Rear Roller for P&H 2800 Electric Shovel | K1801.18.01.00
Product Overview
The rear roller (also known as lower track roller or track carrier roller) is a critical undercarriage component on your P&H 2800 electric mining shovel. This heavy-duty roller supports the weight of the machine and guides the track chain as it travels around the undercarriage. Positioned at the rear of the track roller frame, it works in conjunction with the front rollers and idler to ensure smooth track movement and proper weight distribution during loading, digging, and tramming operations.
The P&H 2800 is a mining shovel renowned for its durability and productivity in large-scale mining operations worldwide. This genuine P&H rear roller (Part No. K1801.18.01.00) is engineered to exacting OEM specifications for perfect fit, reliable performance, and maximum service life in demanding mining environments.
This is a genuine P&H original equipment part.

- Use new bolts and hardware - Torque to specification
Installation Steps
- Position machine on level ground, block tracks securely
- Relieve track tension (if required for access)
- Clean roller area thoroughly
- Remove mounting bolts securing old roller
- Remove old rear roller
- Clean mounting surface on track roller frame
- Inspect mounting holes for damage
- Install new genuine P&H rear roller (K1801.18.01.00)
- Apply thread locker if specified
- Torque mounting bolts to P&H specifications
- Grease roller fittings (if applicable)
- Restore track tension (if adjusted)
- Test track operation in forward and reverse
Post-Installation
- Verify roller rotates freely
- Check for unusual noise during track operation
- Inspect for proper track alignment
- Re-torque bolts after initial operation (if specified)
IMPORTANT: Installation must only be performed by qualified mining equipment technicians following procedures in the P&H 2800 Workshop Manual.
Maintenance Recommendations
Interval
Maintenance Task
Daily
Visual inspection for damage, unusual noise
