Wabco 4700530240 Clutch Master Cylinder

Description

The Wabco 4700530240 Clutch Master Cylinder is a critical component in a vehicle's clutch system, responsible for initiating the clutch disengagement process. It's used in heavy-duty vehicles and commercial applications where reliable clutch operation is essential. This master cylinder utilizes hydraulic pressure to transmit force from the clutch pedal to the release bearing, allowing for smooth gear changes. Its OE specification ensures a precise fit and consistent performance, improving both driver comfort and system longevity. The cylinder measures 140 x 59 x 226 mm and is compatible with DOT 3 and DOT 4 fluids adhering to SAE J 1703 standards, boasting a maximum operating pressure of 120.0 bar. It features M8 x 1.25 mounting and M14 x 1.5 port thread, and operates effectively within a temperature range of -40°C to +80°C with a stroke of 36.0mm.

Key Features & Benefits

Basically, it takes the pressure from your foot when you push the clutch pedal and turns that into hydraulic pressure. It’s a little piston inside a cylinder filled with brake fluid. When you press the pedal, that piston moves, pushing the fluid through the hydraulic line. That fluid then goes to the slave cylinder, which actually disengages the clutch. It’s all about converting your foot power into the force needed to smoothly shift gears. It’s a key piece of your clutch system, sitting up near the pedal itself. Think of it as the starting point for disengaging the engine from the transmission. Without it working properly, you won't be able to get the engine and transmission to separate, meaning you'd have trouble shifting gears, or maybe not be able to shift at all. It's part of the hydraulic system, so it works hand – in – hand with the slave cylinder and the lines.

Symptoms, Risks & Replacements

A failing master cylinder can cause a lot of headaches. You’ll notice if it’s going bad because the clutch pedal might feel spongy, or it might even sink to the floor when you hold it down. Sometimes it just gets really hard to push. It can also cause difficulty getting into gear, or even the inability to shift at all. It’s one of those parts that, when it's good, you don’t think about it. But when it fails, it makes driving pretty impossible.
