  Navigating the Risks and Rewards of Buying Auction Trucks with Significant Repair Needs
Posted by: MikePhua - 09-24-2025, 04:01 PM - Forum: General Discussion - No Replies

Purchasing a truck at an auction can be an attractive option for those seeking a bargain, but it comes with its own set of risks, particularly when the vehicle requires significant repairs. The potential to acquire equipment at a fraction of the market price is enticing, but buyers must exercise caution to avoid falling into costly repair traps that can quickly erode the value of their purchase.
This article delves into the considerations involved when buying a truck at an auction that comes with a hefty repair bill. We’ll explore the benefits, pitfalls, and strategies to mitigate risks when faced with such purchases. Additionally, we will examine how to assess the real value of auction trucks and determine whether the price paid truly reflects the cost of necessary repairs.
The Appeal of Auction Trucks
Buying trucks at auctions, whether for personal use, fleet expansion, or resale, can be an appealing option. Auctions often feature trucks from various sectors, including construction, delivery, and transportation, providing buyers with a wide selection of vehicles at competitive prices. Auctions, especially those conducted by government agencies, fleet owners, or financial institutions, can present opportunities to secure well-maintained vehicles that are still in their prime years.
However, what makes these trucks particularly attractive is the price. Many auction trucks start with low reserve prices, creating the perception of a great deal. But the reality can be more complicated, especially when the vehicle is in need of substantial repairs or has hidden mechanical issues that may not be immediately visible during the auction inspection.
The Risks of Auction Trucks with Big Repair Bills
When a truck comes with a significant repair bill, the cost can easily surpass the initial purchase price. While these repairs may seem straightforward in theory, they often involve complex issues that require professional attention, specialized parts, and considerable time to address. Let’s break down the key risks associated with buying auction trucks that require substantial repairs:

  1. Unforeseen Repair Costs: Even with an estimate or a rough idea of repair costs, it’s challenging to determine the full scope of the work needed until the truck is thoroughly inspected by a mechanic. The actual repair costs could be higher than expected, particularly if there are hidden issues such as engine problems, transmission failure, or damage to the undercarriage.
  2. Downtime and Operational Delays: Once purchased, an auction truck with extensive repair needs may be out of service for an extended period. This downtime can be costly, particularly for businesses that rely on the vehicle for daily operations. In some cases, waiting for parts to arrive or for repairs to be completed can create significant delays, impacting the bottom line.
  3. Quality of Repairs: If the repairs aren’t performed to a high standard, they could lead to recurring issues down the line. Whether the repairs are done by the buyer or by a third-party mechanic, there’s always a risk that substandard work will result in further breakdowns and additional expenses.
  4. Resale Value: If the goal is to resell the truck, substantial repairs may impact the resale value, even if the truck has been repaired. Buyers will typically expect a significant discount for a truck that was previously damaged or required major repairs, which could limit profitability when the vehicle is eventually resold.
How to Assess the True Value of an Auction Truck
While it’s tempting to focus on the low initial price of an auction truck, buyers must take several steps to ensure they understand the true value of the vehicle before placing a bid. Below are key factors to consider:
