4. Remove the driveshaft from the machine.

5. Install the new driveshaft to the clutch with 6 hex-socket head bolts (M8-1.25 x 30 mm); refer to Figure 2.

   Note: The bolt hole orientation to the clutch flange is not important.

6. In a star pattern, torque the 6 hex-socket head bolts to 23 to 29 N∙m (17 to 21 ft-lb).

   Important: If you separate the PTO-driveshaft telescoping end from the clutch end, ensure that the arrows align when you install the telescoping end (Figure 3).

   Important: : If the arrows on the driveshaft are not aligned, severe imbalance may occur in the driveline system.
