Robin-Subaru engine logo
For each model there may be many different versions called specifications. Each specification will be unique in some way. The difference may only be the paint color or it may have a different type of PTO or some other significant difference.
 
The specification and code number together are known as the PRODUCT NUMBER.
 
All Subaru 4 cycle engines have a Product Number label similar to the labels illustrated below.
