Fort Collins Begins Relife Project on J-2 Contracting's 844K Loader
Rebirth of a Powerhouse: The J-2 Contracting 844K Relife Project
The 4Rivers Equipment team in Fort Collins is currently undergoing an extensive John Deere Relife on an 844K Wheel Loader for J-2 Contracting. By stripping the machine to its frame and installing a suite of remanufactured and rebuilt components, we are transforming a high-hour veteran into a "factory-fresh" asset capable of an additional 12,000 hours of peak performance.
Anatomy of a Relife: The Disassembly Phase
A project of this scale, led by Service Technician Tyler Bretz, began on March 1, 2026. The initial phase is a total teardown, leaving only the bare chassis. This meticulous process ensures that every internal system can be inspected and revitalized.
The "Stripping" Process Includes:
- Removal of all exterior panels, fenders, hood, and the operator cab.
- Extraction of the "heart" and "brain": the engine, transmission, and cooling pack.
- Removal of the hydraulic tank, main pumps, and all internal wiring and hoses.
- Removal of the massive front and rear axles.
Precision Cleaning and Framework
Once the machine is reduced to its frame, the Fort Collins crew utilizes dry ice blasting. This innovative cleaning method uses solid $CO_2$ pellets to strip away years of accumulated grease, dirt, and debris without damaging the metal surface or leaving behind secondary waste.
Following the cleaning, the frame receives a fresh coat of high-durability paint and new articulation pins and bushings. This ensures that the mechanical "joints" of the loader move with the same precision they did the day the machine was originally manufactured.
Restoring the Power: Component Installation
The core of the Relife value proposition lies in the power train. Under the oversight of Gary Medill, the team is integrating factory-spec remanufactured components to guarantee "Day 1" performance.
Major Component Overhauls:
- Engine & Transmission: Installation of genuine John Deere Reman units.
- Hydraulics: A new main hydraulic pump and a complete replacement of all wiring harnesses and hoses to prevent future leaks or electrical shorts.
- Axle Rebuilds: Unlike some shops, the Fort Collins team performs a full onsite rebuild of both front and rear axles, ensuring the driveline is ready for heavy-duty cycle times.
Why J-2 Contracting Chose a Relife Over Replacement
For a production-class machine like the 844K, a Relife is a strategic financial tool. By choosing to revitalize their existing loader, J-2 Contracting is securing another 12,000 operational hours at a fraction of the cost of a new machine.
The Benefits of the 4Rivers Relife Program:
- Cost Efficiency: Provides a "like-new" loader without the heavy capital expenditure of a new purchase.
- Proven Durability: The frame and heavy castings are built to last through multiple life cycles.
- Enhanced Specs: The machine returns to the field with the latest updates and refreshed aesthetics, including a professional paint job and new decals.
Common Questions About the 844K Relife (FAQ)
What is the expected timeline for this project?
The J-2 Contracting project is estimated to take approximately 200 working hours, spanning 9 to 10 weeks, with a target completion date of May 3, 2026.
How does a Relife differ from a standard repair?
A standard repair fixes what is broken. A Relife is a proactive, complete overhaul of all major systems (engine, transmission, hydraulics, and axles) to reset the machine's life clock back to zero.
Is the 844K a good candidate for this process?
Yes. John Deere "K-Series" loaders have incredibly robust frames. When the structural integrity is sound, replacing the internal "wear" components is the most efficient way to manage a heavy equipment fleet.
Will the machine have a warranty?
Yes. Genuine John Deere Reman components typically carry their own warranty, and 4Rivers Equipment stands behind the quality of our technician’s assembly and rebuild work.
