FAQ

Q1: How do I confirm this timing cover will fit my specific Mitsubishi 4D56 engine?
A1: The most reliable method is to cross-reference the part number cast or stamped on your original timing cover. Match it with the OEM numbers listed in the OEM Cross-Reference section (4DQ5, MD172083, MD172084). Providing your engine’s model code and serial number to our technical team can also ensure a perfect match.

Q2: Is any additional hardware or gasket required for installation?
A2: Yes. Installation typically requires a new timing cover gasket and front crankshaft seal. We recommend replacing these critical sealing components during installation to prevent future oil leaks. The necessary bolts are usually reused, but inspect them for wear or damage.

Q3: What is the typical lead time for delivery to Europe or North America?
A3: For in-stock items, sea freight to major European or North American ports generally takes 25-35 days. Air freight options are available for urgent requirements, with delivery in 5-10 business days. We provide real-time tracking from dispatch to arrival at your designated port or warehouse.
