Rotate gear assembly (7) for a minimum of three revolutions or rotate gear assembly (7) until the rolling resistance of the gear assembly diminishes to a steady level. Use a mallet to tap the shaft lightly while you rotate the gear.
Illustration 20 g02531178
Install Tooling (D) on the input transfer gear housing, as shown. Measure the end play of the gear assembly by lifting on the gear assembly. Note: The desired end play for the gear is 0.152 mm (0.0060 inch). The maximum end play for the gear is 0.203 mm (0.0080 inch). The end play of the gear must be measured with a dial indicator in order to determine the correct gear end play.
If the end play is not within the correct range, perform Steps 21 through 26 again. Add shims or remove shims in order to achieve the correct end play, if necessary.
Rotate the shaft after the correct end play is achieved. Make sure that the shaft turns freely in order to verify that the bearings are not binding. End By:
Connect the input transfer gears
