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, governor and actuator springs, compression and tension springs in gas train and control components, and the spring elements in tensioners and relief valves. Valve springs on continuous-duty gas engines accumulate an extremely high cycle count at constant speed, making fatigue a scheduled-replacement concern rather than an unpredictable failure. MWM specifies spring renewal as part of the cylinder head overhaul cycle, and springs are replaced as complete sets so that valve train loading stays even across cylinders.
AMS Parts supplies a wide range of springs components for MWM engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.
Constant-speed continuous running accumulates a very high and uniform cycle count, making fatigue predictable. Scheduled replacement at head overhaul avoids failure in service.
Yes. A new spring alongside fatigued neighbours produces uneven valve train loading and inconsistent seating pressure across the cylinders.
Valve float or valve-to-piston contact becomes possible, which on a continuously running engine can cause extensive damage before the fault is noticed.
