Steps to Torque the Head Bolts
To ensure the proper torque of the head bolts on your Briggs and Stratton 18.5 Intek engine, follow these steps:
1. Start by cleaning the head bolt threads and the corresponding holes in the engine block to remove any dirt, debris, or oil residue.
2. Insert the head bolts into their respective holes, ensuring they are properly aligned.
3. Begin tightening the head bolts in a crisscross pattern. Start with bolt number 1, then move to bolt number 2, and so on.
4. Use a torque wrench to tighten each head bolt to the specified torque value. Gradually increase the torque in multiple stages to ensure even distribution.
5. Repeat the crisscross tightening pattern until all head bolts are torqued to the recommended specifications.
6. Double-check the torque of each head bolt to ensure they are within the specified range.
7. Once all head bolts are properly torqued, you can proceed with the reassembly of other engine components.
By following these steps and using the correct torque specifications, you can ensure the head bolts on your Briggs and Stratton 18.5 Intek engine are tightened to the appropriate level, promoting optimal engine performance and reliability.
Remember, it is essential to consult the engine’s specific manual or contact Briggs and Stratton directly for any additional information or clarification regarding torque specifications or maintenance procedures.
