HOUSING ASSEMBLY CONTINUED
Hexagonal jam nut torque is critical. Nut must be torqued to 600 to 625 lb-ft (815 to
845 Nm) using a torque wrench. Insufficient torque will cause bearing slippage and
excessive torque will cause bearing wear. DO NOT use an ESNA nut. ESNA nut does not
have capacity for higher torque. Failure to follow this caution may result in damage.
4. Support housing assembly (Figure 15, Item 1) by clamping gear (Figure 15, Item 2) in a vise. Use soft,
protective vise jaws being careful not to damage gear).
5. Install hexagonal jam nut (Figure 15, Item 3) on gear (Figure 15, Item 2).
6. Torque jam nut (Figure 15, Item 3) to 600 to 625 lb-ft (815 to 845 Nm).
