagement.

 

  • 3. Key Dimensions

    • Tooth Count: 11 teeth (may vary by production year).
    • Pitch: 152mm (6"), matching E70B track chain pitch.
    • Bore Diameter: Ø80mm±0.02mm (fits sprocket shaft with tight tolerance).
    • Mounting Bolts: M20×1.5, torque specification: 450-500 N·m.
  •  

4. Performance Features

  • Wear Resistance: Hardened tooth surface (depth: 3-5mm) for extended service life in abrasive conditions (e.g., rock, gravel).
  • Anti-Shock Design: Optimized root fillet radius to reduce stress concentration.
  • Sealing Integration: Machined grooves for dual-lipped radial seals (prevents grease leakage/contamination).

 

5. Maintenance Guidelines

 

 

  • Replacement Interval: Inspect every 2,000–3,000 service hours; replace if tooth thickness is worn beyond 15%.

  • Lubrication: Grease via zerk fittings every 250 hours using NLGI #2 lithium-based grease.

  • Paired Replacement: Recommended to replace track chains simultaneously to avoid uneven wear/meshing issues.
