Clutch Pressure Plate (Diaphragm Spring) suitable for JCB - 445/05110

Technical Specification and Compatibility

A high-quality 445/05110 clutch pressure plate by GX-AFTER. This is a precision diaphragm spring (Belleville washer), a key component of the clutch pack in JCB machine transmissions (3CX, 4CX, Loaders). Its function is to exert a constant, strong pressure on the pack of friction discs and steel plates, ensuring they lock up to transfer drive.

Part Number: 445/05110
Type: Pressure Plate / Clutch Diaphragm Spring
Outer Diameter: 119 mm
Inner Diameter: 64.2 mm
Thickness: 2.7 mm

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

Features of the 445/05110 Pressure Plate

High Clamping Force: Made from high-grade spring steel to provide constant and strong clamping force on the clutch pack.
Fatigue Resistant: Material is resistant to repeated compression cycles and high temperatures inside the transmission.
Precise Dimensions: Exact dimensions (119 x 64.2 x 2.7 mm) guarantee correct seating and even pressure.
Critical for Transmissions: Essential for rebuilding reverser or gear clutches and eliminating slippage.

Application in machinery

Brand Type / Series / Model
JCB Backhoe Loaders: 3CX, 4CX
JCB Forklifts
JCB Telehandlers

The list above is for reference. It is crucial to verify the part number 445/05110 in your machine's transmission parts diagram.

Related Parts and Hardware

The 445/05110 pressure plate is part of a clutch pack. When replacing it, it is essential to also replace the friction discs and steel plates, and to inspect the piston and piston seals in the clutch drum.

⚠️ Safety Warning

A cracked or fatigued pressure plate will lead to a loss of clamping force on the clutch pack. This causes severe clutch slippage, loss of drive, or failure to change direction. This can be extremely dangerous, e.g., when operating on a slope. An overheating clutch will burn the oil and destroy the entire transmission.

Part Role in the Machine and Failure Diagnostics

The 445/05110 plate is a diaphragm spring. In Powershift transmissions or reversers, it is installed in the clutch drum. When oil pressure pushes the piston, the piston compresses this spring, which then applies immense force to the stack of friction and steel plates, locking them together to transfer drive. When the oil pressure is released, the spring expands, releasing the pressure and disengaging the drive.

  • Transmission "slipping" (engine revs, but machine doesn't accelerate).
  • Delayed engagement when changing direction (Fwd/Rev) or shifting gears.
  • Loss of drive in one or more gears or directions.
  • Visible cracks or deformation of the plate upon clutch disassembly.
  • Loss of spring tension (due to overheating), resulting in insufficient clamping force.

🔧 Expert Guide: Key Installation Tips

  1. Absolute Cleanliness: Assembling transmission components requires sterile cleanliness. Any contaminant can damage seals or block valves.
  2. Replace as a Set: Always replace diaphragm springs together with a complete set of friction discs and steel plates.
  3. Correct Order: Pay close attention to the sequence and orientation of pressure plates, discs, and steel plates when assembling the pack.
  4. Soak Friction Discs: Before installation, new friction discs must be soaked in clean transmission oil (we recommend HYPTRON) for at least 30 minutes.
  5. Check Piston Seals: Before installing the plate, always check the condition of the piston and its seals (inner and outer). A leaking piston is a common cause of clutch slip.

Frequently Asked Questions (FAQ)

What is a diaphragm spring?

It is a special type of coned-disc spring (Belleville spring). In transmissions, it is used to apply a very high clamping force in a small space, which is necessary to lock a clutch pack.

Why do I have to replace this plate with the friction discs?

When a clutch slips, it generates extreme heat. This heat causes the spring plate to lose its tension (it "softens"). Installing new friction discs with an old, overheated pressure plate will result in insufficient clamping force, and the new discs will burn up very quickly.

What is the difference between 445/10803 and 445/05110?

These are completely different parts. 445/10803 and 445/10802 are small teflon washers for the gear shift lever mechanism in the cab. This product (445/05110) is a large, metal diaphragm spring that works inside the transmission.
