DIFFERENTIAL SEPARATOR PLATE (LSD) SUITABLE FOR JCB 3CX, 4CX - 450/20403

Technical Specification and Compatibility

A high-quality steel separator plate for the Limited Slip Differential (LSD). It is a key component of the differential's clutch pack, working alternately with the friction plates. It is responsible for transferring clamping force and providing the correct friction surface, which is essential for the effective operation of the limited-slip mechanism and maintaining traction in difficult terrain.

Part number: 450/20403
Outer Diameter (mm): 98.7
Inner Diameter (mm): 63
Thickness (mm): 1.6
Number of Teeth (Tabs): 4

GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

Essential for Assembly

  • › Friction plates: Always replace as a complete set with new friction plates, part no. 450/20402.
  • › Axle oil with LS additive: Use dedicated oil to ensure correct limited-slip operation.

Application in machines

Brand (Machine Type) Model
JCB (Backhoe Loaders) 2CX, 3CX, 4CX
JCB (Telehandlers) Loadall
JCB (Wheel Loaders) Various models
JCB (Rollers) Vibromax

The list above is for reference. Before purchasing, we recommend verifying the part number in the parts catalogue for your machine.

⚠️ Safety Warning

Working on the drive axle requires lifting and securing the machine. Always use certified axle stands with an appropriate load capacity. Never rely solely on the machine's hydraulics or a jack.

Part's Role in the Machine and Failure Diagnostics

The steel plates, working in a pack with the friction plates, form the limited-slip differential clutch. Their wear or overheating (which leads to a loss of flatness) causes the differential to act like an open diff, leading to a loss of traction in difficult terrain.

  • › One wheel spinning while the other on the same axle remains stationary.
  • › Loss of ability to drive in difficult terrain (mud, snow).
  • › "Popping" or skipping in the drive axle when turning.
  • › Presence of a large amount of metal filings in the axle oil.

Peace of Mind Guarantee: Why Choose Our Offer?

A faulty limited-slip diff means an immobilized machine at the worst moment.

Don't let one spinning wheel stop your entire job. The cost of replacing the plates is minimal compared to the losses caused by downtime. Invest in traction – order a new repair kit and regain your drive's full capability.

🔧 Expert's Guide: Key Installation Tips

  1. Maintain cleanliness: Disassembling a differential requires the utmost cleanliness. Any contaminants that get inside can damage bearings and gears.
  2. Replace as a set: Always replace all steel separator plates and friction plates in the differential to ensure even wear and proper operation.
  3. Check for flatness: Before installation, ensure the new separator plates are perfectly flat and have no transport damage.
  4. Maintain the correct order: Stack the steel plates and friction plates alternately, according to the diagram in the service manual. A mistake in the sequence will prevent the LSD from working correctly.

Frequently Asked Questions (FAQ)

1. What is a Limited Slip Differential (LSD)?

An LSD is a type of differential that, in the event of one wheel losing traction, automatically transfers a portion of the torque to the other wheel. This is achieved through a clutch pack of friction and separator plates that clamp together under load, limiting the difference in rotational speed between the wheels.

2. Do I need to use special oil for an axle with an LSD?

Yes, this is absolutely crucial. You must use a gear oil with an "LS" (Limited Slip) additive. Standard gear oil will cause the plates to "stick-slip," which manifests as loud popping and jerking from the axle when turning.

3. How can I check if the limited-slip in my axle is working?

The simplest test is to lift the entire drive axle and try to turn one wheel by hand. If the other wheel turns in the same direction (or offers very high resistance), the LSD is working. If it spins freely in the opposite direction, the plates are worn out.
