DIFFERENTIAL FRICTION PLATE (LSD) SUITABLE FOR JCB 3CX, 4CX - 450/20402

Technical Specification and Compatibility

A high-quality friction plate for the Limited Slip Differential (LSD). It is a key component of the differential's clutch pack, responsible for locking and equalizing the rotational speed of the wheels in case of traction loss. Made of sintered bronze, it guarantees an optimal friction coefficient and high wear resistance, which is essential for the proper functioning of the drive in difficult terrain.

Part number: 450/20402
Outer Diameter (mm): 88
Inner Diameter (mm): 57.3
Thickness (mm): 2.1
Number of Teeth: 28

FEROSTEM is a brand that has been providing proven solutions for spare parts for industrial and construction machinery for years. Bet on proven components – choose parts that combine high quality with a reasonable price!

Essential for Assembly

  • › Steel separator plates: Always replace as a complete set with new steel plates - 450/20403.
  • › Axle oil with LS additive: Use dedicated oil to ensure correct limited-slip operation.
  • › New axle shaft seals: An ideal opportunity to replace them while the differential is removed.

Application in machines

Brand (Machine Type) Model
JCB (Backhoe Loaders) 2CX, 3CX, 4CX, 5CX
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 friction plates in a limited-slip differential (LSD) are responsible for transferring torque to the wheel with more grip. When they wear out, the differential acts 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 (in case of mechanical damage).
  • › 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 friction plates is minimal compared to the losses caused by downtime or the need for a recovery. Invest in traction – order a new set of FEROSTEM plates 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 friction plates and steel separator plates in the differential to ensure even wear and proper operation.
  3. Soak the plates in oil: Before assembly, soak the new friction plates in the dedicated axle oil for at least 30 minutes. This prevents damage during the first few rotations.
  4. Maintain the correct order: Stack the friction plates and steel 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.
