Genuine Toyota OEM Clutch Cover Assembly with Heavy-Duty Diaphragm Spring and Precision Heat Treatment for Hilux Fortuner Innova

The clutch cover assembly with Toyota Genuine OEM number 31210-0K310 is the factory-spec pressure plate unit for a range of Toyota commercial and SUV platforms. It houses the diaphragm spring and pressure plate that clamps the clutch disc against the flywheel, transmitting engine torque to the transmission.

This assembly is a direct replacement for the original factory unit, designed for vehicles equipped with manual transmissions that operate under frequent starts, towing, and mixed city/off-road conditions.

This Toyota clutch cover assembly 31210-0K310 directly replaces the factory unit in the following configurations:

Each Genuine Toyota clutch cover assembly meets Toyota's original equipment quality standards, including:

• Diaphragm spring load testing - clamping force verified against factory specification

• Material certification - steel grade confirmed to Toyota material standard
• Dimensional inspection - bolt hole alignment and cover geometry verified against OE blueprint
