How To Install A Crankshaft With New Bearings - (Hyundai / Kia 2.4 GDI) - Short Block Rebuild Part 3

Introduction

This tutorial will guide you through the process of installing a crankshaft with new bearings in a Hyundai or Kia 2.4 GDI engine. This step is crucial for ensuring the longevity and proper function of your engine after a rebuild. Following the steps outlined here will help you avoid common pitfalls and achieve a successful installation.

Step 1: Prepare the Engine Block

• Ensure the engine block is clean and free of debris.
• Check that the crankshaft and new bearings are compatible with your engine model.
• Apply a thin layer of engine assembly lube to the bearings to reduce friction during installation.

Step 2: Insert the Crankshaft

• Carefully place the crankshaft into the engine block.
• Ensure that the crankshaft journals align properly with the bearings.

Step 3: Position the Bearing Caps

• Align the bearing caps over the crankshaft.
• Hand-tighten the cap bolts into the block to avoid cross-threading.

Step 4: Secure the Bearing Caps

• Once the cap bolts are seated, use a light hammer to gently tap the caps. This helps to ensure they are fully seated against the block.
• You should feel the caps bottom out; verify this before proceeding.

Step 5: Tighten the Cap Bolts

• Hand-tighten the bolts again to ensure they are snug.
• Follow a crisscross pattern for torqueing the bolts to the manufacturer's specifications.
  • Torque specification: 18.1 - 21.7 LBS or 24.5 - 29.4 NM.

Step 6: Check Crankshaft Rotation

• After torqueing, manually rotate the crankshaft.
• Ensure it rotates freely without any hang points or resistance.

Step 7: Install Piston Cooling Oil Jets

• If applicable, install the piston cooling oil jets (oil squirters).
• Use the same torque specifications as mentioned earlier to secure these components.

Conclusion

You have successfully installed a crankshaft with new bearings in your Hyundai or Kia 2.4 GDI engine. This crucial step in the short block rebuild process ensures your engine operates efficiently. After this, you can proceed with additional engine assembly steps, ensuring each component is installed correctly for optimal performance.
