Introduction to the CAT 246
The Caterpillar 246 is a compact track loader (CTL) known for its versatility and ability to perform a wide range of tasks in industries like construction, landscaping, and agriculture. With its powerful engine, robust hydraulic systems, and smooth track operation, the CAT 246 is a popular choice for operators seeking reliable performance in tight spaces. However, like any heavy equipment, it can encounter issues such as engine failure, which can be both costly and time-consuming to resolve.
One such issue is a "blown motor" or engine failure, which may leave operators wondering what went wrong and how to fix it. In this article, we'll explore common causes of engine failure in the CAT 246, troubleshooting steps, and solutions to get your machine back to work.
What Does a "Blown Motor" Mean?
A "blown motor" is a term commonly used to describe an engine that has suffered a catastrophic failure. The failure can occur due to various reasons, but most often, it involves the engine components being damaged beyond repair. In the case of the CAT 246, a blown motor can result from issues such as overheating, low oil pressure, coolant leaks, or a failure in the engine's internal components like the pistons, crankshaft, or valves.
Symptoms of a blown motor include:
When dealing with a suspected blown motor in a CAT 246, it's important to troubleshoot the issue systematically. Here are some steps you can take:
Dealing with a blown motor in the CAT 246 can be a stressful experience, but understanding the potential causes and troubleshooting methods can help you diagnose and resolve the issue efficiently. By maintaining regular service intervals, checking critical systems, and addressing any issues promptly, you can extend the life of your CAT 246 and avoid costly repairs. Whether you choose to repair or replace the engine, addressing the root cause and following up with preventive maintenance will keep your machine running at peak performance for years to come.

In the case of the CAT 246, a blown motor can result from issues such as overheating, low oil pressure, coolant leaks, or a failure in the engine's internal components like the pistons, crankshaft, or valves.
Symptoms of a blown motor include:
- A sudden loss of power or performance
- Excessive smoke from the exhaust
- Strange knocking or banging noises from the engine
- A drastic decrease in fuel efficiency
- Warning lights or error codes on the dashboard
- Overheating
- Overheating is one of the most common reasons for engine failure. If the cooling system is not functioning properly, the engine can reach temperatures that exceed safe operating limits. This can cause the engine oil to break down, leading to poor lubrication and potential damage to the engine’s internal parts. A blown head gasket, cracked cylinder heads, or warped engine block are often the result of overheating.
- Common causes of overheating include coolant leaks, a malfunctioning radiator, a blocked cooling system, or a failed thermostat.

- Oil Starvation
- Insufficient oil or low oil pressure can lead to metal-on-metal contact within the engine, causing wear and tear on vital components. Over time, this can lead to the failure of the motor. Low oil levels can be caused by leaks, poor maintenance, or an improper oil change schedule.
- Without proper lubrication, critical engine parts like the bearings, pistons, and crankshaft can overheat and seize, leading to catastrophic engine failure.

- Fuel Contamination
- Contaminated fuel can cause significant damage to the engine, particularly if dirt, water, or debris enters the fuel system. This can result in incomplete combustion, leading to power loss, rough running, or severe engine damage.
- Fuel system components such as the fuel injectors, fuel pump, and filters may become clogged or damaged as a result of poor-quality fuel.

- Lack of Regular Maintenance
- One of the leading causes of engine failure in the CAT 246 and other machinery is neglecting regular maintenance. Failing to perform necessary oil changes, air filter replacements, and coolant checks can cause premature wear on engine components, leading to a higher likelihood of failure.
- Over time, carbon buildup can also accumulate within the engine, causing issues with valve function and overall performance.

- Faulty Wiring or Electrical Issues
- In some cases, the motor failure can stem from an electrical issue, such as a malfunctioning sensor, a shorted wire, or an issue with the alternator or starter motor. Electrical issues may not directly damage the motor, but they can cause the engine to misfire or fail to start, which may appear like a blown motor.

When dealing with a suspected blown motor in a CAT 246, it's important to troubleshoot the issue systematically. Here are some steps you can take:
- Check for Warning Codes
- Modern machines like the CAT 246 are equipped with diagnostic systems that can give you a hint about the cause of the failure. Using an onboard diagnostic tool or CAT's proprietary diagnostic software, you can scan for any error codes or fault messages that can help pinpoint the issue.
- Common error codes related to engine failure may involve low oil pressure, overheating, or electrical malfunctions.

- Inspect the Oil
- Check the oil level and condition. If the oil is low, top it up with the correct type of oil and check for any visible signs of contamination, such as metallic shavings. If the oil appears thick or gritty, this may indicate engine wear and a possible blown motor.
- Check for oil leaks around the engine, which could result in oil starvation.
