Drive Sprocket for Hitachi EX3600-6 Excavator | 1029151
Product Overview
The drive sprocket (also known as drive tumbler or track sprocket) is a critical undercarriage component of your Hitachi EX3600-6 mining excavator. Mounted on the output shaft of the travel device (final drive), the sprocket engages directly with the track chain bushings to propel the 362-ton machine forward or backward. Its segmented design allows for field replacement of individual sections, minimizing downtime in demanding mining operations.
The Hitachi EX3600-6 is a 362-ton ultra-class mining excavator powered by two Cummins QSKTA60-CE engines producing 1,450 kW (1,944 HP) each. The backhoe configuration has an operating weight of 361,000 kg (795,900 lbs), while the loading shovel configuration weighs 359,000 kg (791,500 lbs). This genuine Hitachi drive sprocket (Part No. 1029151) is engineered to exacting OEM specifications for perfect fit, reliable performance, and maximum service life.
This is a genuine Hitachi original equipment part.

Key Undercarriage Features
- Cast steel center track frame integrated to avoid stress concentration
- Segmented sprocket design allows individual section replacement without removing final drive
- High-mounted compact travel motors protected from rock damage
- Rigid box design resists bending and twisting forces
Function & Operation
Function
Description
Torque Transmission
Transfers rotational torque from travel device to track chain
Track Engagement
Sprocket teeth engage track bushings to propel machine
Wear Surface
Designed as sacrificial wear component protecting travel device
Direction Control
Forward/reverse rotation determined by travel motor direction
Operating Principle
- Travel device (final drive) output shaft rotates the drive sprocket
- Sprocket teeth engage track chain bushings
- Sprocket rotation pulls track chain around undercarriage
- Track shoes contact ground, propelling the 362-ton machine
- Segmented design allows tooth section replacement without removing travel device
Wear Mechanism
As the track system operates, the following progressive wear occurs:
- Sprocket teeth wear from engagement with track bushings
- "Hook" formation develops on teeth as wear progresses
- Worn sprockets accelerate track chain bushing wear
- Regular inspection prevents damage to travel device output shaft seals

Installation Guidelines
Critical Requirements
- Verify part number matches your machine's requirements
- Prepare adequate heavy lifting equipment - Sprocket segments are heavy
- Support machine securely with track blocked
- Relieve track tension before removal using track adjuster
- Use new mounting bolts - Torque to specification
- Apply thread locker if specified by service manual
Installation Steps
- Position machine on level ground, block tracks securely
- Relieve track tension using track adjuster grease valve
- Remove track chain or create slack for sprocket access
- Clean sprocket area thoroughly
- Remove mounting bolts securing sprocket segments
- Remove worn sprocket segments
- Clean travel device output flange mounting surface
- Inspect output flange and seals for damage
- Install new genuine Hitachi sprocket segments (1029151)
- Apply thread locker to mounting bolts if specified
- Torque mounting bolts to Hitachi specifications
- Apply track tension to specification using track adjuster
- Reinstall track chain if removed
- Test track operation in forward and reverse at low speed
- Re-torque mounting bolts after initial operation

Post-Installation
- Verify smooth track operation in both directions
- Check for proper sprocket-bushing engagement
- Inspect for unusual noise during track operation
- Re-check track tension after initial operation
- Re-torque mounting bolts after 50 hours (if specified)
IMPORTANT:Installation must only be performed by qualified mining equipment technicians following procedures in the EX3600-6 Workshop Manual, specifically SECTION 3 UNDERCARRIAGE - Group: Drive Tumbler. Proper torqueing procedure for sprocket mounting bolts is critical for safe operation.
