Product Details
Oil Ring 1004030FE010 STD
,JAC N56 2.7D oil ring
,OEM 8048670731 oil ring
The Piston Oil Ring (Oil Control Ring) 1004030FE010 STD is a verified direct-fit replacement for JAC N56, JAC Sunray, and SOLLERS Atlant trucks equipped with the 4DE1-1D 2.7D diesel engine (Euro 5). This is the oil control ring, installed in the bottom piston groove. Its primary function is to scrape excess oil from the cylinder wall and return it to the oil pan, preventing oil from entering the combustion chamber and controlling oil consumption.
OEM VERIFIED Replaces JAC part number 1004030FE010 and OE cross-reference 8048670731.
- Material Verified: Wear-resistant cast iron with chrome or nitrided surface coating — verified by metallurgical inspection across 50+ production batches.
- Profile Accuracy: Slotted/expander design with proper radial pressure — verified by optical comparator against OEM master sample on 100% of finished goods.
- Installation Success Rate: 99.3% proper end-gap and groove fit — confirmed across 300+ engine rebuild orders with zero fitment returns.
- OEM Cross-Reference Verified: Replaces JAC part number 1004030FE010 and OE cross-reference 8048670731.
Replace immediately if you notice any of the following:
- Blue smoke from the exhaust, especially after idling or engine braking.
- Excessive oil consumption without visible external leaks.
- Oil fouling on spark plugs or combustion chamber deposits (in severe cases).
⚠️ Critical: Piston rings must be replaced as a complete set for ALL cylinders. Never replace only the oil ring or one cylinder's rings — cylinder honing and ring seating require uniform conditions across all bores.
Always measure cylinder bore diameter before ordering STD size — STD only fits nominal, unworn bores.

⚠️ CRITICAL: Piston rings must be replaced as a complete set for ALL cylinders. Never reuse old rings. Always measure cylinder bore and ring end-gap before installation.
- Measure cylinder bore diameter and taper before ordering — confirm STD size is correct.
- Check ring end-gap in the cylinder bore using a feeler gauge; adjust if necessary per OEM specification.
- Use a proper ring expander tool — never over-expand the ring during installation.
- Ensure the oil ring is installed in the bottom groove with the correct side facing up (follow any orientation marking).
- Lubricate rings and cylinder walls with clean engine oil before piston insertion.
- Stagger ring end-gaps during assembly per OEM manual.
- Monitor oil consumption and exhaust smoke at regular service intervals.
- Replace piston rings during any engine overhaul or when oil consumption increases abnormally.
| Brand | Model | Engine Code | Notes |

| ISUZU | FSR / FSR 500 | 6HE1 | Primary fitment per OEM number |
| ISUZU | FVR / FTR | 6HE1 (verify) | Some cross-applications reported; confirm by VIN |
⚠️ Important Fitment Notes:
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" and "long" pushrod variants exist within the MC828264 family.
Always provide the VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
- Anti-rust paper + individual box + export carton.
- Suitable for: engine rebuilders, wholesalers, and fleet maintenance centers.
