Door Gas Strut (340mm) suitable for JCB 3CX 4CX (<1997) - 123/05403

Technical Specification and Compatibility

Precisely calibrated 123/05403 gas spring (strut) by GX-AFTER. This component is responsible for assisting the opening and holding open the operator's cab door. Dedicated to older generations of JCB 3CX and 4CX backhoe loaders (models produced before 1997, e.g., Project 8 / Grey Cab). The strut features a specific total length of 340 mm, distinguishing it from newer versions.

Part Number: 123/05403
Alternative Numbers: 122/67484, 123/04798
Type: Door Gas Strut
Total Length: 340 mm
Cylinder Length: 197 mm
Application: Older machines (pre-1997)

GX-AFTER is synonymous with reliability in the spare parts segment. Our gas struts are nitrogen-filled under strictly controlled pressure, ensuring smooth operation and maintenance of nominal lifting force over a long service life.

Features of GX-AFTER 123/05403 Strut

Corrosion Protection: Powder-coated cylinder and chrome-plated piston rod provide resistance to moisture and changing weather conditions.
Dedicated Geometry: The shorter dimension (340mm) perfectly fits the hinge kinematics of older JCB cabs, where newer, longer struts do not fit.
Durable Seals: Multi-lip sealing package prevents gas escape and damping oil leakage.
Stable Force: Precisely selected force (Newtons) allows for easy door opening and secure holding in the open position.

Application in JCB machinery

Machine Type Models / Years
Backhoe Loaders 3CX, 4CX (manufactured before 1997)
Cab Type Older type cabs (Grey Cab / Project 8)

Note: Machines after 1997 (Project 12/21) usually use longer struts. Please measure the old part.

Related Parts and Hardware

The strut is typically mounted on ball joints. If the mounting sockets on your machine are worn, we recommend replacing them to ensure smooth operation of the new telescope.

⚠️ Safety Warning

A worn gas strut may not hold the heavy machine door, causing it to fall suddenly and uncontrollably. This poses a risk of trapping the operator's limbs. Replace struts in pairs as soon as you notice a drop in holding force.

Part Role in the Machine and Failure Diagnostics

The gas telescope compensates for the weight of the door, making it easier to open and preventing it from closing automatically (e.g., in the wind).

  • › Door sagging (loss of gas pressure).
  • › Oil leak from the cylinder (seal damage).
  • › Jerky operation or jamming (bent piston rod).
  • › Piston rod corrosion (causing leaks).

🔧 Expert Guide: Key Installation Tips

  1. Control Measurement: Before purchasing, measure the old strut (fully extended). It must be approx. 340 mm. If it is approx. 390-400 mm, you need a different part (for newer machines).
  2. Orientation: Mount gas struts with the piston rod (thinner part) pointing downwards when closed to ensure the seal is lubricated by the internal oil.
  3. Safety: Do not attempt to compress the new strut by hand before installation – it requires high force, which is only provided by the door leverage.

Frequently Asked Questions (FAQ)

Does it fit a 2005 machine?

No. Machines from 2001-2012 (P21 cab) typically require a longer strut (approx. 390 mm, part no. 128/13052). This model (340 mm) is for older versions.

Is the force adjustable?

No. Gas struts have a factory-set force (in Newtons), selected for the weight of the specific machine's door.

What are the cylinder dimensions?

The length of the body (thicker part) is about 197 mm, and the total extended length is 340 mm.
