Take the guesswork out of Mercedes cam timing. The Oni Tools Camshaft Adjuster Tool Set accurately indexes the pulse/reluctor wheel when the camshaft is removed, helping you restore factory timing on popular Mercedes engines. This 4-piece quadrant set is compatible with M152, M276.8/.9, M278 and M157 engines and replaces OEM tool 278 589 00 23 00 (278589002300), giving professional technicians and DIY enthusiasts an OE-style procedure at a smarter price. Precision-machined alloy blocks hold the wheel at the correct angle while you service timing chains, cam phasers or seals, preventing misalignment and avoiding rework. Typical applications include E-, S-, CLS-, ML/GL/GLS-Class (including AMG models running M157). If you’re rebuilding, resealing or retiming, this kit keeps the job fast, accurate and repeatable—all without dealership tooling.
