9700516670 WABCO Pneumatic Clutch Servo Booster Control for Commercial Truck AMT Transmission

The WABCO WABCO Clutch Servo (part number 9700516670) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Max Working Pressure 10 bar, temperature range -40°C ~ +80°C, Stroke 60 mm, mounting hole spacing 130 mm, fixed by 4*Ø9 mm bolts, Port Threads M14*1.5, M16*1.5, M10*1.0.

Using compressed air to multiply pedal force, the servo greatly reduces the effort needed to disengage the clutch and delivers smooth, repeatable engagement that protects the clutch mechanism. Sealed against dirt and moisture, it is built to last in the demanding environment of a commercial vehicle.

Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.
