31470-12040 Clutch Driven Cylinder for Toyota

31470-12040 Clutch Driven Cylinder For Toyota is a hydraulic actuator designed for classic Corolla models. As the core component of the clutch system, its core function is to convert the mechanical force input by the pedal into hydraulic thrust and accurately control the separation and engagement of the clutch plate. The component is cast with high-strength cast iron, and the surface is treated with electrophoresis rust prevention. The piston diameter is 13/16 inches (about 20.6mm), which can withstand 32MPa hydraulic pressure and is suitable for 1.6L and 1.8L engine versions of 1984-1985 Toyota Corolla DX, LE and other models.

The slave cylinder adopts a single piston structure, and the piston seal is made of fluororubber. The temperature range covers -40℃ to 180℃, which can effectively cope with the heat accumulation caused by high-frequency semi-clutch operation. For use in cold regions, its brake fluid is compatible with DOT3/DOT4 standards, maintaining hydraulic system performance at -40°C, ensuring reliability during winter start-up.

In terms of adaptability, the 31470-12040 slave cylinder covers multiple generations of Corolla models, including the E7 chassis from 1979 to 1983, the E8 hatchback from 1983 to 1989, and some hybrid models from 2015 to 2019. Its OE number is compatible with models such as 31470-12041 and 31470-12043.
