Eaton Fuller K-3423 or K3423 is a basic rebuild kit for Fuller manual transmissions, sold by Pro Gear and Transmission. It is listed in the Kits and Assemblies section of our parts manuals for the FS-5406A, FS-5406N, FS-6406A, FS-6406N, FSB-5406B, FSO-6406A and FSO-8406A, one kit per assembly.
The kit gathers the wear items a basic overhaul calls for: bearing cups and cones, roller and needle bearings, two oil seals, snap rings, four shift bar housing springs, a front countershaft bore plug, plus a K-2183 shim kit and a K-7028 gasket kit. Because the bearings and seals come together, they are renewed as a set while the transmission is apart instead of being sourced one at a time. Call us to confirm proper fit for your unit.
