Daily Driving My Tank After Giving it a 1000HP Engine

Introduction

In this tutorial, we'll walk through the process of upgrading a tank by replacing its engine with a powerful 12-valve Cummins diesel engine. This guide is based on the journey of transforming a military tank into a high-performance vehicle, as demonstrated in Westen Champlin's video. You'll learn how to source an engine, perform the installation, and troubleshoot common issues along the way.

Step 1: Sourcing the Engine

• Identify the engine type you want to install. In this case, a 12-valve Cummins diesel engine was chosen for its durability and power.
• Locate a suitable engine for repurposing. Consider options like salvage yards or online marketplaces where used engines are sold.
• Ensure the engine is in good condition but understand that it may need a rebuild. Look for engines that have not been excessively damaged.

Step 2: Rebuilding the Engine

• Disassemble the engine carefully to inspect all components.
• Replace necessary parts to ensure reliable performance:
  • New rings
  • Bearings
  • Gaskets
  • Pistons (if needed)
• Perform a thorough cleaning of all parts before reassembly.
• Use a montage method for reassembly if desired for efficiency, but ensure that all bolts are properly tightened and secured.

Step 3: Preparing the Tank for the Engine Installation

• Use appropriate equipment to move the tank, such as a skid loader, winch, chains, and a trailer.
• Securely load the tank onto the trailer for transport to your workspace.
• Remove the old engine from the tank:
  • Use the skid loader as an engine uninstalling device.
  • Ensure the area is clear and safe before proceeding.

Step 4: Installing the New Engine

• Position the newly rebuilt Cummins engine in the tank.
• Secure the engine using appropriate bolts and hardware.
• Connect the drive shaft to the engine, ensuring all fittings are tight.
• Install the radiator and intercooler, and complete the cooling system setup.

Step 5: Setting Up the Fuel and Electrical Systems

• Install the fuel system components necessary for the Cummins engine.
• Ensure that the wiring is properly connected to support engine functions.
• Double-check connections for any potential leaks or loose fittings.

Step 6: Testing the Engine

• Before starting, ensure all systems (fuel, electrical, cooling) are correctly set up.
• Adjust the idle speed if the engine does not start initially. A low idle can prevent proper fuel flow.
• Start the engine:
  • If the engine does not start, try giving it throttle to help it crank.
  • Monitor for any unusual noises or leaks during the initial run.

Step 7: Driving and Troubleshooting

• Take the tank for a test drive to evaluate performance.
• Pay attention to any overheating issues or abnormal behavior during operation.
• If the tank struggles, investigate potential causes, such as overheating transmission lines or insufficient power delivery.

Conclusion

Upgrading a tank with a new engine can be a rewarding project that enhances its performance significantly. Key takeaways include the importance of properly sourcing and rebuilding the engine, ensuring all systems are correctly installed, and being prepared for troubleshooting during the testing phase. Next steps could involve further modifications, such as improving the transmission or upgrading the suspension for better handling. Enjoy the thrill of driving a uniquely powered tank!
