Application in machines

Brand (Machine Type) Model
JCB (Backhoe Loaders) 3CX, 4CX (older models with rack and pinion slew)

The list above is for reference. Before purchasing, please ensure your machine has a rack and pinion slew mechanism and a 110mm diameter cylinder.

Service Recommendation: Ensure Maximum Lifespan

The cleanliness of the hydraulic system is key to the long life of seals. Before installing the new kit, we recommend replacing the hydraulic filter with a new REDX filter. Use only high-quality hydraulic oil, such as HYPTRON, to ensure optimal lubrication and protection for the new seals.

Part's Role in the Machine and Failure Diagnostics

The slew rams are the "muscles" of the backhoe arm, allowing it to move precisely from side to side. The seals inside these rams maintain the hydraulic oil pressure that is necessary to generate force. Their wear leads to internal and external leaks, causing a loss of precision and power.

Replace the seals if you notice any of the following symptoms:

  • Visible oil leaks from the slew rams, especially around the piston rod.
  • "Drifting" or spontaneous movement of the backhoe arm to the side during work or when stationary.
  • Lack of power or slowed slewing, especially under load.
  • Jerky, non-smooth slewing motion of the backhoe arm.

Peace of Mind Guarantee: Why Choose Our Offer?

Leaking rams mean a loss of power, time, and money. The GX-AFTER seal kit is a smart choice that allows for an independent and inexpensive cylinder rebuild. Made from high-quality materials, it restores factory tightness and control precision, eliminating the frustrating "drifting" of the arm.

Our repair kit is available off-the-shelf. **Order now, eliminate leaks, and restore full power and precision to your machine!**

Expert's Guide: Key Installation Tips

  1. Maintain perfect cleanliness: The smallest grain of sand can damage new seals. Work in a clean environment and thoroughly clean all cylinder components.
  2. Inspect the rod and cylinder: Before assembly, carefully check the cylinder bore and piston rod surface for scratches, burrs, or pitting. Even the best seals won't work on a damaged surface.
  3. Use seal installation tools: Do not use sharp metal tools (e.g., screwdrivers) that can damage the seals. Use dedicated plastic installation tools.
  4. Lubricate during assembly: Before installation, coat all seals with clean hydraulic oil. This will ease their seating and prevent damage.

Frequently Asked Questions (FAQ)

1. Does this kit fit both slew rams?

No, the price is for a repair kit for one cylinder. For a complete overhaul of the slew mechanism (which consists of two rams), you will need two such kits.

2. How do I know if I have a rack and pinion slew or a slew ring system?

In a rack and pinion system, two parallel hydraulic rams are visible under the kingpost. In newer slew ring systems, there is a large, circular slewing ring gear and one or two hydraulic slew motors under the kingpost.
