Note: 20R-0128 Transfer Case As is available as the Reman service replacement for both 345-2394 Transfer Case As and 419-8133 Transfer Case As. One 134-9817 Transfer Case As is required as a core return when purchasing a 20R-0128 Transfer Case As.
Note: The bearing design that is used on the idler gear no longer requires end play adjustment. The design still requires end play to be checked. Ensure that no preload is present. The former 230-6346 Transmission Ar will be replaced by 347-0183 Transmission Ar. The 347-0183 Transmission Ar will contain 345-2392 Output Transfer Gear Gp which uses the straight roller bearings. The Specification manual will contain all necessary information regarding end play measurements. Refer to the Disassembly and Assembly manuals for instructions on assembling the new design of the output transfer case.
