tightening the locknuts finger tight. Tighten the locknuts of one hub to ½ the stated torque

Tighten the locknuts of the intermediate member to ½ the stated torque value in table 1.
Repeat the process but tightening to the full torque value (see table 1). It is also recommended

hours of operation to ensure proper tightening.
