Setup, Compatibility & Care
Installation should always follow the equipment manufacturer's guidelines. Ensure the mounting surface is clean and free of debris from the old filter gasket before screwing on the new W 940/18. Hand-tighten the filter until the gasket makes contact, then follow with an additional turn as specified by the engine manual; do not overtighten, as this can damage the seal. This filter utilizes a 1-12 UNF thread, which is specific to heavy-duty applications, so always double-check your equipment's port specifications prior to mounting. For optimal care, replace the filter during every oil change interval to ensure the internal media and bypass valve continue to function within their designed tolerances.
