Briggs & Stratton Head Bolt Torque Sequence
When it comes to assembling or reassembling the cylinder head of a Briggs & Stratton engine, it is crucial to follow the correct torque sequence for the head bolts. This ensures proper tightening and helps maintain the integrity of the engine’s combustion chamber. The head bolt torque sequence should be followed diligently to prevent any potential damage or leaks.
Head Bolt Torque Specifications
To achieve the recommended torque for the head bolts, it is essential to use a torque wrench. Below is a table outlining the head bolt torque specifications for Briggs & Stratton engines, measured in foot-pounds (ft. lbs.) and Newton-meters (Nm):
| Bolt Number | Torque (ft. lbs.) | Torque (Nm) |
|---|---|---|
| 1 | 10 | 13.6 |
| 2 | 15 | 20.3 |
| 3 | 20 | 27.1 |
| 4 | 25 | 33.9 |
| 5 | 30 | 40.7 |
| 6 | 35 | 47.5 |
Head Bolt Torque Sequence
To ensure proper tightening and distribution of torque, the head bolts should be tightened in a specific sequence. Follow the steps below:
1. Start by tightening bolt number 1 to the specified torque (10 ft. lbs. or 13.6 Nm).
2. Move to bolt number 2 and tighten it to the specified torque (15 ft. lbs. or 20.3 Nm).
3. Proceed to bolt number 3 and tighten it to the specified torque (20 ft. lbs. or 27.1 Nm).
4. Continue this pattern, moving to bolts 4, 5, and 6, and tightening them to their respective torque specifications.
5. Once all bolts have been tightened, repeat the sequence, gradually increasing the torque until the final torque value is reached.
By following this torque sequence, you ensure that the head bolts are evenly tightened, minimizing the risk of leaks or damage to the engine.
Conclusion
Properly torquing the head bolts of a Briggs & Stratton engine is crucial for maintaining its performance and reliability. By adhering to the recommended torque specifications and following the correct sequence, you can ensure a secure and leak-free seal for the cylinder head. Remember to use a torque wrench and take your time to achieve the desired torque values accurately. With the right approach, you can confidently assemble or reassemble the cylinder head of your Briggs & Stratton engine.
