GX-AFTER BRAKE SEPARATOR PLATE (STEEL) FOR CAT 428, 428II - 9R2476

Technical Specification and Compatibility

A key component of the wet brake pack – this is a precision-made steel brake separator plate by GX-AFTER. It is designed for the drive axles in CATERPILLAR 428 and 428II backhoe loaders. The separator plate operates in an oil bath, alternating with the friction discs. Its perfectly flat, high-strength steel surface and precise thickness (2.7 mm) are essential for ensuring correct braking force, proper friction, and effective heat dissipation from the brake pack.

Part number: 9R2476 / 9R-2476
Manufacturer: GX-AFTER
Material: Steel
Outer Diameter: 209.3 mm
Inner Diameter: 114.3 mm
Thickness: 2.7 mm

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 Brake Service

  • › Friction Discs: Steel plates work in alternation with friction discs. The entire pack should always be replaced together.
  • › Axle Oil (with LSD additive): Required to refill the axle after the brake service.
  • › Axle Seals: Brake replacement requires removing the planetary hub, which necessitates replacing the axle seals.

Application in machines

Brand Type / Series / Model
CATERPILLAR Backhoe Loaders: 428, 428 Series II

The list above is for reference. We recommend verifying the part number or exact dimensions (OD 209.3mm / ID 114.3mm / Thickness 2.7mm) before purchasing.

⚠️ Safety Warning

Servicing wet brakes in a drive axle is an advanced repair. It requires the machine to be securely supported on stands and involves removing heavy components (wheels, planetary hub). A faulty brake system is a fatal hazard. Ensure the system is properly bled after repair.

Part's Role in the Machine and Failure Diagnostics

The steel separator plate is the friction counter-surface in a wet brake pack. It alternates with the friction discs. A piston compresses this pack, and the friction between the plates and discs creates the braking force. Wear or damage to these plates is a primary cause of brake failure.

  • › Weak or fading braking power (pedal feels spongy or goes to the floor).
  • › Loud grinding, scraping, or squealing from the axle during braking.
  • › Overheating of the axle and a distinct burning smell.
  • › Presence of excessive metal shavings in the axle oil (a sign of metal-on-metal contact).

🔧 Expert's Guide: Key Installation Tips

  1. Replace as a Kit: Never replace just one plate or only the friction discs. Always replace the entire kit (all steel plates and all friction discs) on both sides of the axle to ensure even braking and correct pack clearance.
  2. Absolute Cleanliness: The brake system is a hydraulic system. Assembly must be done in sterile conditions. The smallest contaminant can damage the brake pump or piston.
  3. Oil Submersion: Before assembly, all new steel plates and friction discs must be generously soaked in the correct axle oil.
  4. Bleeding: After reassembly and refilling with oil, the brake system must be thoroughly bled according to the service procedure.

Frequently Asked Questions (FAQ)

1. What is the difference between a friction disc and a separator plate?

A Separator Plate (9R2476) is a smooth, solid steel disc. A Friction Disc (sold separately) has a friction material (like bronze or Kevlar) bonded to it and features internal splines (teeth) that lock onto the axle shaft.

2. Can I just replace the worn friction discs and reuse these steel plates?

This is highly discouraged. If the friction discs are worn, the steel plates are almost certainly overheated, discolored, or warped. Reusing old plates with new friction discs will cause the new discs to be destroyed very quickly and will result in a loss of braking power.

3. Will this plate fit a CAT 428C, D, E, or F?

No. This part number 9R2476 is specific to the older CATERPILLAR 428 and 428 Series II. Newer machines (C, D, E, F) use completely different axles and brake packs with different part numbers and dimensions.
