The Wabco 9617020504 Support Sheet is a critical component within air brake systems, specifically utilized in air valves. This part provides essential support and sealing functionality, ensuring the reliable operation of the braking system. It is designed to meet OE specifications, contributing to consistent performance and durability. This component measures 5 x 24 x 23 mm. This sheet basically acts as a mounting point and a bit of a cushion for the air valve. It provides a stable surface for the valve to attach to, and it helps absorb some of the vibration from the road and the movement of the truck. It also helps to distribute the load evenly, preventing stress cracks or damage to the valve itself. It’s a pretty simple part, but crucial for everything working right. It’s part of your air brake system, obviously, and specifically related to how the air valves operate. The air valves control the flow of air to your brake chambers, which is what actually pushes the brakes on. This support sheet keeps that valve securely positioned so it can respond correctly when you hit the brakes. Think of it as a foundation – a solid foundation is essential for anything to work reliably. It’s important because without it, the valve is just… floating. It can move around too much, which affects the accuracy of the brake signal. You’ll notice if this sheet is damaged or missing because the brakes might feel spongy or inconsistent, or you could have air leaks. That’s not something you want happening, especially when you’re trying to stop a big rig. A damaged sheet can cause a whole cascade of problems, so it's best to replace it when you see wear and tear. You can find these pretty easily, Fixparts Online has a good selection, but any reputable truck parts place will carry them. Replacing it is a relatively simple fix that can keep you safe on the road. Quality assurance: Support Sheet (MPN 9617020504) comes with a 12-month warranty!
