Wabco 9129700640 Compressor

Description

This Wabco compressor (MPN: 9129700640) is a vital component of air brake systems, providing compressed air to actuate the brakes in commercial vehicles. It is designed for foot mounting and operates at 3000 RPM to deliver a consistent 10.0 bar of pressure. This single-cylinder compressor features lubrication supplied from the engine and operates using a normal pressure system with an unloader. Its dimensions are 167 x 128 x 217 mm, and it boasts a swept volume of 120 cm3 and a calculated volume of 4.639. This OE specification compressor offers reliable performance and durability for demanding braking applications.

Key Features & Benefits

This thing basically takes engine power and turns it into compressed air. It’s a pump, really. It draws in air, squeezes it down into a smaller space, and then stores it at high pressure. It also includes an unloader valve which periodically releases some of that pressure – think of it like letting a little air out of a tire to prevent it from overinflating. It’s constantly working when the engine is running, maintaining the right air pressure in your system. It's the heart of your air brake system. All those air brakes – the ones that stop your vehicle – rely on the pressure this compressor builds. That pressure is what pushes the air into the brake chambers, activating the brakes. It also powers other air – operated components, like the horn or sometimes even auxiliary suspension systems. Without it, you just wouldn't be able to safely and reliably stop.

Symptoms, Risks & Replacements

It’s critically important, honestly. The brakes are, obviously, the most vital safety system on any vehicle, but especially on something relying on air brakes. You’ll notice if this compressor is failing. You might experience longer braking distances, the brakes might feel spongy, or you’ll start seeing warning lights come on. A failing compressor means the air pressure drops, and that directly affects your ability to stop. Ignoring it isn’t an option. We carry a good selection of these – you can even find a lot of options over at Fixparts Online if you want to browse. Replacing a worn compressor is a lot cheaper – and certainly safer – than dealing with a brake failure.
