Dongfeng Gearbox Parts are widely compatible with multiple flagship vehicle series, including the Chenglong H5/HK, Huasheng HV3/HV5/HV7, and the premium tractor models Tianlong GX and Tianlong KX King Edition.
Dongfeng ensures the highest standards of protection and integrity for its gearbox components through rigorously tested packaging solutions. Each part is meticulously packaged to withstand global logistics challenges, utilizing two primary methods tailored to the product’s size, peso, y fragilidad:
Ideal for smaller to medium-sized components like shift levers, válvulas, and synchronizer rings, these boxes are crafted from high-strength, export-grade corrugated paper. Features include:
Reserved for heavy or high-value assemblies such as complete gearbox casings, planetary carriers, and first shafts, these crates are engineered for maximum durability:
Dongfeng gearbox parts are shipped globally via diversified logistics solutions to meet urgent demands and cost efficiency. Four primary methods are deployed:

Use Dongfeng-specified **genuine transmission fluid (p.ej., DF-6)**. Different transmission models have strict requirements for fluid viscosity and grade. Replace the fluid and filter every **50,000–80,000 kilometers** or as specified in the Owner’s Manual.
With the vehicle level, check the dipstick to ensure the oil level is within the “HOT” range. Simultaneously observe the oil color, which should be clear red or amber. If it appears black, cloudy, or emits a burnt odor, **replace immediately**.
Check the oil level only after the transmission has reached normal operating temperature. Sin embargo, after long-distance or heavy-load driving, it is recommended to **idle for a few minutes** before checking to avoid burns and ensure accurate readings.
Regularly remove dirt and oil residue from the transmission housing, especially the **radiator grille**. This ensures efficient cooling and prevents oil oxidation and premature component wear caused by excessive oil temperatures (typically >120° C).
When changing fluid, **always replace the filter** (including both the internal screen and external cartridge). Substandard filters provide poor filtration, being a primary cause of valve body clogging and lubrication failure.
Ensure complete clutch disengagement before shifting; avoid **impact loads** like sudden throttle application, abrupt acceleration, or rapid deceleration to prevent gear, Llevando, and synchronizer overload damage.
Immediately stop and inspect if you notice **shifting difficulties, unusual noises (p.ej., knocking sounds), vibraciones, or oil leaks**. Continuing to drive may worsen the fault and increase repair costs.
The transmission is a precision assembly. Disassembly, clearance adjustments, and calibration of electronic control units (p.ej., AMT models) must be carried out by **trained technicians at authorized service centers** using specialized tools to prevent improper repairs.
Check for **aging or cracking transmission mounts** and **loose driveshaft connection bolts**. Issues with these components can cause transmission misalignment or excessive stress, leading to damage.
In cold climates, allow the engine to idle for several minutes after starting to raise oil temperature. Only drive once fluid viscosity has restored to prevent dry friction. In extreme cold, switch to transmission fluid suitable for low temperatures.
**UN:** Genuine Dongfeng parts feature a unique anti-counterfeiting label with a QR code. Scan it using the official Dongfeng Parts verification app or WeChat mini-program to instantly check authenticity, número de pieza, and production date.
**UN:** Most Dongfeng gearbox parts come with a standard warranty of **12 months or 100,000 kilometers** (lo que sea que venga primero). Warranty terms are clearly stated on the invoice and require proper installation at an authorized service point.
**UN:** Grinding noises often point to worn **synchronizer rings** or damaged **gearb teeth**. We recommend stopping operation and having a professional diagnose the issue to prevent further damage to the gearbox assembly.
**UN:** While some parts might be physically compatible, we **strongly recommend against it**. Dongfeng parts are engineered to precise specifications for Dongfeng gearboxes. Using them in other brands can lead to performance issues, premature failure, and will void the warranty.
**UN:** We offer flexible payment options including **T/T (Bank Transfer)**, **carta de crédito (Carta de crédito)** for large orders, and secure online payments via Alibaba Trade Assurance for your convenience and transaction security.
**UN:** Sí. We provide detailed installation manuals (PDF/paper) for complex components like complete gear sets. Además, our technical team is available via WhatsApp or email to provide guidance for professional mechanics.
**UN:** Lead time depends on the shipping method:
* **Flete aéreo:** 5-10 días (ideal for urgent, smaller orders).
* **Sea Shipping:** 30-45 días (cost-effective for large volumes and full containers).
A precise timeline will be confirmed after order placement.
**UN:** MOQ varies by part. For common replacement parts (p.ej., focas, aspectos), MOQ can be as low as **10 pieces**. For larger assemblies, **1 piece** is often acceptable. We offer competitive pricing for bulk purchases.
**UN:** The two most critical maintenance tasks are:
1. **Regular Oil Changes:** Use only recommended lubricants (p.ej., API GL-4 or GL-5) and change the oil and filter at intervals specified in your vehicle’s manual (típicamente cada 50,000 – 80,000 kilómetros).
2. **Check for Leaks:** Regularly inspect for oil leaks around seals and gaskets and address them promptly.
**UN:** The safest way is to provide us with your truck’s **VIN (Número de identificación del vehículo)**. Alternativamente, you can provide the exact **gearbox model number** (p.ej., DF14S1650) and the truck’s model (p.ej., Dongfeng KL). Our specialists will cross-reference it to ensure you get the perfect match.
