Wabco 9700518220 Clutch Servo

Description

The Wabco 9700518220 is a Clutch Servo designed to assist in the operation of a vehicle's clutch system, commonly found in heavy-duty commercial vehicles. This device utilizes hydraulic or pneumatic pressure to reduce the effort required to disengage the clutch, improving driver comfort and reducing fatigue. The servo measures 148 x 148 x 395 mm and features a stroke of 85.0 mm, a maximum operating pressure of 10.0 bar, and mounting points for 4x Ø 9.0 mm bolts. It is engineered to OE specification, ensuring reliable performance and compatibility. With port threads including M12 x 1.5, M16 x 1.5 JED - 464-0, Flap Exhaust and Ø 8.0 mm, and a ball-ended push-rod thread of Ø 16.0 mm, this servo provides precise and consistent clutch control.

Key Features & Benefits

Basically, this little guy takes the fluid pressure from your hydraulic system and uses it to help push the clutch fork. It doesn’t do the whole job, it just assists. It multiplies the force you give it with the clutch pedal. It operates the clutch release bearing, engaging and disengaging the engine from the transmission. Some systems use it to fully automate the clutch, meaning no clutch pedal at all, but even then, it's still doing that assisting work. Think of it like power steering, but for your clutch. It takes some of the effort out of pushing the clutch, making it smoother and easier, especially in heavy traffic or with a performance clutch. It's part of the overall hydraulic clutch system, working alongside the master and slave cylinders. It really makes a difference in driver comfort and reduces fatigue.

Symptoms, Risks & Replacements

If this thing fails, you’ll notice it pretty quickly. You’ll likely have a really hard time getting the car into gear, or it might not go into gear at all. It can feel like the clutch pedal is incredibly stiff or unresponsive. Sometimes it’ll cause intermittent issues – it might work fine for a while, then suddenly become difficult. It’s a key part of making your car drive smoothly and reliably. You can find them pretty easily these days; I've seen a good selection over at Fixparts Online if you're looking for one. Ignoring a failing clutch servo can put extra strain on other parts of the drivetrain, so it's best to address it when you notice a problem.
