|---|---|---|
| Bolt 1 | 80-85 | 108-115 |
| Bolt 2 | 80-85 | 108-115 |
| Bolt 3 | 80-85 | 108-115 |
| Bolt 4 | 80-85 | 108-115 |
| Bolt 5 | 80-85 | 108-115 |
| Bolt 6 | 80-85 | 108-115 |
| Bolt 7 | 80-85 | 108-115 |
| Bolt 8 | 80-85 | 108-115 |
Steps to Torque the Head Bolts
Follow these steps to properly torque the head bolts of a Cat C13 engine:
- Clean the threads of the head bolts and the bolt holes using a suitable cleaning agent.
- Apply a small amount of engine oil or lubricant to the threads of each head bolt.
- Start by tightening each head bolt to 40 ft. lbs. (54 Nm) in a crisscross pattern.
- Next, torque each head bolt to 70 ft. lbs. (95 Nm) in the same crisscross pattern.
- Finally, torque each head bolt to the specified torque of 80-85 ft. lbs. (108-115 Nm) in the same crisscross pattern.
- Double-check the torque of each head bolt to ensure they are properly tightened.
Following these torque specifications and steps will help ensure the proper installation and sealing of the cylinder head on a Cat C13 engine. It is important to refer to the manufacturer’s guidelines and consult a professional if you have any doubts or concerns.
