Springs provide controlled force throughout the engine, and valve springs in particular are among the hardest-worked components in it. This group covers valve springs, injector and governor springs, compression and tension springs in fuel system components, and the spring elements in tensioners and relief valves. Valve springs are the safety-critical item: as a spring loses free length or develops fatigue cracking, valve float or valve-to-piston contact becomes possible. On generating sets running at constant speed, springs see a very high and consistent cycle count, which makes fatigue a more predictable concern than on variable-speed applications.

A generating set running at fixed speed accumulates a very high and uniform cycle count on its valve springs, making fatigue failure a predictable rather than random risk.
Measure free length and test the load at the specified installed height against the published figures. Replace any spring with corrosion pitting or squareness error.
Yes. Mixing a new spring with fatigued ones produces uneven valve train loading and inconsistent seating pressure across cylinders.
