- Evaluate the supplier’s return policy and core deposit terms to protect your investment in case of compatibility issues or defects.
- For bulk orders, confirm the availability of batch discounts and wholesale pricing to optimize your workshop’s cost structure.
- Inspect the injector’s physical condition, including nozzle and cartridge integrity, to ensure it meets the OM651’s high-pressure demands.
Storage & logistics
Proper storage of OM651 injectors is critical to maintaining their performance and preventing contamination. Keep reconditioned units in a dry, temperature-controlled environment away from direct sunlight and corrosive substances. For garages, organize injectors by motorization and power output to streamline retrieval during service jobs. Always handle injectors with care, avoiding contact with the nozzle or electrical connectors to preserve their precision. If storing for extended periods, use sealed containers with desiccant packs to mitigate humidity risks and ensure the injector’s readiness for immediate use.
