Chery FX Air Valve Shaft VVT Gear (Part No.: F4J161006030BA)

First of all, let's keep it simple: The Chery FX valve shaft VVT gear F4J161006030BA is not merely a "metal gear" - it is the "valve timing tuner" of your FX engine. It can be imagined as an intelligent connection between the engine camshaft and the valve shaft, which adjusts when the engine valves open or close (referred to as "variable valve timing" or VVT). This adjustment makes your FX more powerful when you accelerate and more fuel-efficient when you cruise, while keeping the engine running smoothly. Without it, your foreign exchange will feel sluggish, consume more gasoline, and there is even a risk of engine fire.

This component is only applicable to Chery FX models with F4J16 engines (please be sure to check the vehicle's VIN or user manual for confirmation!) Its design is intended to perfectly match the engine compartment of the FX: the teeth of the gears are precisely aligned with the camshafts and valve shafts (without any sloppy fit), the VVT oil ports are precisely controlled with the engine's oil system, and the length/shape of the shafts is matched with the cylinder head of the FX - no modification is required. Buy an ordinary one? You will encounter headache-inducing problems: misaligned teeth (disrupting valve timing), oil port leakage (losing pressure), or weak metal (wearing out quickly) - this is a disaster for the components that keep the engine "breathing" normally.

1. Core Work: Why does this part make your foreign exchange drive better

Don't underestimate its role - it has three key functions for your FX engine:

The power of regulating valve timing: When you step on the accelerator (for example, onto a highway), the VVT gears adjust the valve timing to allow more air/fuel to enter the engine. This boosts horsepower and enables your FX to accelerate faster.

Save fuel for cruising: When you are traveling at a stable speed (for example, on a highway), it will adjust the time to reduce unnecessary air/fuel usage. This reduces the consumption of gasoline - when you don't need extra power, you won't waste fuel anymore.

Keep the valves synchronized: The valve shaft itself transmits the movement of the VVT gears to the engine valves. It ensures that all valves open/close at the right moment, preventing misignition (when fuel burns at the wrong time) and engine damage.

This F4J161006030BA component is only applicable to the F4J16 engine of Chery FX. Using it wrongly will ruin your engine.

Suitable for these models: Chery FX (F4J16 engine model; confirm through VIN to match your engine code).

Not suitable for these

Other Chery models (such as Tiger 8, Rui 7) : Their engines (such as 1.6T GDI) use different VVT gears/shafts, and this part will not align.

Non-chery cars: Even if it "looks very similar", the gear size, shaft length and oil port are all wrong - installing it will cause valve damage.

Engine compatibility: Engineering with FX's original camshaft, valve mechanism, and oil system. Camshafts in the aftermarket may require matching VVT components - stick to factory parts.

Installation and Maintenance (For professionals only - Engine timing is crucial!)

Installation: Left to Chery Experts

This is not a DIY job - mistakes here can damage your engine. The following is what professionals do:

Lock the engine timing: They use special tools to secure the camshaft/valve shaft in place (so the timing does not shift during gear shifting).

Replacement of parts: Disassemble the old gears/shafts, clean the oil ports, and install f4j161006030ba - ensure perfect gear meshing and oil port alignment.

Test pressure: They checked the oil pressure of the VVT gears (to ensure it was adjusted correctly) and took a test drive to confirm there was no misfire or power lag.

Maintenance: Keep it working properly

Timely oil change: The VVT system relies on clean oil - dirty oil clogs the control ports (resulting in slow adjustment). Persist in using the engine oil type recommended by Chery and change the oil every 5,000 to 7,500 kilometers.

Listen carefully: If you hear a ticking sound from the engine (especially when accelerating), it might indicate that the gears are worn out - go and check it out right away.

Check for leaks: If there is engine oil near the cylinder head, it indicates that the sealing ring may be faulty. Please replace the sealing ring to prevent damage to the VVT system.
