Cylinder Head Gasket 12420482 (Genuine DEUTZ/MWM Part)
Part No. 12420482 is a multi-layer steel cylinder head gasket specially designed for DEUTZ MWM gas engines. It fits TBG/TCG 2020/2032 and other related models. As an original genuine part, it seals between cylinder head and cylinder block to isolate gas, cooling water and engine oil.
1. Basic Information
- Part Number: 12420482
- Name: Cylinder Head Gasket
- Brand: DEUTZ / MWM
- Applicable Models:
DEUTZ MWM TBG/TCG 2020/2032 series gas engines
DEUTZ TCG 620 V12/V16/V20 series
BF6M1013, BF4M2012 industrial, power generation and marine engines
- Function: Seals combustion chambers, water passages and oil passages to prevent air, water and oil leakage.
- Matching Valve Stem Diameter: φ8 mm (matched with the complete valve train)
2. Material & Manufacturing Process
- Structure: Multi-Layer Steel (MLS) composite structure (3 layers of stainless steel with high-temperature rubber coating)
- Material:
Core plate: SUS304 stainless steel, high strength and deformation resistance
Surface layer: High-temperature fluororubber coating, resistant to oil, water and gas corrosion
- Surface Treatment: Reinforced stamping on edges and precision punching for all holes to avoid tearing and gas blow-by.
- Operating Temperature: -40℃ ~ +450℃, suitable for high temperature and high explosion pressure conditions of gas engines.
- Compression Rate: 15%–20%, ensuring sealing resilience and compensating for deformation of cylinder block and head.
3. Key Dimensions (Original Standard)
- Overall Length × Width: Approx. 220 × 220 mm
- Thickness (Free State): 2.0 mm
- Cylinder Bore Inner Diameter: φ128 mm (matching 128 mm cylinder bore)
- Bolt Holes: 8 pcs of M12 bolt holes, pitch circle diameter φ190 mm
- Water Holes: 4 pcs of φ20 mm through holes, symmetrically arranged
- Oil Holes: 2 pcs of φ10 mm through holes near the camshaft side
- Unit Weight: Approx. 0.8 kg
4. Functions & Features
- High-pressure Sealing: Combined multi-layer steel and rubber coating withstands gas explosion pressure of 12–15 MPa and prevents air leakage.
- High Temperature Durability: Resists thermal shock and creep, no aging or leakage during long-term operation.
- Precise Fit: All holes are fully compatible with original cylinder block and head, no modification required for installation.
- Deformation Resistance: Rigid stainless steel core plate compensates for preload of cylinder head bolts and thermal deformation.
- Complete Matching: Recommended to replace together with valves, valve seat inserts, valve guides, valve stem seals, valve spring 12300239 and rocker arm assembly 12420479.
5. Replacement & Compatibility
- Genuine Alternative Part No.: 12420482 (No updated replacement part)
- Recommended Aftermarket Brands: , ELRING, AJUSA. The number of layers, thickness, cylinder bore diameter and bolt hole position must be strictly matched.
6. Installation Instructions
- Inspection & Cleaning: Ensure flat surfaces of cylinder block and head are free of scratches, deformation and oil stains. Check the gasket for damage and wrinkles.
- Installation Direction: Place the marked side towards the cylinder head with the "TOP" mark facing upward, and align all holes with water and oil passages.
- Bolt Torque: Tighten bolts diagonally in three steps. Final torque: 120±10 Nm (cold condition).
- Flatness Control: The flatness of cylinder head shall not exceed 0.05 mm/m. Grind and repair if out of tolerance.
- Complete Replacement: Replace together with valves, valve seat inserts, valve guides, valve stem seals, valve springs and rocker arm assembly to guarantee reliable sealing performance.
