    GENERAL DISCLAIMER - PLEASE READ! The following engines on this page have some similar specifications as your CRAFTSMAN Z 8400's engine.

Although any of these engines may not be exactly (100%) the same as for your CRAFTSMAN Z 8400's engine , we feel very confident and are doing our best from our many years of experience to show you the closest engines we have in stock that have some similar specifications as your original engine, such as crankshaft diameter and length and mounting bolt pattern that may work for your equipment. Your exact original engine may not be available because it may: be too old to be in production or discontinued due to some EPA regulations.

Our customers may had bought any of these engines from us and may had done some modifications to adapt to work with their equipment including, but not limited to: transferring the wire harnesses from their old engines to the new engines, tappering the mounting holes, drilling new mounting holes on mower's decks, cutting and welding mufflers, ...etc.

Although we spent a lot of time to prepare, review and compose this page, the information here may not be 100% accurate as we collected them from our experience and from our customers on the daily basis. You should replace your old engine with the same brand, type, and series, specifications to avoid major modifications. Please contact us first if you have any questions or want to confirm before purchasing. We are here to help!
