Product Details
Second Compression Piston Ring JAC N56
,OEM STD Piston Ring 4DE1-1D
,Piston Ring SOLLERS Atlant 2.7D
The Second Compression Piston Ring with OEM number 1004026FE010 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 second (lower) compression ring, installed in the second piston groove from the top. It provides secondary combustion sealing, works in tandem with the top ring to control blow-by, and assists the oil control ring in managing oil consumption.
- Material Verified: Wear-resistant cast iron with protective coating (phosphate or chrome) — verified by metallurgical inspection across 50+ production batches.
- Profile Accuracy: Taper-faced or barrel-shaped working surface with scraper edge — 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: Exactly replaces JAC part number 1004026FE010, standard size (STD, d=0.00).
- Blow-by (excessive crankcase pressure causing oil leaks from seals).
- Increased oil consumption without visible external leaks.
- Blue smoke from exhaust under acceleration.

- 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.
| QC Item | Verification Method |
|---|---|
| Ring Diameter | Micrometer measurement against OEM specification |
| Radial Thickness | Precision measurement (±0.01 mm tolerance) |
| Surface Coating Thickness | Coating thickness gauge |
| End Gap | Feeler gauge check (pre-set to OEM specification) |
| Profile Shape | Optical comparator comparison with OEM master |
| Material Hardness | Hardness tester (meets OEM material standard) |
- 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 ring is installed with the correct side facing up (follow any orientation marking, typically "TOP" or a dot).
- Lubricate rings and cylinder walls with clean engine oil before piston insertion.
- Stagger ring end-gaps during assembly per OEM manual.
- Inspect compression and oil consumption at regular service intervals.
- Replace piston rings during any engine overhaul or when compression drops below specification.
- Anti-rust paper + individual box + export carton.
- Suitable for: engine rebuilders, wholesalers, and fleet maintenance centers.
