The Case 1835C is a popular skid steer loader, known for its rugged durability and versatility on construction sites. Powered by the TMD-20 engine, this machine has become a staple in many fleets due to its compact design and reliability. However, like all machinery, the Case 1835C is not immune to engine-related issues. When the engine starts having trouble, it can cause delays and expensive repairs. In this article, we’ll dive into common engine troubles that operators might face with the TMD-20 engine, how to diagnose these issues, and ways to prevent them in the future.
Understanding the Case 1835C and TMD-20 Engine
The Case 1835C skid steer loader is powered by the TMD-20, a small yet efficient engine designed for heavy-duty work. This machine has earned its place in the industry because of its compact size, making it ideal for tight spaces, but still offering the power needed for most tasks on a job site.
The TMD-20 engine is a four-cylinder, naturally aspirated unit that runs on diesel fuel. It’s designed for high performance and fuel efficiency, but like any engine, it is susceptible to wear and tear. Over time, issues such as poor maintenance, wear on key components, and fuel system problems can arise.
Common Engine Issues with the Case 1835C TMD-20
When an engine begins to fail, it’s usually a sign that something isn’t functioning as it should be. For the TMD-20 engine, there are several common issues that can cause trouble. Let’s explore these potential problems and what they might mean for the performance of the Case 1835C.
Proper diagnosis is key to identifying and fixing issues with the TMD-20 engine in the Case 1835C. Here’s how to go about it:
The best way to avoid engine trouble with the Case 1835C TMD-20 is through regular maintenance. Here are some key maintenance tasks that should be performed routinely:
One operator on a busy construction site was working with a Case 1835C that had started to show signs of loss of power and rough running. Initially, the operator ignored the symptoms, assuming they were minor issues. After a few weeks, the machine broke down completely, and the issue was traced to a clogged fuel filter. The engine had been starved of fuel for some time, causing damage to the injectors.
This incident cost the company significant downtime and repair costs. The lesson learned here was simple: regular maintenance and prompt attention to even small issues can prevent larger, more costly problems down the road.
Conclusion: Keeping the TMD-20 Engine in Top Condition
The Case 1835C TMD-20 engine, like all heavy machinery engines, requires attention to detail and regular maintenance to ensure optimal performance. By addressing small issues early on—whether it’s poor fuel delivery, overheating, or excessive smoke—operators can avoid costly breakdowns and extend the life of the engine. Through proper care and regular checks, the TMD-20 engine can continue to power your Case 1835C loader for years to come, ensuring reliable performance and reduced downtime on the job site.

Common Engine Issues with the Case 1835C TMD-20
When an engine begins to fail, it’s usually a sign that something isn’t functioning as it should be. For the TMD-20 engine, there are several common issues that can cause trouble. Let’s explore these potential problems and what they might mean for the performance of the Case 1835C.
- Starting Issues and Poor Idle Performance
- Battery Problems: A weak or dead battery can make it difficult for the engine to start, especially in cold weather. This is often the result of battery age or corrosion at the terminals. Replacing the battery or cleaning the terminals may be all that’s required.
- Fuel Delivery Issues: Another reason for poor starting can be related to the fuel system. A clogged fuel filter, air in the fuel lines, or a faulty fuel pump can prevent the engine from getting the fuel it needs to start. Inspecting and cleaning the fuel lines or replacing a clogged filter can often resolve this issue.
- Loss of Power or Rough Running
- Air Filter Clogging: If the air filter becomes clogged with dust or debris, it will restrict airflow to the engine, causing it to lose power or run unevenly. Regularly replacing or cleaning the air filter can help prevent this.
- Fuel Injector Problems: The TMD-20 relies on fuel injectors to properly atomize fuel for combustion. If these injectors become clogged or damaged, they may not deliver the correct amount of fuel, causing the engine to run poorly. Cleaning or replacing the injectors can restore the engine’s smooth operation.
- Fuel Contamination: If the diesel fuel becomes contaminated with water or dirt, it can cause rough running and poor combustion. This can often be prevented by ensuring proper fuel storage and filtration.
- Overheating and Engine Temperature Problems
- Coolant Leaks: A leaking coolant system can cause the engine to overheat, as the coolant is essential for regulating the engine’s temperature. Inspecting the radiator, hoses, and connections for leaks is a critical step in maintaining the system.
- Radiator Blockage: If the radiator becomes clogged with debris, it won’t be able to effectively dissipate heat, causing the engine temperature to rise. Cleaning the radiator and ensuring proper airflow can prevent overheating.
- Faulty Thermostat: A malfunctioning thermostat may prevent the engine from properly regulating its temperature, leading to overheating. Replacing the thermostat can resolve this issue.
- Excessive Smoke from the Exhaust
- Blue Smoke: Blue smoke typically indicates that oil is being burned in the engine. This could be due to worn piston rings or valve seals, both of which need to be replaced to stop the oil consumption.
- Black Smoke: Black smoke often means that the engine is burning too much fuel. This could be caused by a malfunctioning fuel injector, clogged air filters, or improper fuel-to-air mixture. Replacing the air filter or cleaning the fuel injectors can address this problem.
- White Smoke: White smoke suggests that coolant is leaking into the combustion chamber, possibly due to a blown head gasket. This is a serious issue and often requires the replacement of the head gasket.
Proper diagnosis is key to identifying and fixing issues with the TMD-20 engine in the Case 1835C. Here’s how to go about it:
- Conduct a Visual Inspection: The first step in diagnosing engine problems is performing a visual inspection. Look for obvious signs of leaks, damage, or corrosion around the engine, battery, fuel lines, and exhaust system.
- Check Fluid Levels: Ensure that the engine has the correct levels of oil, coolant, and fuel. Low levels of any of these fluids can lead to engine problems.
- Listen for Unusual Sounds: Pay attention to any unusual noises coming from the engine. A knocking sound could indicate internal damage, while a whining noise could be related to the fuel pump or air intake.
- Use Diagnostic Tools: Many modern skid steers are equipped with diagnostic ports that allow you to connect diagnostic tools. These tools can help identify issues with the engine’s electrical system, sensors, or ECU.
The best way to avoid engine trouble with the Case 1835C TMD-20 is through regular maintenance. Here are some key maintenance tasks that should be performed routinely:
- Change the Engine Oil and Filter Regularly: Regular oil changes help keep the engine running smoothly and prevent damage caused by dirty or old oil. Follow the manufacturer’s recommendations for oil change intervals.
- Replace the Air and Fuel Filters: Clogged filters can cause a variety of engine problems, including loss of power and overheating. Replacing the air and fuel filters regularly is one of the easiest ways to keep the engine running at its best.
- Inspect the Cooling System: Make sure that the coolant is topped up and that the radiator and hoses are in good condition. Clean the radiator regularly to prevent blockages.
- Check the Battery and Electrical System: Clean the battery terminals, check the charge, and ensure the electrical system is functioning properly.
