Eaton Fuller K-3479 or K3479 synchronizer kit, supplied by Pro Gear and Transmission. The kit consists of two synchronizer cups and one synchronizer assembly. The factory parts list carries it as a synchronizer kit, one per assembly, under Kits and Assemblies for the FS-4205A, FS-4205B, FS-4205C, FS-5205A, FS-5205B and FS-5205C.
A synchronizer brings the gear you are selecting up to the shaft's speed so the two mesh without clashing. Worn synchronizers show up as grinding on shifts, gears that resist going in, and a transmission that jumps out of gear, and the extra shifting effort can strain the clutch. Call us to confirm fit for your unit.
