Hitachi EX2600-6 Excavator 1029150

Drive Wheel (Drive Tumbler) for Hitachi EX2600-6 Excavator | 1029150

Product Overview

The drive wheel (also known as drive tumbler or drive sprocket) is a critical undercarriage component of your Hitachi EX2600-6 mining excavator. Mounted on the output shaft of the travel device (final drive), the drive wheel engages directly with the track chain bushings to propel the 254-ton machine forward or backward. Its segmented design allows for field replacement of individual sections, minimizing downtime in demanding mining operations.

The Hitachi EX2600-6 is a 254-ton class mining excavator with a backhoe operating weight of 254,000 kg and a shovel operating weight of 252,000 kg. It is powered by a Cummins QSKTA50-CE engine producing 1,119 kW (1,500 hp). This genuine Hitachi drive wheel (Part No. 1029150) is engineered to exacting OEM specifications for perfect fit, reliable performance, and maximum service life in demanding mining environments.

This is a genuine Hitachi original equipment part.

Technical Specifications

Please verify exact specifications with your machine’s technical manual or existing component.

Note on Part Number:Part number 1029150 is the drive wheel for the EX2600-6. This is distinct from part number 1029151 (for EX3600-6) and 1029152 (for EX1900-6). Please verify compatibility with your specific machine serial number before ordering.

EX2600-6 Undercarriage Overview

The Hitachi EX2600-6 features a reinforced undercarriage system designed for extreme mining conditions. According to the EX2600-6 Workshop Manual, the undercarriage components are documented in SECTION 3 UNDERCARRIAGE of the service manual:

Key Undercarriage Features

• Cast steel structures integrated into the center track frame to avoid stress concentration and increase reliability
• High-mounted compact travel motors protected from rock damage
• Optional travel motor guards provide additional protection
• Rigid box design resists bending and twisting forces
• The EX2600-6 is also compatible with EX2500-5 and EX2500-6 undercarriage components

Function & Operation

Operating Principle

1. Travel device (final drive) output shaft rotates the drive wheel
2. Drive wheel teeth engage track chain bushings
3. Drive wheel rotation pulls track chain around undercarriage
4. Track shoes contact ground, propelling the 254-ton machine
5. Segmented design allows tooth section replacement without removing travel device

Wear Mechanism

As the track system operates, the following progressive wear occurs:

• Drive wheel teeth wear from engagement with track bushings
• “Hook” formation develops on teeth as wear progresses
• Worn drive wheels accelerate track chain bushing wear
• Regular inspection prevents damage to travel device output shaft seals

Torque Specifications

The EX2600-6 service manual includes specific torque procedures for sprocket mounting bolts. Proper torqueing sequence is critical for safe operation and must be followed precisely.

Compatible Hitachi Models

Important:The drive wheel 1029150 is confirmed to be compatible with EX2500, EX2500-5, EX2500-6, EX2600-6BH, and EX2600-6LD models. Please verify your machine’s serial number with our parts department to ensure correct compatibility.

Installation Guidelines

Critical Requirements

1. Verify part numbermatches your machine’s requirements
2. Prepare adequate heavy lifting equipment- Drive wheel segments are heavy
3. Support machine securelywith track blocked
4. Relieve track tensionbefore removal using track adjuster
5. Use new mounting bolts- Torque to specification
6. Follow torque procedurein EX2600-6 service manual

Installation Steps

1. Position machine on level ground, block tracks securely
2. Relieve track tension using track adjuster grease valve
3. Remove track chain or create slack for drive wheel access
4. Clean drive wheel area thoroughly
5. Remove mounting bolts securing drive wheel segments
6. Remove worn drive wheel segments
7. Clean travel device output flange mounting surface
8. Inspect output flange and seals for damage
9. Install new genuine Hitachi drive wheel segments (1029150)
10. Apply thread locker to mounting bolts if specified
11. Torque mounting bolts to Hitachi specifications following the proper sequence
12. Apply track tension to specification using track adjuster
13. Reinstall track chain if removed
14. Test track operation in forward and reverse at low speed
15. Re-torque mounting bolts after initial operation

Torque Specifications

Post-Installation

• Verify smooth track operation in both directions
• Check for proper drive wheel-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 EX2600-6 Workshop Manual, specifically SECTION 3 UNDERCARRIAGE - Travel Device. The torque procedure for sprocket mounting bolts is specifically referenced in the manual and must be followed precisely.

Maintenance Recommendations
