Complete bottom-end gasket set for D1403, D1503 and D1703 Kubota engines.

Part No BS43


This bottom gasket set is universal , it covers from the earliest version of this engine to the latest D1403, D1503, D1703, D1803


The early versions of this engine gasket sets were available as sets. The later version of this engine no gasket set is available from original equipment suppliers and all gaskets seals and "O" Rings etc have to be identified and ordered as each and every part which is time consuming !! We at Kubotaman have made this easier by making up this comprehensive gasket set.
