its not that easy. we dealers look up everything by model number, not engine numbers. It would be nearly impossible for a dealer to sell anything with any level of confidence that its the right part. Thats why you don't expect parts support on anything gray market.

I had a B7001 gray market a few years back. Kubota dealers dont like to deal with gray market tractors for many reasons. When I needed parts, I would order the part that was my tractors U.S. equivalent. In my case, it was the B7100.
