GENUINE JCB FUEL CAP (IGNITION KEY) - 123/05892

Technical Specification and Compatibility

An original, locking fuel tank cap designed for a wide range of JCB machines. Its key feature is compatibility with the genuine JCB ignition and door key. This eliminates the need to carry extra keys. Made from durable, fuel-resistant polymer with a metal locking mechanism, it provides a tight and secure seal for the fuel tank, protecting against theft and contamination.

Alternative part numbers: 331/45908, 331/33064
Manufacturer: JCB (Genuine)

Genuine JCB product – a guarantee of the highest quality, perfect fit, and 100% compatibility with your machine.

Worth Checking During Replacement

  • › Cap Gasket/O-ring: Check if the old gasket is perished (new cap includes a new one).
  • › Fuel Filler Strainer: Ensure the strainer inside the filler neck is not damaged or clogged.

Application in machines

Brand Type / Series / Model
JCB Backhoe Loaders: 2CX, 3CX, 4CX, MIDI CX
Telehandlers (Loadall)
Wheel Loaders
Rough Terrain Forklifts (RTFL)
Dumpers
Mini Excavators: MICRO

The list above is for reference. This cap fits the majority of JCB machines. The key is to verify visually and confirm the key type (genuine JCB).

⚠️ Warning

Always ensure the fuel cap is tightly closed and locked. An unsecured tank risks fuel theft and contamination (water, dirt), which can lead to catastrophic failure of the injection pump and injectors.

Part's Role in the Machine and Failure Diagnostics

The fuel cap secures the filler neck from theft and contamination (water, dust). It must also properly vent the tank to prevent a vacuum from forming.

  • › Damaged or jamming lock mechanism.
  • › Lost key (in case of non-genuine caps).
  • › Leaking or perished gasket (allowing fuel out or water in).
  • › Cracks in the cap body.

🔧 Expert's Guide: Key Installation Tips

  1. One Key Fits All: The biggest advantage of this genuine cap is convenience. You use the same key that opens your door and starts the engine.
  2. Lock Maintenance: Regularly lubricate the lock mechanism (e.g., with graphite spray) to prevent it from jamming, especially in winter or dusty conditions.
  3. Gasket Inspection: Visually check the cap's gasket every time you refuel. A perished or cracked gasket is the main cause of water ingress into the tank.

Frequently Asked Questions (FAQ)

1. Will this cap fit my aftermarket (non-original) ignition key?

No. This cap is designed to work exclusively with the genuine JCB master key system. If your machine has an aftermarket ignition switch with a different key pattern, this cap will not match.

2. My old cap is 331/45908. Will this fit?

Yes, the part numbers 123/05892, 331/45908, and 331/33064 are used interchangeably by JCB and refer to the same genuine fuel cap that uses the ignition key.

3. Is this cap vented?

Yes, genuine JCB fuel caps are designed to properly vent the tank, which prevents a vacuum from forming as fuel is consumed.