  1. Get a Pre-Purchase Inspection: Even though an auction might not allow buyers to conduct full inspections, it's crucial to assess the truck’s condition as thoroughly as possible. If the auction allows for previews or test drives, take full advantage of these opportunities to examine the vehicle. Bring along a mechanic or a knowledgeable professional who can spot potential problems before bidding.
  2. Understand the Scope of Repairs: Before purchasing, gather information on the types of repairs the truck needs. If the truck is being sold “as is,” be sure to ask for documentation that details the repairs required. This may include records of past repairs and any estimates or service history. Even if the auction provides limited information, use the truck’s VIN (Vehicle Identification Number) to obtain further details on its history.
  3. Evaluate Repair Costs: While a basic understanding of the repair costs is important, obtaining estimates from trusted mechanics is even better. This will give you a more accurate idea of the total cost of bringing the truck into working condition. Additionally, consider the cost of downtime during the repair process, which could impact your overall business operations.
  4. Factor in the Cost of Ownership: Don’t just look at the upfront price. Factor in all the costs associated with ownership—insurance, fuel, regular maintenance, and repairs. A truck that requires frequent repairs or has a history of mechanical issues could end up being more expensive in the long run than purchasing a truck in better condition for a slightly higher price.
  5. Research Similar Models: Compare the auction truck to similar models on the market. Are there comparable trucks available for sale that are in better condition? What are their prices? This can help you determine whether the auction truck is genuinely a bargain or if it’s better to look elsewhere.
Strategies for Reducing Risks
If you find yourself interested in an auction truck with significant repair needs, here are some strategies to reduce the risks associated with the purchase:
  1. Bid Only If You’re Prepared for Repairs: If you decide to bid on a truck with a large repair bill, be prepared for the possibility that it may take time and money to bring it back to full functionality. Set aside a repair budget and time frame for getting the truck up and running.
  2. Work with a Trusted Mechanic: Establish a relationship with a reliable mechanic who can provide ongoing advice and support when it comes to the maintenance and repair of auction trucks. A trusted mechanic can also help you assess whether the repairs are worth undertaking.
  3. Use Auction Conditions to Your Advantage: Some auctions allow for returns or provide partial warranties, while others sell vehicles as-is without any guarantees. Be sure to understand the terms and conditions of the auction before you buy, as they can impact your ability to get a refund or return the vehicle if it turns out to be a lemon.
  4. Consider Warranty and Extended Coverage: If the auction truck is still under warranty or eligible for an extended warranty, it may be worthwhile to purchase that additional coverage to offset some of the repair costs.
Conclusion
While buying a truck at an auction can be a great way to acquire equipment at a low price, it’s crucial to consider the repair costs and potential challenges that come with the vehicle. A truck with a significant repair bill can quickly turn from a bargain into a financial burden, so it’s essential to assess the vehicle carefully, understand the costs involved, and be prepared for the necessary repairs.
By conducting thorough research, getting professional inspections, and evaluating all associated costs, buyers can navigate the auction world more confidently. With the right approach, even a truck that needs repairs can still be a worthwhile investment, but only if the full scope of work is clearly understood beforehand.

