Installation notes
The intermediate shaft is driven from front to rear through the housing during disassembly. Use a copper drift - never strike the shaft directly with steel. The shaft is slightly larger at the rear (0.004") than at the front. Installation requires correct placement of needle bearings, thrust washers and locking plate.
Compatibility
Dana 18 transfer cases had different intermediate shaft diameters: 3/4" (1941-1946), 1-1/8" (1946-1953/1955), and 1-1/4" (1953/1955-1971). Check the diameter of your original shaft before ordering. The diameter determines which bearings and gears are compatible.
Historical context
The Dana Spicer Model 18 transfer case was designed in 1940 and remained in production for thirty years. The intermediate shaft was enlarged over the years to provide a larger bearing surface.
