A1: The most reliable method is to physically match the part number. Remove the existing pump cover and cross-reference the number stamped on it with the OEM numbers listed in the “OEM Cross-Reference” section above. The primary fit is for pumps using cover number 294184-0030 or its variants.

Q2: What is the installation procedure for this pump cover?
A2: Installation requires a clean work environment. After ensuring the pump housing and new cover surfaces are clean and free of debris, carefully position the new cover with the appropriate gasket (if required, not included).

Always consult the official service manual for the specific engine or pump model.