  Case 855D Loader Hydraulic Control Valve Challenges and Solutions
Posted by: MikePhua - 09-24-2025, 04:00 PM - Forum: Troubleshooting & Diagnosing - No Replies

The Case 855D and Its Role in Mid-Size Earthmoving
Case Construction Equipment, a division of CNH Industrial, has been producing wheel loaders since the 1950s. The 855D, introduced in the late 1980s, was part of Case’s D-series lineup, designed to offer high breakout force, reliable hydraulics, and simplified serviceability for contractors and municipalities. With an operating weight around 28,000 lbs and a bucket capacity of 3.5 cubic yards, the 855D was widely used for roadwork, aggregate handling, and site preparation.
Its hydraulic system was built around a gear-type pump and a multi-section control valve assembly, responsible for directing fluid to the lift, tilt, and auxiliary circuits. While robust in design, the control valve has become a focal point for maintenance and troubleshooting as these machines age.
Terminology Notes

  • Control valve: A hydraulic component that regulates flow direction and volume to actuators like lift cylinders and tilt rams.
  • Spool valve: A sliding cylindrical element inside the control valve that opens and closes fluid passages.
  • Load check valve: Prevents hydraulic fluid from reversing direction under load, maintaining cylinder position.
  • Float function: Allows the bucket to follow ground contours without hydraulic resistance, useful in grading.
Common Symptoms of Valve Malfunction
Operators of aging 855D loaders often report issues such as:
  • Bucket or lift arms drifting down when parked
  • Jerky or delayed response during lift or tilt
  • Inability to hold load position under pressure
  • Hydraulic fluid bypassing internally, causing overheating
  • Float function failing to engage or disengage properly
These symptoms typically point to internal leakage, worn spool lands, damaged seals, or contamination within the valve body.
Root Causes and Diagnostic Strategies
The control valve on the 855D is a multi-section assembly, with each section dedicated to a specific function. Over time, the following issues may arise:
  • Spool wear due to lack of lubrication or contaminated fluid
  • O-ring and seal degradation from heat and age
  • Scoring inside the valve bore from metal particles
  • Weak load check springs or stuck poppets
  • Misadjusted linkage or detent mechanisms
To diagnose valve issues:
  • Perform a pressure test at each circuit port under load
  • Check for external leakage around valve body and fittings
  • Inspect spool movement for binding or excessive play
  • Use infrared thermography to detect hotspots from internal bypass
  • Disassemble and inspect valve sections for scoring and seal condition
A Story from the Midwest
In 2010, a county road crew in Iowa noticed their Case 855D loader was struggling to hold the bucket in position during snow loading. The arms would slowly drop even with the engine off. After ruling out cylinder seal failure, they pulled the control valve and found the lift spool had worn lands and a cracked load check seat. A rebuilt valve section and fresh seals restored full function. The crew noted that “the loader felt like it gained ten years of life overnight.”
Repair and Replacement Options
Depending on the severity of wear, operators have several options:
  • Rebuild individual valve sections using OEM or aftermarket kits
  • Replace entire valve assembly with remanufactured unit
  • Upgrade to newer-style valves with improved sealing and float control
  • Retrofit auxiliary hydraulic lines with external flow control valves
When rebuilding:
  • Use Viton or polyurethane seals for better heat resistance
  • Hone valve bores to remove scoring before reassembly
  • Replace detent balls and springs to restore float and hold functions
  • Flush hydraulic system thoroughly to prevent recontamination
Preventive Maintenance Recommendations
To extend the life of the control valve:
  • Change hydraulic fluid every 1,000 hours or annually
  • Replace filters every 250–500 hours depending on duty cycle
  • Inspect linkage and spool movement monthly
  • Grease control linkages and pivot points regularly
  • Monitor system pressure and temperature during operation
Adding magnetic suction strainers and bypass filtration can reduce particulate load and extend valve life.
Parts Availability and Restoration Tips
While Case no longer produces the 855D, parts remain available through CNH dealers and aftermarket suppliers. Key components like spools, seals, springs, and valve bodies can be sourced or rebuilt.
Restoration tips:
  • Label hydraulic lines before disassembly to avoid cross-connection
  • Use torque specs from factory service manuals during reassembly
  • Pressure test rebuilt valve before installation
  • Upgrade to modern quick-connect fittings for easier service
Some owners have retrofitted newer control valves from Case 721 or 821 models, though this requires custom brackets and hose routing.
Final Thoughts

The logging industry has always been driven by advancements in technology that enable more efficient, safer, and faster processing of timber. One of the innovations that greatly impacted the way trees were felled and processed was the development of the feller delimber machines. By the 1970s, machines designed to fell trees, remove their branches, and prepare them for transportation were becoming a staple in modern forestry operations.
In this article, we’ll explore the development of feller delimbers, specifically focusing on machines built in Timmins, Ontario, during the early 1970s, and their impact on the logging industry. The introduction of these machines marked a significant shift in how forestry work was conducted and set the stage for future innovations in forestry machinery.
What is a Feller Delimber?
A feller delimber is a piece of heavy equipment used in the forestry industry. It is designed to perform two primary tasks:

