A high-quality torque converter, a key component of the drivetrain in machines with a gearbox. Its function is to smoothly transfer torque from the engine to the gearbox, allowing for smooth starts and load changes without jerking. Precision balancing and durable construction guarantee quiet operation and maximum service life.
In the construction industry, machine reliability is the key to success. That's why we offer high-quality replacement parts for construction machinery that meet the highest standards of durability and performance. Our products are the ideal solution for companies and specialists looking for reliable components at attractive prices.
The dots on the converter are a color code for the quick identification of the key parameter: its stall ratio. This is a visual shortcut for mechanics – instead of searching for a stamped part number on a dirty component, you can identify the converter type at a glance. For this product, the combination of Orange/Yellow/Orange uniquely identifies a converter with a 2.52:1 stall ratio.
Imagine it's like the "first gear" in a car – it determines how much power the machine has when starting off. Technically, the stall ratio is the maximum torque multiplication a converter can achieve when the engine is revving but the machine is stationary. A higher ratio means more pushing power. Installing a converter with the wrong ratio will make the machine feel "weak" or inefficient. This is why correct identification is crucial.
The color code should be distinguished from single balancing marks (e.g., drill holes), which ensure vibration-free operation.
| Brand (Machine Type) | Model |
|---|---|
| JCB (Backhoe Loaders) | 3CX, 4CX |
| JCB (Telehandlers) | Loadall |
The list above is for reference. Before purchasing, we recommend verifying the part number or color code on your machine.
Replacing a torque converter requires splitting the engine from the transmission. This is a complex and dangerous operation requiring specialist tools and knowledge. Always follow the manufacturer's service manual and secure the machine against rolling.
The torque converter is a key component of the drivetrain. Its failure leads to a loss of power, driving problems, and can result in damage to the oil pump or the entire gearbox due to circulating metal filings.
A damaged torque converter risks destroying the entire transmission.
Shrapnel from a disintegrating converter will destroy the oil pump, solenoids, and clutch plates. The cost of a new converter is negligible compared to a full transmission rebuild. Don't take the risk – order a proven NEXGEN torque converter and restore full power and a smooth drive to your machine.

A torque converter is a type of fluid coupling that transfers power from the engine to the transmission via hydraulic fluid. It consists of an impeller, a turbine, and a stator. There is no mechanical connection, which allows for smooth starts and load changes without jerking.
2. What does the "stall ratio" (e.g., 2.52:1) mean?The stall ratio defines the ratio of the input speed (from the engine) to the output speed (to the gearbox) when the turbine is stalled. A value of 2.52:1 means the converter can multiply the torque by over 2.5 times when starting from a standstill, which is crucial for construction machinery. Choosing a converter with the correct ratio is essential for the machine's proper performance.
3. The machine is weak and struggles to drive. Is it definitely the converter's fault?It is a very common cause. However, before deciding to replace it, you should check the oil pressure in the transmission. Low pressure, caused for example by a worn oil pump or leaks, will also manifest as a lack of power.
4. Can an old torque converter be refurbished?Yes, there are companies that specialize in refurbishment, but it is a complex process that requires cutting the unit open, replacing internal components, and precision balancing. Due to the critical role of this component, buying a new, proven part is often a more reliable and cost-effective solution in the long run.
