SK117 Conversion Seal Kit

This kit services a SMALL percentage of Japanese made Sumitomo made steering valves, that have seal bores that measure 1.338 ” (34mm) and use a lip seal which we currently do not stock. This conversion kit is designed to keep your steering valve serviceable, as this will keep you from scrapping a usable steering valve just because you can’t get a seal kit!

It converts the steering unit to a standard seal design that has been used since the 1960’s, and will seal the following units:

  • WEE130Z20KUBD
  • WEE145Z20KUUD
  • WEE130Z20KUUE
  • And Possibly others

Direct replacement for the following Kubota Sale Kit Part Numbers:
