A4030501236 Mercedes-Benz Trucks Bearing Block

This little part basically provides a really smooth, low – friction surface for your rocker arms to pivot on. It's a housing that holds a needle bearing, and that bearing is what lets everything move freely. Think of it like a really precise, miniature swivel point. It supports the rocker arm and allows it to transfer motion to open and close the valves. It's part of the valve train, which is honestly the heart of how your engine breathes. It’s up in the cylinder head, working with the camshaft to get the valves moving correctly. When the camshaft lobe pushes on the rocker arm, this bearing block is what allows that movement to happen smoothly. It’s a pretty critical connection point. If this bearing block wears out or fails, you'll notice if it gets bad. You’ll probably hear a ticking or tapping sound coming from the engine – it's that extra play and friction causing the noise. More seriously, it can lead to reduced engine performance, misfires, or even valve damage if it gets really bad. It’s not something you want to ignore. Luckily, they’re usually pretty straightforward to replace. You can find a good selection of them on sites like Fixparts Online, and there are plenty of guides online if you're comfortable doing the work yourself. If not, definitely take it to a mechanic. Your trust matters: Bearing Block (MPN A4030501236) comes with a 12-month warranty!
