Solution

1. Preparation

• Gather tools and parts.

  3. Check the condition of the chain guides and tensioner.

4. Replace Timing Chain (if necessary)

• Sub-steps:
  1. Align the engine to top dead center (TDC).
  2. Remove the old timing chain, using a chain tool if necessary.
  3. Place the new timing chain on the sprockets, ensuring proper alignment with timing marks.
