The Bobcat 1835 is a well-regarded skid steer loader known for its durability and versatility in construction and landscaping tasks. Over time, like any piece of equipment, it may face engine issues or may simply reach the point where an engine replacement is needed to restore optimal performance. For those interested in giving their 1835 a new lease on life, repowering—replacing the original engine with a newer, more powerful one—can be a highly effective solution.
Repowering a Bobcat 1835 isn’t a small task, but with careful planning, the right tools, and a bit of mechanical know-how, it can be a rewarding upgrade. This article walks you through the considerations and steps involved in repowering a Bobcat 1835 skid steer loader, including engine options, steps, and tips for a successful project.
Understanding the Bobcat 1835 and Engine Considerations
Before diving into repowering, it’s essential to understand the existing machine’s specifications and needs. The Bobcat 1835 originally came equipped with a variety of engine options, including the 4-cylinder, 46-horsepower Perkins diesel engine. This engine served the 1835 well, but after years of use, the engine might lose power, become inefficient, or simply fail.
Repowering, in this case, involves replacing the old engine with a newer, potentially more powerful model. However, it's crucial to match the replacement engine with the skid steer’s design and intended use. Factors like engine compatibility, size, output capacity, and the machine’s existing systems (cooling, hydraulics, etc.) need to be considered to avoid complications down the line.
Choosing the Right Replacement Engine
Choosing the right replacement engine is the most critical part of the repowering process. Not all engines will be a perfect fit for the Bobcat 1835, and it's vital to choose one that aligns with the machine's capacity, weight, and operational needs.
Repowering a Bobcat 1835 requires a clear understanding of the mechanics involved. Below is a general outline of the steps you’ll need to follow:
Repowering a Bobcat 1835 can be a challenging task, particularly when it comes to ensuring that the new engine is fully compatible with the machine’s existing systems. Here are some common challenges and ways to address them:
Repowering a skid steer like the Bobcat 1835 can be costly. The cost will depend on factors like the type of engine you choose, whether modifications are required, and if professional labor is needed. However, repowering is often more cost-effective than purchasing a new skid steer, especially if the machine frame and hydraulics are still in good condition. On average, engine replacements for a machine like the 1835 can range from a few thousand dollars to over ten thousand, depending on the brand and model of the engine.
Conclusion
Repowering a Bobcat 1835 can breathe new life into an aging machine, improving performance and extending its service life. It’s an excellent way to get more value out of your equipment without the expense of purchasing a brand-new unit. However, it requires careful planning, the right tools, and knowledge to ensure a smooth and successful installation. With the proper engine selection and a meticulous approach to installation, your repowered Bobcat 1835 can continue to serve your needs for years to come.

- Engine Compatibility
- The replacement engine must fit within the machine's frame and be compatible with the existing components such as the transmission, cooling system, and fuel system. Many users opt for engines from well-known manufacturers like Perkins, Kohler, or Kubota, which offer reliable performance and are easier to source.

- Engine Power
- You may want to consider upgrading to a more powerful engine if the 1835 will be used for more demanding tasks. An increase in horsepower, however, should be balanced with the machine’s frame strength and hydraulic capabilities. A more powerful engine may strain the system if not paired correctly.

- Fuel Efficiency and Emissions
- Newer engines often come with better fuel efficiency and lower emissions, making them more environmentally friendly and cost-effective in the long run. It's also worth considering whether the new engine meets current emission regulations, especially if the machine will be used in urban or regulated areas.

- Cooling and Hydraulics
- When selecting an engine, ensure that the cooling system (radiator size, capacity) and hydraulic system are capable of handling the new engine’s output. Overloading these systems can cause overheating or system failure.