  1. Felling: The process of cutting down a tree by severing its trunk.
  2. Delimbing: Removing the branches from the trunk of the tree.
These machines are crucial for making logging operations more efficient, as they allow for faster processing of trees compared to manual labor. Instead of requiring multiple pieces of equipment or numerous workers to handle various tasks, a feller delimber combines these processes into one machine, streamlining operations and reducing labor costs.
The Evolution of Feller Delimber Machines in the 1970s
The 1970s saw the emergence of more advanced and specialized feller delimbers. Prior to this period, logging was done primarily by manual labor or basic machinery. Chainsaws were commonly used to fell trees, and limbing was done by hand or with auxiliary equipment. While these methods were effective, they were slow and labor-intensive.
In Timmins, Ontario, a hub of forestry activity, manufacturers began developing and improving heavy-duty machines that could handle both felling and limbing efficiently. These machines were designed to increase productivity and reduce the physical toll on workers. By automating much of the process, feller delimbers helped to accelerate the pace of logging operations, making them more cost-effective for companies.
Timmins, which was home to several logging equipment manufacturers, was well-positioned to produce these machines. The city's proximity to vast forested areas meant that it was not only an ideal location for the production of feller delimbers but also a critical point for testing and refining these machines.
Key Features of 1970s Feller Delimber Machines
Feller delimbers from the 1970s were significant improvements over previous logging machinery. They were designed with several key features that made them highly effective in the field:
  1. Hydraulic Systems: Hydraulic technology allowed for precise control of the machine's arms and cutting equipment. This innovation made the process of felling and limbing much faster and more efficient.
  2. Delimbing Heads: Early feller delimbers in the 1970s featured specialized delimbing heads designed to grip and strip the branches from the trunks of trees. These heads were equipped with rollers, knives, or shears that helped cut through and remove branches with minimal effort.
  3. Mobility and Power: These machines were mounted on large, all-terrain vehicles, such as tracked vehicles or wheeled chassis, to give them mobility in forested areas. The power needed to perform these tasks was provided by robust engines capable of handling tough forestry environments.
  4. Operator Comfort and Safety: As the equipment was being developed, manufacturers began to consider the comfort and safety of operators. The machines featured enclosed cabs that protected operators from falling debris and harsh weather conditions, and improved ergonomics for longer shifts.
Timmins, Ontario: A Hub for Forestry Equipment Innovation
Timmins, Ontario, located in the heart of Canada’s forest industry, became a critical location for the development of logging machinery during the 20th century. With the local demand for forestry equipment growing rapidly, the town became a focal point for innovation. It was here that some of the first feller delimbers of the modern era were built, and many of the machines from the 1970s bear the hallmarks of Timmins’ ingenuity.
The region’s manufacturers played an essential role in the evolution of logging equipment, and many of these companies focused on developing machines that addressed the specific needs of local forestry operations. The harsh terrain of Canada’s northern forests made equipment durability and efficiency a priority.
In the 1970s, as logging companies pushed for more advanced technology, Timmins-based manufacturers responded with machinery that could handle large-scale operations more effectively. This was the era when companies began to specialize in building machines for specific tasks—such as the feller delimber—and were able to achieve major technological breakthroughs.
Impact on the Logging Industry
The introduction of feller delimbers revolutionized the logging industry by streamlining the process of felling and delimbing trees. Before the development of these machines, the felling and limbing of trees was a tedious and dangerous process. Workers would fell a tree using a chainsaw and then remove the branches by hand or with separate equipment. This was a time-consuming and physically demanding job, particularly in the rough terrain of Canada’s vast forests.
Feller delimbers allowed logging companies to complete tasks more quickly and efficiently. Instead of relying on multiple workers and machines for felling and limbing, a single machine could do both jobs, dramatically reducing labor costs and increasing productivity. These machines also allowed operators to work in more challenging environments, such as dense forests or areas with rugged terrain.
By automating the process of felling and limbing, these machines also increased safety on the job site. The operator could remain safely in the cab, reducing the risk of accidents that were common with manual labor. This was particularly important as logging operations grew larger and more complex.
Conclusion
The development of feller delimbers in the 1970s, particularly those built in Timmins, Ontario, played a pivotal role in transforming the logging industry. These machines combined felling and delimbing into one efficient process, increasing productivity and safety while reducing costs. The innovations in hydraulic systems, mobility, and operator safety made feller delimbers essential pieces of equipment in the modern forestry landscape.
As technology continues to evolve, logging machines today are far more sophisticated than the models of the 1970s. However, the groundwork laid by the feller delimbers of that era remains influential in the industry, and Timmins’ legacy as a hub for forestry equipment innovation is still evident in the machines used today.
