Genuine ZF Diaphragm (Flex Plate) 4657.230.030

Ensure smooth power transfer from your engine to your transmission with the Genuine ZF Diaphragm (Material Number: 4657.230.030). This heavy-duty steel flex plate is the core component of the Engine Connection Group for ZF 4WG210 series transmissions.

As an Authorized Service Dealer, Tianjin Xiaohang stocks only original ZF connection parts. Cheap aftermarket diaphragms often suffer from fatigue cracks, leading to catastrophic failure of the torque converter or engine crankshaft.

Condition: New / Genuine OEM

Part Name: Diaphragm / Membrane / Flex Plate

ZF Material Number: 4657.230.030

Material: High-Tensile Spring Steel

Function & Importance

The Diaphragm (4657.230.030) acts as the flexible interface between the engine flywheel and the transmission torque converter. Its role is critical:

• Torque Transmission: Transfers 100% of the engine’s power to the drivetrain.
• Vibration Damping: Absorbs axial vibrations and slight misalignments between the engine and transmission, protecting the bearings.
• Compensation: Allows for thermal expansion during heavy operation.

Note: Depending on the specific 4WG210 configuration, this part may be installed singly or in a pack. Always check your spare parts catalog.

Signs of Failure (When to Replace)

Diaphragms are wear items subject to immense stress. Inspect or replace 4657.230.030 if you notice:

Rattling Noise: A metallic clatter from the bell housing area, especially at idle or shutdown.

Vibration: Excessive vibration felt in the cab, indicating the plate has cracked or warped.

Starting Issues: In severe cases, a sheared plate will disconnect the engine from the transmission, causing a total loss of drive.

Pro Tip: We recommend replacing the mounting bolts and washers whenever you replace the diaphragm to ensure proper torque retention.

Compatibility

This part is widely used in the Engine Connection assembly of ZF 4WG210 transmissions found in:

• Wheel Loaders (e.g., XCMG, Liugong, SDLG, Hyundai)
• Motor Graders
• Tow Tractors

Fitment Check: ZF uses different diaphragms (e.g., 4644.330.239 vs 4657.230.030) depending on the Engine Brand (Cummins, Deutz, Weichai). Please send us your transmission serial number to confirm this is the correct plate for your machine.
