The Exhaust Valve with OEM number 1003015FE010 is a direct-fit replacement engine valve for JAC N56 and Sunray vehicles equipped with the HFC4DE1-1D / 4DE1-1D (2.7L) diesel engine. This valve controls the release of exhaust gases from the combustion chamber during the exhaust stroke.
Working Principle: The exhaust valve opens during the exhaust stroke to allow burned gases to exit the cylinder into the exhaust manifold. It closes during intake, compression, and combustion to maintain a sealed combustion chamber. Exhaust valves operate under extreme thermal stress and must resist oxidation and deformation at high temperatures.
- Confirmed OEM Number: 1003015FE010 — confirmed across multiple parts catalogs
- Confirmed Part Name: Exhaust Valve (Клапан выпускной / válvula de escape)
- Confirmed Engine Compatibility: 4DE1-1D / HFC4DE1-1D (2.7L diesel)
- Confirmed Vehicle Compatibility: JAC Sunray, JAC N56
- Confirmed Weight: 0.05 kg — per supplier spec
- Confirmed Package Dimensions: 0.11 * 0.03 * 0.03 m — per supplier spec
- Pending Material Specification: Steel grade, heat treatment, and coating not specified in available sources
- Pending Dimensional Data: Valve stem diameter, head diameter, and overall length. One aftermarket source lists 29.05 mm head, 5.95 mm stem, and 107.03 mm height, but this is not OEM-verified
- Pending Bench Test Data: Hardness, thermal fatigue, and sealing — recommend supplying your own test report
- Pending Installation Success Rate: Recommend providing repair order statistics
Critical This is the EXHAUST valve. The corresponding INTAKE valve uses OEM 1003014FE010 — a separate part number. Do not substitute.
- Burned or warped valve (compression loss, misfire)
- Excessive oil consumption (worn valve guides or seals)
- Abnormal exhaust noise or popping
- Visible cracks or erosion on the valve face
- Poor emission test results

Important Fitment Notes:
- HDA-008 / MC828264 are aftermarket cross-reference numbers that appear primarily in Mitsubishi Fuso brake booster catalogs. This product is primarily intended for 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. Both "short" and "long" pushrod variants exist within the MC828264 family.
- Always provide the VIN or chassis number for verification. Do not rely solely on cross-reference numbers.

| Stem diameter | Micrometer against OEM spec Pending |
| Head diameter | Caliper against OEM spec Pending |
| Overall length | Height gauge against OEM spec Pending |
| Valve face angle | Optical comparator or angle gauge Pending |
| Material hardness | Rockwell hardness test Pending — recommend establishing an internal standard |
| Surface finish / coating | Visual inspection, oxidation resistance check |
Important: Cylinder head removal and valve replacement require specialized engine workshop equipment. Exhaust valve seating and stem clearance must be verified before installation. Professional installation is strongly recommended.
- Remove the cylinder head per the workshop manual. Disassemble the valve train.
- Clean the valve guides and seats. Check guide wear and replace if clearance exceeds the OEM limit.
- Check valve seat width and concentricity. Re-cut or replace seats as needed.
- Install the new exhaust valve. Check stem-to-guide clearance.
- Lap the valve to the seat if required. Verify sealing with marking compound.
- Install valve springs, retainers, and keepers per OEM procedure.
- Adjust valve clearance to OEM specification: Exhaust 0.35 mm cold.
Inspect valve clearance every 40,000–60,000 km (verify against the JAC maintenance schedule). Replace valves when clearance can no longer be adjusted, or when compression loss, exhaust noise, or emission failure indicates wear.
- Neutral carton or customized packaging available
- Suitable for wholesale distributors, engine repair workshops, and JAC parts suppliers
- MOQ negotiable; samples available for quality verification
