K-2072 Eaton Fuller Repair Kit Master Valve

The Eaton Fuller K-2072 or K2072 is a master valve repair kit for the shift valve assembly on Eaton Fuller transmissions. The kit rebuilds the master valve with a full complement of internal service parts: a valve actuator, a split-actuator detent, three 5/32 steel balls, two O-rings and an O-ring retainer, a shift valve seal, six compression springs across three spring types, a wave washer, and grease for reassembly. An instruction sheet is included to guide the rebuild. Buying the complete kit keeps every worn seal, spring, and small part matched to one part number instead of sourcing loose pieces. Call us to confirm proper fit for your transmission.
