[MikePhua]

When considering the purchase of a used Bobcat 1845C skid-steer loader, it’s essential to understand the key features, common issues, and maintenance requirements that come with owning this popular piece of heavy equipment. The Bobcat 1845C, a versatile machine known for its maneuverability and power, has been a staple in construction, landscaping, and other industries where compact equipment is needed for heavy lifting and digging tasks.
Overview of the Bobcat 1845C
The Bobcat 1845C was designed to offer operators a combination of performance, durability, and versatility in a compact skid-steer format. Released during the early 1990s, the 1845C features a high lift design, making it suitable for a range of attachments and ideal for jobs requiring high reach. As a part of Bobcat's 1800 series, the 1845C provides an auxiliary hydraulic system, which is critical for powering a variety of attachments such as augers, trenchers, and grapples.
With its hydraulic lift system and four-wheel drive, the 1845C is capable of maneuvering in rough terrain, allowing for superior traction and lift capacity. Its 45-horsepower engine enables it to carry out tough jobs in demanding environments, all while maintaining the compact size that Bobcat is known for. This skid-steer loader typically comes with a lifting capacity of about 1,500 lbs, with a bucket breakout force of approximately 2,500 lbs.
Key Features of the Bobcat 1845C

1. Powerful Engine: Powered by a 4-cylinder diesel engine (usually a Kubota V2203 or similar), the 1845C is well-equipped to handle tough jobs in diverse industries. It provides the power needed for both lifting and moving heavy materials while maintaining fuel efficiency for extended work periods.
   
2. Hydraulic System: The auxiliary hydraulic system is one of the standout features of the 1845C. With an output of approximately 16 gallons per minute (GPM), this system can power various attachments effectively, from augers to snow blowers. This makes the 1845C an all-season, all-terrain machine.
   
3. High-Lift Design: One of the most useful attributes of the 1845C is its high-lift arms, which allow operators to load or unload materials at greater heights than traditional skid-steer loaders. This feature improves efficiency and ease of operation, particularly for tasks like lifting pallets or dumping materials into trucks.
   
4. Compact Size: Despite its lifting capabilities, the 1845C maintains a compact footprint, which allows it to work in tight spaces where larger machines can't operate effectively. This makes it a favorite among contractors working in urban or confined job sites.
   
5. Durability and Ease of Maintenance: Bobcat machines are well-known for their durability and low maintenance costs. Regular checks and fluid changes help extend the life of the 1845C, while its simple design ensures that most parts are easily accessible for repairs.
   

Common Issues with the Bobcat 1845C
While the Bobcat 1845C is a solid and reliable machine, like all used equipment, it comes with its fair share of potential issues that buyers should be aware of. Here are some common problems to watch for:

1. Hydraulic Leaks: One of the most frequent issues with older 1845C models is hydraulic leaks. This can be caused by worn hoses, seals, or damaged cylinders. A leaking hydraulic system not only reduces performance but can also lead to significant operational downtime if not addressed promptly.
   
2. Electrical Issues: Electrical systems in older machines can become prone to failure due to age. Problems can include faulty connections, worn-out wires, or issues with the alternator or battery. It's essential to inspect the electrical components thoroughly before purchase to avoid costly repairs.
   
3. Engine Performance: Since the 1845C is powered by a diesel engine, problems with engine performance can arise if the machine hasn’t been regularly maintained. Issues such as poor fuel delivery, clogged filters, or a weak starter may be signs that the engine needs attention.
   
4. Drive Motors and Axles: The drive motors and axles in the 1845C are critical components that should be inspected for wear. If the machine has been used for heavy-duty work without proper maintenance, the axles could be worn down or the drive motors could show signs of excessive wear. These parts can be expensive to replace, so it's essential to look for any irregular noises or difficulty with movement during a test run.
   
5. Cooling System: Overheating can be a common issue in older models, especially if the cooling system is clogged or malfunctioning. Keeping the radiator clean and ensuring that the engine coolant is regularly topped up is crucial to preventing overheating problems.
   

Buying a Used Bobcat 1845C: What to Look For
When purchasing a used Bobcat 1845C, it’s essential to conduct a thorough inspection to assess its condition. Here are some important factors to consider:

1. Inspect the Hydraulic System: Ensure the hydraulic system operates smoothly and there are no signs of leakage. Check for any sluggish movement or uneven lifting, which could indicate issues with the hydraulic pump or cylinders.
   
2. Engine and Maintenance History: Ask for a record of the machine’s maintenance history. A well-maintained 1845C will typically have regular oil changes, air filter replacements, and hydraulic fluid checks. Make sure the engine starts easily and runs smoothly, without knocking or excessive smoke.
   
3. Frame and Lift Arms: Check the lift arms for any signs of cracking, rust, or damage. Since the 1845C is a high-lift model, it’s important that the frame and lift mechanism are structurally sound to handle the added stress of lifting heavy loads.
   
4. Check the Tires and Undercarriage: Since the 1845C is a four-wheel drive machine, the tires must be in good condition for optimal performance. Inspect the tread depth and wear pattern on the tires. The undercarriage should be free from excessive wear and tear that could hinder movement or create safety concerns.
   
5. Operational Test: Conduct an operational test to ensure that the loader is fully functional. This includes checking for proper lifting, smooth movement of the arms, responsive controls, and the effective operation of attachments.
   

Maintenance Tips for the Bobcat 1845C
Regular maintenance is key to keeping the Bobcat 1845C running efficiently and extending its lifespan. Here are some tips:

• Regular Fluid Changes: Change engine oil, hydraulic oil, and filters at the recommended intervals to keep the machine running smoothly.
  
• Inspect Hydraulics: Look for leaks regularly, and keep the hydraulic hoses clean and free of damage.
  
• Grease the Loader: Ensure that all moving parts, including the lift arms and joints, are properly greased to prevent wear and tear.
  
• Clean Air Filters: Dirty air filters can lead to poor engine performance, so clean or replace the air filters regularly.
  
• Check for Software Updates: If the machine is equipped with any diagnostic software, make sure it is up to date and functional to catch potential issues early.
  

Conclusion
The Bobcat 1845C is a reliable and versatile skid-steer loader that offers great performance for a wide range of tasks. When buying a used unit, attention to detail is essential, particularly when checking for common issues like hydraulic leaks, engine performance, and wear on key components like the lift arms and drive motors. Proper maintenance, such as regular oil changes, hydraulic fluid checks, and tire inspections, will ensure that your Bobcat 1845C continues to serve you well on the job site for years to come.
If well-maintained, a used Bobcat 1845C can provide exceptional value and performance, making it a great addition to any construction, landscaping, or agricultural fleet.
