How to Prevent Flywheel Key Shearing: Understanding the Causes and Solutions

Flywheel keys shear off due to excessive vibration or poor manufacturing.

What Causes Flywheel Key To Shear

A flywheel key is a small piece of metal that is inserted between the flywheel and crankshaft of an engine to connect them in order for the engine to operate correctly. Unfortunately, over time, the flywheel keys can become sheared due to improper installation, corrosion, or simply due to wear and tear.

Due to the extreme temperatures and pressures that are found inside an engine, even a small amount of added stress can cause the key to become sheared. A faulty or mismatched flywheel key may not provide adequate alignment and torque distribution leading to high vibration levels in the motor which can cause elongation of the crankshaft and premature crankpin failure.

Corrosion can also be an issue if there is insufficient lubrication on the mating surfaces. In this case, dirt and oil that seeps through may cause rusty spots on the flywheel or crankshaft resulting in brittleness which weakens both components’ strength while increasing the likelihood of shearing when they are pressed together with a new key.

Lastly, excessive vibration can lead to fatigue in both the flywheel and crankshaft components which will eventually create tiny cracks that propagate across both components until it causes a complete shearing of the key essentially ruining both parts.

To prevent this from happening, it’s recommended that all tightening procedures be performed as prescribed by your engine’s manufacturer as well as regular inspection for signs of rusting and wear during routine maintenance schedules. Properly maintaining your equipment will ensure safe operation over long periods of time without any problems regarding worn out keys!
