Exhaust Valve 5-12552034-0 for ISUZU C240 Engine — a verified direct-fit, 34.2 × 8 × 115.8 mm, 45° seat angle, chrome-plated outlet valve engineered for wholesale and rebuild supply.
The exhaust valve with OEM number 5-12552034-0 is a verified direct-fit replacement for ISUZU C240 diesel engines. It is a critical component in the cylinder head valve train, responsible for sealing the combustion chamber and regulating the release of exhaust gases during the exhaust stroke.
The exhaust valve opens to allow burned gases to exit the cylinder and closes to seal the combustion chamber during the compression and power strokes. It operates under extreme thermal and mechanical stress and must resist oxidation, warping, and seat recession. A failed exhaust valve causes compression loss, rough running, power drop, and potential engine damage.
- Real Bench Test Data: Head diameter 34.2 mm, stem diameter 8 mm, overall length 115.8 mm, seat angle 45° — verified against OEM specification.
- Proven Durability: Net weight 0.09 kg, material STD (OEM-grade alloy), chrome-plated surface per supplier data — verified by material test report.
- Installation Success Rate: 100% direct fitment into C240 cylinder head — confirmed across engine rebuild orders.
- OEM Cross-Reference Verified: Replaces 5-12552034-0 / 5125520340; cross-refs 5125520342, 5125520380, V91498 (AE), R4535/RCR (FRECCIA).
- Certification: ISO/TS16949 certified where applicable — verified by supplier certificate.
- Engine misfire or rough idle (compression loss)
- Reduced power and poor fuel economy
- Excessive valve train noise (ticking/clicking)
- Burned or warped valve face (overheating)
- Valve seat recession causing clearance loss

- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" vs. "long" pushrod variants exist within the MC828264 family.
- Always provide the VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
