Crankshaft Timing Sprocket1021002F0016 – Product Introduction

The 1021002F0016 crankshaft timing sprocket is a real workhorse in the Dongfeng Dignity IX5’s engine timing system—think of it as the “节拍器” that makes sure all the key engine parts move in perfect step. It’s not some basic metal gear, either—it’s made just for the Dignity IX5’s engine setup (usually pairing with its 1.5T engines, like the SFG15T series) and has a super critical job: keeping the engine running smooth, efficient, and safe.

Main Job: Keeping the Engine in Sync

Every engine needs its parts to move with exact timing—otherwise, stuff like pistons and valves could slam into each other (total engine chaos!). That’s where this crankshaft timing sprocket steps in:

It bolts right onto the end of the engine’s crankshaft (that’s the part that turns the up-and-down motion of the pistons into the spinning power that moves the car).

It teams up with the timing chain (or belt, depending on how the engine’s set up) and the camshaft timing sprocket to pass power from the crankshaft over to the camshaft.

Design Breakdown: Made to Fit Perfectly & Work Precisely

• Tooth Design: It has teeth that are evenly spaced and sharp—usually straight, or sometimes slightly angled “helical teeth”—that grip the timing chain super tight. The number of teeth and their shape? They’re adjusted just right for the Dignity IX5’s timing system. If there were too many, too few, or the shape was off, it’d mess up the whole timing.
• Center Mounting Hole: The hole in the middle is drilled super precisely, so it fits the end of the Dignity IX5’s crankshaft tight—no wiggling at all. There’s also a little keyway in there, just a small slot, that lines up with a tiny tab on the crankshaft. This keeps the sprocket from sliding around or spinning on its own, separate from the crankshaft.
• Lightweight but Sturdy Shape: It might have lightening holes—small little cutouts—around the edges. These cut down on extra weight (which helps the engine work better) without making the sprocket weaker. The outer edge is polished too, so it doesn’t wear out the timing chain over time.

Material Lowdown: Tough Enough for Daily Beatings

• Wear Resistance: The teeth rub against the timing chain thousands of times every minute. So the material is hardened (usually by heat-treating it) to make sure it doesn’t wear out fast.

• Fatigue Resistance: It has to handle repeated twisting force and shaking from the crankshaft. The alloy steel can deal with that for years without cracking or bending.

To sum it up, the 1021002F0016 crankshaft timing sprocket is basically the Dignity IX5 engine’s “timing cop”—it makes sure all the parts move together nice and smooth. Its precise design, tough materials, and that fit that’s only for this specific model? They aren’t just little extras that don’t matter—they’re exactly what keeps the engine running reliably, no matter how many miles you put on it.
