What is the correct torque specification for the flywheel?

The correct torque specification for the flywheel is 55 ft-lbs because this value is typically determined by the manufacturer based on the specific engine design and the materials used in the flywheel assembly. Proper torque is crucial because it ensures that the flywheel is secured tightly enough to handle the operational stresses without risk of loosening, which can lead to serious mechanical failure or damage during engine operation. Following the manufacturer's specifications helps maintain the integrity of the engine and supports optimal performance.

Other torque specifications, while they might seem plausible, may not provide the necessary clamping force required for your specific engine model. If the torque is set too high, it could lead to cracking the flywheel or damaging the crankshaft, while too low a torque could result in the flywheel losing its grip during operation, risking severe damage to the engine. Hence, adhering to the specified 55 ft-lbs is critical for both safety and functionality.
