Scribe alignment marks (25) on the third-fourth gear synchronizer hub and sleeve for assembly reference.
Position the jaws of a split-type puller (e.g., Tool J-22912-01) between the third and second gears on the output shaft. Ensure that the puller jaws exert force firmly against the back of the third gear (26).
Place the output shaft (27) geartrain assembly in an arbor press and remove the third4ourth gear synchronizer hub and sleeve (28) and third gear (26) as an assembly.
