Here's why:
* Ford produced a wide range of industrial engines with 172 cid displacements. Each engine may have different specifications and configurations.
* Engine specifications vary even within the same model year. Factors like carburetion, ignition system, and camshaft profiles can influence firing order and timing.
To get the correct information, you need to identify the following:
* Engine model number: This will be found on a data plate or sticker on the engine.
* Engine serial number: This helps pinpoint the specific build.
* Year of manufacture: Helps narrow down potential variations.
* Application: Knowing what the engine was used for (forklift, generator, etc.) can provide clues about its configuration.
Once you have this information, you can:
* Consult a Ford service manual: These manuals contain detailed specifications for specific engines.
* Contact a Ford dealer or authorized repair shop: They have access to technical resources and can assist with finding the correct firing order and timing.
* Search online resources: Websites like Ford forums, online service manuals, and automotive parts catalogs might have specific information about your engine.
Please remember: Incorrect firing order and timing can damage your engine, so it's crucial to find the correct information for your specific engine.
