Wabco 9700513422 Valve Piston Kit

Description

This kit contains a valve and piston, designed for use in drivetrain clutch systems as a repair component. Specifically engineered for optimal performance and durability, this Wabco kit, with MPN 9700513422, restores the clutch system to OE specification. Its dimensions are 154 x 100 x 210 mm, ensuring a precise fit and reliable operation, contributing to enhanced clutch performance and longevity.

Key Features & Benefits

Basically, this kit replaces the internal workings of your hydraulic clutch release cylinder. It's got a piston, some valves, springs, and seals all working together. The piston moves when you push the clutch pedal, and the valves control how the hydraulic fluid flows to actually disengage the clutch from the engine. Think of it like a tiny, powerful pump inside your clutch system. This all lives inside the clutch slave cylinder – the part that actually pushes on the fork to move the clutch. When you press the clutch pedal, it sends fluid pressure to this slave cylinder, and this kit is what translates that pressure into mechanical movement. It's the bridge between your foot and the gears changing.

Symptoms, Risks & Replacements

Honestly, if this kit starts failing, you’ll notice it. You’ll probably get a soft or spongy clutch pedal – meaning it doesn’t feel firm when you press it. Or you might have trouble getting into gear, or the clutch might not fully disengage, leading to grinding noises. Left unchecked, it can make it really difficult, or even impossible, to shift. This kit essentially acts like a shield against wear and tear inside that cylinder, and eventually all the seals and the piston itself will wear out. It's a relatively inexpensive fix compared to replacing the entire slave cylinder, and a lot of guys do it as preventative maintenance, especially on older vehicles. You can find a good selection of these at places like Fixparts Online. It’s a job most experienced DIYers can tackle, but if you're not comfortable working with hydraulics, definitely have a pro handle it.
