Challenges in Restoring Old Equipment
Restoring field-find equipment is not without its challenges. Machines that have been left out in the elements are usually in rough shape, with significant issues to address. The most common problems found in field finds include:
1. Rust and Corrosion
Rust is one of the most significant challenges when dealing with old machinery. The steel and iron components of equipment exposed to rain, snow, and humidity can develop corrosion that weakens the structure and affects the machine's functionality.
Solution:
Engines and hydraulic systems in old equipment may have seized up over time, especially if the machinery was not properly stored. A seized engine can result from the oil or coolant in the system drying up, causing internal components to seize and corrode.
Solution:
Old electrical systems can be extremely problematic in field-find machines. Wiring can deteriorate, and components like alternators or starters can fail. Similarly, the fuel system may suffer from clogging due to the buildup of sediment and rust in the fuel tank and lines.
Solution:
For tracked equipment like bulldozers or excavators, the undercarriage and tracks can take a significant amount of abuse. Over time, these can become heavily worn or even break down completely, making the equipment unusable.
Solution:
If you’ve found a piece of machinery in the field that you wish to restore, there are several key steps to follow. While the restoration process will vary depending on the equipment, some common steps will help ensure a successful project:
1. Assess the Machine's Condition
Before starting any work, it's essential to assess the equipment thoroughly. Identify which parts are usable and which need to be replaced. A complete inspection should include:
2. Gather the Right Tools and Parts
Once you've assessed the equipment, gather the necessary tools and replacement parts. It's crucial to have the right tools for the job, as using improper tools can cause further damage.
Before diving into any mechanical repairs, it's best to start with a deep clean. Remove debris, dirt, and grime from the machine, especially around the engine and hydraulic systems. This will give you a better view of any potential problems.
Once the machine is clean, assess the condition of the engine, hydraulic components, and undercarriage. If any parts are severely worn, it's better to replace them at this stage than to risk damaging other components.
4. Engine and Hydraulic Repair
After cleaning, start with the most critical areas: the engine and hydraulic systems. For the engine, you’ll likely need to check the oil, replace filters, and potentially rebuild the engine if it’s seized.
Hydraulic systems can often be the most expensive to repair, so be sure to inspect hoses, cylinders, and pumps for damage. Leaking hydraulic lines are common in older machines and should be replaced promptly to avoid further issues.
5. Tackle the Undercarriage
For tracked equipment, the undercarriage is essential for performance. Inspect the tracks and replace any parts that are cracked or excessively worn. It’s a good idea to re-lubricate rollers and tracks to prevent further rust and wear.
6. Electrical and Fuel System Fixes
Electrical systems in older machinery can be a headache. Wiring should be replaced or rewired as necessary. Ensure that fuses, relays, and the battery are in working condition. Likewise, cleaning the fuel system, including the tank, fuel lines, and injectors, is necessary to get the engine running smoothly.
Conclusion: The Reward of Reviving the Past
Restoring a field-find piece of equipment is both a challenging and rewarding task. It takes patience, skill, and the right knowledge to turn a rusty, forgotten machine into a functional piece of equipment once again. Not only will you breathe new life into a machine, but you'll also preserve a piece of industrial history. Whether you’re restoring a classic bulldozer, tractor, or excavator, each field-find tells a unique story and, with the right care, can continue to serve for years to come.

Challenges in Restoring Old Equipment
Restoring field-find equipment is not without its challenges. Machines that have been left out in the elements are usually in rough shape, with significant issues to address. The most common problems found in field finds include:
1. Rust and Corrosion
Rust is one of the most significant challenges when dealing with old machinery. The steel and iron components of equipment exposed to rain, snow, and humidity can develop corrosion that weakens the structure and affects the machine's functionality.
Solution:
- Cleaning and Sandblasting: A thorough cleaning process is necessary to remove surface rust. Sandblasting or pressure washing can be used to strip away the rust and prepare the surface for painting or coating.
- Rust Removal Treatments: Special rust removers and converters can be used to treat areas that are too corroded for conventional cleaning, especially in the engine compartment and undercarriage.
Engines and hydraulic systems in old equipment may have seized up over time, especially if the machinery was not properly stored. A seized engine can result from the oil or coolant in the system drying up, causing internal components to seize and corrode.
Solution:
- Lubrication and Penetrating Oil: In many cases, a combination of lubricants and penetrating oils (such as PB Blaster or WD-40) can be used to loosen stuck components. This should be done gradually, allowing the oils to penetrate over several days.
- Engine Overhaul: For more severe cases, a complete engine teardown might be required to clean out rust, replace worn parts, and restore the engine to working condition.
Old electrical systems can be extremely problematic in field-find machines. Wiring can deteriorate, and components like alternators or starters can fail. Similarly, the fuel system may suffer from clogging due to the buildup of sediment and rust in the fuel tank and lines.
Solution:
