CUMMINS
3417507 Flywheel Housing (HOUSING,FLYWHEEL) is a large cast connecting housing specially matched for Cummins series diesel engines. Installed at the rear end of engine cylinder block, it acts as the transition connecting the engine and gearbox. It wraps and protects flywheel, clutch and related rotating components, bears assembly load and isolates vibration between power unit and transmission.
This flywheel housing solves common failures such as housing crack, mounting hole deformation, oil leakage and abnormal transmission vibration caused by impact overload, long-term vibration fatigue and aging damage of old housings, an essential heavy-duty spare part for engine major overhaul.
High-Strength Thickened Cast Integral Body
High tensile cast iron one-piece casting, thickened stress concentration area, strong impact resistance and anti-fatigue performance, no crack under long-term heavy load bumpy operation.
Precision CNC Machined Flange & Mount Holes
All connecting surfaces, bolt holes and gearbox matching flange are precisely processed, flat sealing surface avoids oil seepage, uniform bolt force prevents local deformation.
Integrated Dust & Splash Protection Structure
Full surrounding enclosure design blocks dust, muddy water and engine oil splash, reduce wear of flywheel and clutch assembly, extend service life of transmission parts.
Optimized Vibration Isolation Design
Reinforced rib layout disperses engine high-frequency vibration, reduces resonance noise between engine and gearbox, improves whole vehicle driving stability.
Wide Temperature & Load Adaptability
Stable mechanical performance under -40℃ ~ +135℃, no thermal deformation under long-time high-temperature engine compartment working environment.
Standard Matching Installation Size
Overall dimension 119cm69cm23cm, net weight 21.999KG, fully matches Cummins engine rear cylinder block and supporting gearbox, no secondary cutting or drilling required.
Strict Multi-Process Factory Inspection
All flywheel housings pass flaw detection, flatness test and load stress test, stable batch quality for engine overhaul factories, logistics fleets and machinery maintenance stores bulk procurement.
