Connecting Rod Tile – Precision Engine Bearing for Enhanced Engine Performance

The 1004002F0000 connecting rod tile (commonly referred to as a connecting rod bearing in automotive terminology) is a critical engine component exclusively engineered for the Dongfeng Dignity IX5 model. As a core part of the engine’s power transfer system, it plays an irreplaceable role in ensuring smooth operation, load resistance, and long-term reliability—especially tailored to the performance characteristics of the Dongfeng Dignity IX5’s powertrain.

Core Position & Functional Role

Connecting rod tiles are mounted in the "big end" of the engine’s connecting rod, forming a precision interface between the connecting rod and the crankshaft journal . Its primary functions include two key aspects:

Power Transmission: It converts the reciprocating motion of the pistons (driven by fuel combustion) into the rotational motion of the crankshaft—directly enabling the vehicle’s drive force. During this process, it must withstand cyclic loads exceeding thousands of Newtons generated by combustion pressure .

Friction Reduction & Protection: By maintaining a stable oil film between metal surfaces, it eliminates direct contact between the connecting rod and crankshaft, minimizing wear and heat generation. This is critical for preventing catastrophic engine failure caused by metal-to-metal friction .

Structural Design & Material Traits

We’re talking top-tier precision here for the 1004002F0000 connecting rod tile—it uses a split-sleeve design, just two half-circle pieces. That makes installation a total breeze, and it also keeps the tile snug against the crankshaft journal, no loose fits. And the materials? They’re totally tuned to what the Dongfeng Dignity IX5’s engine needs:

Base Layer: It’s got a tough backing made of high-strength carbon steel or alloy steel. This part gives the tile the sturdiness to handle those super heavy mechanical pressures—its yield strength usually sits between 370 and 490 MPa, so it doesn’t bend or break easily.

Wear Layer: There’s a thin coat on top, either aluminum-based alloy or copper-lead alloy. We pick these materials ’cause they’re awesome at resisting wear and rust. Plus, they have “conformability”—fancy way of saying they can fit right into those tiny uneven spots on the crankshaft. And this coat is machined super precisely—tolerances are down to the micrometer level. That way, it clicks perfectly with all the Dignity IX5’s engine parts.

Lubrication Setup: On the inside of the tile, there are built-in oil grooves. These grooves keep engine oil flowing steady, so the oil film (that’s what stops metal-on-metal friction) stays put even when the engine’s revving high—right up to the Dignity IX5’s usual RPM range.

Fit for the Dignity IX5 (And Only It!)

The 1004002F0000 connecting rod tile is only made to work with the Dongfeng Dignity IX5’s engine. Yeah, the Dignity IX5 shares some tech with Dongfeng’s 1.5T engine family—like the SFG15T 1.5T engine you’ll find in the Dongfeng Fengguang IX5—but here’s the thing: connecting rod tiles don’t work across different models. This one’s custom for the Dignity IX5, and here’s why that matters:

The size is tailor-made. It fits exactly with the Dignity IX5’s crankshaft journal diameter and the big end hole of the connecting rod—no “close enough” here.

Its weight-bearing ability is tuned to match the engine’s max torque. So even when the engine’s working hard—like when you’re speeding up or climbing a hill—it stays stable, no slipping or giving out.

It plays nice with the car’s original lubrication system. No weird issues where the oil film breaks apart or oil starts leaking—everything works like it should.

When to Replace It

Watch for these red flags—they’re signs the tile might be worn or damaged:

• Your engine starts knocking, especially when you’re putting it under load (like accelerating hard).

• You’re going through oil faster than usual.

• There are little metal bits floating around in your oil.

What You Need to Know When Installing

• Stick with the original Dongfeng end cap bolts. And make sure you tighten them exactly to the specs the factory recommends. If you don’t, you could end up with uneven pressure, which causes problems.

• The two half-circle pieces can switch places—no biggie. But here’s the key: line up their oil grooves with the oil passages in the connecting rod. If they’re not aligned, the oil can’t flow right.Why Sticking with the Real Deal Matters
