What We Do: The Gold Standard in Chip Spreader Restoration

We don't just repair your Used Chip Spreader, we revitalize it. At Rocky Mountain Rebuild, we perform everything from a quick fix to a long-term investment.

Whether you're looking for expert repair or a ground-up premium rebuild, our goal is to ensure your machine is ready the moment it hits the job site.


Repair vs. Rebuild: Understanding the Difference

While many shops focus on what is broken now, we focus on what could fail later.

  • A Repair addresses known issues. It is a targeted solution to get a machine back in operation by fixing existing faults. We consult with you, agree on the needs, and fix the machine to good operating condition according to your needs and budget.

We repair pumps, hydraulics, hoses & fittings, hoppers, belts, computers and any other broken parts or systems your chip spreader needs to get back in service. (Click images to enlarge.)


  • The "Chip Ready" Program takes repair work even further.  We perform a full 28 point inspection on your used chip spreader and look not only for what's broken now, but what may be in danger of failing going forward.  Hoses, rubber, hardware, pumps--all will fail at different times  but will usually show signs of critical wear before they fail completely.   Our Chip Ready Program is a specialized repair service where we perform a rigorous inspection and address all critical wear items to ensure your repaired machine is functional, reliable, and "Chip Ready" for the foreseeable future, without the higher cost of a full premium rebuild.

A Premium Rebuild takes on the possibility of future failure and restores and rebuilds a used chip spreader as close as possible to "like new" condition.  Drivetrains and frames tend to have relatively little wear and hours compared to the rest of the machine components.  Therefore we rebuild from the drivetrain and frame up, preserving value where it still exists, while restoring nearly everything else with brand new, premium components.

First we strip our rebuild machines to their essential frame and drivetrain, then completely sandblast down to the bare metal and repaint. We blast rust, wear and old finishes off, repaint everything with premium finishes in our state of the art paint booth, and then rebuild the entire machine to give you a like new machine, for a fraction of the cost. We proactively replace all the wear and tear components throughout the heart of the machine to ensure years of uninterrupted service.  Below is a 20 year old Etnyre Chip Spreader after our rebuild process.

Our Premium Rebuild Process

A premium rebuild is a total transformation.

We strip the machine to its core and replace almost everything—inside and out. Our current standard is a meticulous 1000-man-hour process that takes a machine from teardown to the finish bay in approximately six weeks.

1. Teardown & Inspection

 

We begin with a comprehensive pre-build inspection. We identify any structural issues and perform all necessary welding and fabrication before the machine moves to the next stage.

2. Blast & Paint

To ensure a factory-quality finish, we blast the machine to bare metal and repaint it before reassembly begins. By blasting first, we ensure that abrasive dust never finds its way into your new hydraulic components or wheel ends.

We repaint with premium quality, industrial finish, Jones-Blair HS Acrylithane paint -- using Halliburton Yellow, Black, Red and Grey.  Our paint finish is baked and cured to durable perfection in our onsite paint and heat booth.

3. Component Replacement

Because chip spreaders are hydraulic-heavy and full of wearable components, when we rebuild we replace almost all of the following:

• Pumps, motors, and hydraulic hoses
• Fittings, air valves, and cylinders
• Rollers, rubber seals, and conveyor belting
• Engine hoses, clamps, and electrical wiring

4. Precision Power Train Care

We find that most engines, transmissions and differentials do not require full overhauls. We do a thorough inspection of the engine, the transmission, inspection and reseal if necessary, the differentials, the brakes, replace seals and brake shoes as needed,  and replace seals and components as needed.  With engines, if needed, we do an overhead.  We do an engine inspection, and overhead if needed. To keep costs efficient for our clients, we perform a deep-dive inspection. We dump all fluids and inspect for gear wear or internal debris. If there are no leaks or fluid issues, we maintain the original power train, passing that significant cost saving on to you.    We do inspect everything.  We will do seals, tune ups, hardware, parts replacement as needed. We talk with the client about their desires and fix anything they want as well.

COMPUTER AND ELECTRICAL

 

We are experts in computer and control systems for all major

Chip Spreader Brands, including GEFFS, Etnyre, WH and Rosco.

 

We offer and install the much needed ETNYRE CHIP SPREADER COMPUTER CONTROL SYSTEM UPGRADE package.

While the content below focuses on an Etnyre project, GEFFS is fully qualified to retrofit and install computer and control systems for all major brands of used chip spreaders.

HERE'S A SHORT VIDEO EXPLAINING WHAT'S CONTAINED IN OUR ETNYRE COMPUTER CONTROL SYSTEM UPGRADE

 

We install the computer control system main unit and all the attendant wiring that communicates to components all over the machine, and particuarly the gate and rate control systems. As you can see, the work is extensive and sophisticated and something we’re capable of right here on site.

DRIVER'S STATION

No one appreciates the quality of a Rocky Mountain Rebuild job more than the chip spreader operator.

With the new computer control display updated in the drivers dashboard, new control interfaces, cleaned up wiring, and general aesthetic improvement, the operator's system on this rebuilt etnyre used chip spreader looks, feels and functions as good as new.

With the additional retrofit of the proprietary Etnyre computer control system, even better than new.

The machine enters the finish bay for final assembly. This is where we install the new controls and complete the final mechanical integrations.

Quality Assurance & Accountability

We believe in transparency. Our quality control isn't a final check—it’s a multi-step protocol integrated into every segment of the build. We perform and sign off on inspections at every milestone:
• Pre-Fab & Post-Fab
• Pre-Blast & Post-Blast
• Pre-Paint & Post-Paint
• Pre-Finish & Post-Finish (Final Sign-off)
Every technician is held accountable for their stage of the process, ensuring that the machine you receive meets our exacting standards.
