Dongfeng
| Attribute | Specification |
|---|---|
| Product Name | Connecting Rod (Engine) |
| Manufacturer | Cummins Inc. (OEM) |
| Part Number (Primary) | 3942579 |
| Material | High-strength alloy steel, forged and heat-treated |
| Construction Type | Forged, full-floating design |
| Big End Design | Plain-cut (Flat-cut), paired with matching cap |
| Small End Feature | Press-fit bronze bushing for piston pin articulation |
| Surface Treatment | Shot-peened and precision-machined for fatigue resistance |
| Weight Matching | Factory weight-classified; minimal weight variance within set |
| Application Type | Internal combustion engine – Reciprocating motion linkage |
| Position in Engine | Between piston pin and crankshaft journal |
| Quality Standard | Meets or exceeds Cummins OE specifications |
| Parameter | Value / Detail |
|---|---|
| Engine Platform Compatibility | Cummins B-Series: 6BT 5.9L, 4BT 3.9L, ISB/QSB 5.9L (early models) |
| Typical Length (Center-to-Center) | Approx. 7.559 inches (192 mm) – typical for 5.9L rods |
| Big End Bore Diameter | ~2.283 in (58.0 mm) – accepts standard crankshaft rod journals |
| Small End Bushing ID | ~1.181 in (30 mm) – compatible with standard piston pins |
| Bearing Clearance Tolerance | 0.0008–0.0015 in (20–38 μm), per 2025 service manual standards |
| Tensile Strength | ≥ 1200 MPa (after heat treatment) |
| Fatigue Resistance | Optimized for high-cycle loading under sustained high boost and EGT |
| Dynamic Balance | Precision-weighted for multi-cylinder balance; strict inter-rod mass tolerance (< ±5g recommended) |
| Load Capacity | Designed to withstand peak cylinder pressures > 200 bar (typical for turbocharged diesel operation) |
