Storage & logistics
Storing Mercedes-Benz OM654 M50d turbo exchange standards requires a controlled environment to prevent contamination or damage to the CHRA. Garages should use dedicated shelving with anti-static protection, while bulk shipments benefit from palletized storage in dry, temperature-regulated spaces. Regular inventory rotation ensures units remain within their shelf-life parameters, and clear labeling prevents mix-ups between variable geometry and standard turbos. For private buyers, storing a single unit in a clean, dry area away from direct sunlight preserves the turbo’s condition until installation.
