Wabco 9700516040 Clutch Servo

Description

The Wabco 9700516040 Clutch Servo is a vital component in heavy-duty vehicle clutch systems. This device uses hydraulic pressure to assist in clutch actuation, significantly reducing driver effort and improving operational efficiency, primarily in commercial vehicles. It's engineered to OE specification and features dimensions of 124 x 116 x 395 mm. With a stroke of 83.5 mm and a maximum operating pressure of 10.0 bar, this clutch servo delivers reliable and consistent performance across a temperature range of -30°C to +100°C. Multiple port threads are included for flexible installation: 2000 - 1/2, 2000 - 3/8, and Ø 8.0 / 11.0 mm. The calculated volume is 5.682 and the distance between mounting holes is 110 mm.

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.
