Storage & logistics
Bulk turbos for the OM651 211 CDI 150 hp must be stored in a dry, temperature-controlled environment to prevent moisture damage or seal degradation. Garages should rotate stock based on expiration dates provided by the supplier, typically 12 to 24 months for remanufactured units. Avoid stacking heavy items on top of packaging to prevent deformation of the turbo housing or internal components. For single-unit purchases, store in original packaging until installation to maintain protection against dust and contaminants.
