Product Features & Engineering Advantages
  • Complete Engine Overhaul Solution for Large Mining Engines - This comprehensive gasket kit includes every seal and gasket needed for a complete engine rebuild on the 50-liter K50 engine platform. From the cylinder heads to the oil pan, all mating surfaces are covered, eliminating the need to source individual components separately.
  • OEM-Spec Cylinder Head Gasket - The cylinder head gaskets are manufactured to original equipment specifications, ensuring proper combustion sealing and compression. Designed to withstand the extreme pressures generated by this large-displacement V16 engine.
  • Precision Gear Room Cover Gasket - Includes the critical gear room cover gasket (OEM 3177160) engineered specifically for K50 engines. This component serves as the primary seal between the engine block and gear room cover, ensuring zero oil leakage under high pressure.
  • High-Pressure and High-Temperature Performance - Designed to withstand extreme operating conditions with operating pressure up to 20 bar and temperatures up to 150°C. All gaskets maintain sealing integrity under the most demanding mining applications.
  • Robust Construction with OE-Level Geometry - Manufactured with precision tolerances for perfect alignment with K50 engine blocks. Reinforced bolt holes resist torque without deformation, critical for the high-stress environment of large mining engines.
  • Tested to Extreme Durability Standards - All gaskets undergo rigorous testing including thermal cycles and pressure cycling to ensure long-term reliability in continuous mining operations.
  • Complete PT Fuel System Sealing - Includes all necessary seals for the Cum mins PT fuel system. PT injectors operate at high pressures requiring precision sealing for optimum combustion.
  • Compatible with K50 and K2000E Variants - Suitable for both K50 and K2000E engine variants, including KTA50 and KTTA50 configurations. Works with both naturally aspirated and turbocharged versions.

Installation Note
The gear room cover gasket and cylinder head gaskets are critical components that seal the combustion chambers and gear train on K50 engines. When installing a new gasket kit on a Cum mins K50 engine, follow these critical guidelines:
  1. Always verify the correct gasket kit based on engine serial number.
  2. Prepare all mating surfaces thoroughly before installation.
  3. Follow the specific torque sequence in the factory service manual.
  4. Cylinder head bolts must be replaced according to factory specifications - do not reuse old head bolts.
  5. Clean all mating surfaces thoroughly before installation.
  6. Professional installation is recommended due to the precision required.
Warning: Improper installation can lead to coolant leaks, oil leaks, compression loss, and severe engine damage. Always verify proper torque specifications and tightening sequences.
