Over-tightened bolts can cause as much damage and injury as bolts left too loose. Always tighten bolts to factory specifications. Kohler engines can require as much as 400 foot-pounds of torque. Torque is a measurement of the energy released under a specific pressure. The torque wrench itself has graduated measurements you can follow as you tighten the bolt.
Use your specific machine's model and serial number to determine the correct torque range for your engine.
Check each bolt and nut with the torque wrench during final assembly. Stay within the manufacturer range for safe operation.
