Metal Fuel Filler Cap (90mm) suitable for JCB 3CX 4CX (Pre-1997) - 122/62400

Technical Specification and Compatibility

Robust 122/62400 fuel filler cap from the GX-AFTER offer. It is a large diameter (90 mm) metal cap, dedicated to older generations of JCB machines, produced mainly before 1997. It is used in 3CX/4CX backhoe loaders (grey cabs, Project 7), Loadall telehandlers, and older models of skid steers, forklifts, and wheel loaders.

Part Number: 122/62400
Component Type: Fuel Cap
Outer Diameter: 90 mm
Closure Type: Bayonet (Twist-lock)
Material: Metal + Rubber Gasket
Year Application: Mainly pre-1997
Manufacturer: GX-AFTER

The GX-AFTER cap is a faithful copy of the original metal part that was installed in classic JCB machines. Durable construction and a thick gasket ensure tank tightness, preventing fuel leaks and contamination ingress.

Features of GX-AFTER 122/62400 Cap

Metal Construction: Resistant to impact, cracks, and fuel, which is crucial in older machines operated in difficult conditions.

Related Parts and Hardware

The cap is supplied with a set of keys. In case of fuel system problems in older machines, it is also worth checking the condition of the fuel filler strainer and replacing the fuel filter.

⚠️ Safety Warning

Driving without a cap or with a leaking cap risks fuel spillage, creating a fire hazard and environmental contamination. Additionally, water and dirt can enter the tank, which can damage the injection pump.

Part Role in the Machine and Failure Diagnostics

Cap 122/62400 closes the fuel tank.

  • › Fuel leak (perished cap gasket).

🔧 Expert Guide: Key Installation Tips

  1. Dimension: Measure the diameter of the old cap. This one is approx. 90 mm. If your cap is smaller (approx. 60 mm) and plastic, you need a different model (for newer machines).
  2. Lock: Lubricate the cap lock regularly (e.g., with WD-40 or silicone grease), especially in winter, to avoid freezing and breaking the key.
  3. Breather: Ensure the breather in the cap is patent. A clogged breather can cause vacuum in the tank and engine operation problems.

Technical FAQ and Trivia

Does it fit a plastic tank?

Usually not. Plastic tanks (installed in newer JCBs) have smaller, screw-in caps with threads. This cap is a bayonet type ("push and twist") for metal fillers.

Are the keys universal?

JCB caps usually have a universal key pattern for a given cap series, but they do not always fit the ignition or door (which often use the 701/45501 key).

Historical Trivia

Caps with a diameter of 90 mm were standard in the "golden era" of construction machinery of the 80s and 90s. Their large diameter facilitated refueling from jerry cans on the construction site, which was commonplace at that time.
