Step-by-Step Installation Guide:

Preparation and Safety Measures:

Before you begin, ensure you have all the necessary tools, safety gear, and workspace ready. Safety is paramount throughout the installation process.

Removing the Existing Crankshaft:

  1. Begin by draining the engine oil completely. Unscrew the oil drain plug and allow the oil to drain into a suitable container.
  2. Carefully disassemble components obstructing access to the crankshaft, such as the transmission, flywheel, and pulleys.

Preparing for the Upgrade:

  1. Thoroughly clean the mating surfaces of the engine block to ensure a precise fit for the new crankshaft.
  2. Apply a light coating of engine oil to the main bearing journals and crankshaft lobes to facilitate initial lubrication.

Installing the New Ruich Value TD27 Crankshaft:

  1. Gently slide the new Ruich Value TD27 Crankshaft into the engine block, aligning it meticulously with the main bearing journals.
  2. Ensure the crankshaft rotates smoothly without encountering obstructions or resistance.
  3. Position the main bearing caps over the crankshaft journals and secure them using the specified torque value provided in the manufacturer’s instructions.

Torquing and Achieving Balance:

  1. Utilize a torque wrench to tighten the main bearing cap bolts to the manufacturer’s recommended torque specifications. Follow the prescribed tightening sequence to ensure uniform pressure.
  2. Employ a dynamic balancer to verify the crankshaft’s balance, ensuring optimal engine smoothness and performance.

Reassembly and Testing:

  1. Reassemble the components that were removed during the disassembly phase, including the transmission, flywheel, and pulleys.
  2. Replace the engine oil filter and refill the engine with the recommended quantity of fresh engine oil.
  3. Reconnect the battery and conduct a comprehensive inspection to confirm that all components are securely reinstated.

Startup and Performance Assessment:

  1. Turn the ignition key to start the engine and listen carefully for any unusual noises or vibrations.
  2. Allow the engine to idle for a few moments, ensuring it maintains a smooth and steady operation.
  3. Monitor real-time performance parameters using an OBD-II scanner to compare with manufacturer specifications.
  4. Let the engine warm up while monitoring the coolant temperature gauge, ensuring it reaches the optimal operating range.
  5. Engage the transmission and accelerate the vehicle to assess the engine’s response to throttle inputs.
  6. Perform controlled accelerations to record acceleration times before and after the upgrade.
  7. If available, consider dyno testing for precise horsepower and torque output data.
  8. Make necessary fine-tuning adjustments to optimize air-fuel mixture and ignition timing.
  9. Conduct a comprehensive road test to evaluate overall performance, responsiveness, and smooth acceleration.
  10. Park the vehicle, allowing it to idle and monitoring for any unusual noises or irregularities.
