TORQUE CONVERTER (2.52 RATIO) SUITABLE FOR JCB 3CX, 4CX - 04/600784

Technical Specification and Compatibility

An essential component of the drive system – a torque converter, designed for JCB machines with Powershift transmissions. It is a key component that transfers torque from the engine to the transmission via hydraulic fluid, enabling smooth starts and gear changes under load. A faulty converter leads to loss of drive, oil overheating, and can damage the transmission oil pump.

Part's Role in the Machine and Failure Diagnostics

The torque converter is a key component of the Powershift transmission. Its failure leads to serious drive problems, and filings from a damaged converter can destroy the entire gearbox.

  • › Loss of drive or "weak drive", especially when the oil is hot.
  • › Overheating of the transmission oil.
  • › Unusual, loud noises (whining, grinding) coming from the gearbox.
  • › Presence of a large amount of metal filings in the transmission filter and oil.

Peace of Mind Guarantee: Why Choose Our Offer?

A failed converter is a direct path to a destroyed gearbox.

Filings from a damaged torque converter act like sandpaper on the precision components of the gearbox. The cost of replacing the converter is negligible compared to a general overhaul of the transmission. Don't take risks – order a new, reliable torque converter and protect your investment.

Frequently Asked Questions (FAQ)

1. How to Decode the Markings on the Converter? ⚙️

The dots on the converter are a color code used for quick identification of the converter's key parameter: its stall ratio. It's a visual shortcut for mechanics. Common combinations (JCB 3CX/4CX and related) are:
- 2x Purple + 1x White: Ratio 2.20:1 (e.g., 04/500100)
- 2x Orange + 1x Green: Ratio 2.44:1 (e.g., 04/500800)
- Orange + Yellow + Orange: Ratio 2.52:1 (e.g., 04/600650)
- Purple + Yellow + Purple: Ratio 2.82:1 (e.g., 04/501400)
This color code should be distinguished from single balance markings (e.g., drill marks), which ensure vibration-free operation.

2. What is "Stall Ratio" and Why is it Important?

Imagine it as the "first gear" in a car – it determines how much power the machine has "off the line." Technically, the stall ratio is the maximum torque multiplication the converter can achieve when the engine is revving, but the machine is stationary. A higher ratio means more pushing power when starting. Installing a converter with the wrong ratio will make the machine feel "weak" or inefficient. That's why correct identification is so important.

3. The machine has no power to drive. Is it definitely the converter's fault?

Loss of drive, especially when hot, very often indicates a damaged torque converter (e.g., worn blades or internal seals). Other causes include low performance of the transmission pump, leaks in the clutch packs, or a clogged transmission oil filter.
