A heavy-duty slew pinion shaft, a central component of the backhoe slew mechanism in older machines with a rack and pinion system. Made of heat-treated steel, it transfers the entire force from the hydraulic rams to the kingpost, enabling the arm to slew. Its precise manufacturing is crucial for maintaining smooth and accurate operation.

| Brand (Machine Type) | Model |
|---|---|
| JCB (Backhoe Loaders) | 3CX, 4CX (models manufactured up to approx. 1997 with rack and pinion slew) |
The list above is for reference. It is crucial to ensure that your machine has the older rack and pinion slew system.
A slew mechanism overhaul is a major operation. You must also replace the upper and lower shaft seals, as well as the bushings and shims. Before assembly, generously lubricate the teeth and journals of the shaft with high-quality HYPTRON grease to ensure smooth operation and minimize friction.
The slew pinion transfers the entire force generated by the hydraulic rams to the backhoe arm. Its teeth mesh with the rack, converting the linear motion of the rams into rotational motion. Wear of this component leads to a loss of precision, and its failure will completely immobilize the backhoe arm.
Replace the shaft if you notice any of the following symptoms:
✓ Regain Digging Precision: The GX-AFTER Solution
Play in the slew mechanism is not just an inconvenience; it's a loss of efficiency and a risk of damage to other components. The GX-AFTER slew pinion is a smart choice that allows you to restore the machine's factory precision. Made of properly hardened steel, it guarantees durability and reliability you can count on.
Tired of the backhoe arm "swinging" from side to side? Don't wait for a complete machine breakdown!
Our slew pinion is available off-the-shelf. Order now, eliminate the play, and work with precision that translates into real profit!
Most likely not. Around 1997, JCB began introducing a newer slew ring system, which uses a different shaft. This model is intended for the older system with two rams and a rack.
2. Does the set include bushings and seals?No, this offer is for the slew pinion shaft only. Bushings, seals, and shims should be purchased separately.
