IMPORTANT: Keep the face of hub sleeves even to prevent hub breakage or bolt loosening. 6. Tighten hub sleeve bolts to 204 N·m (150 lb-ft) beginning with the center bolt in the lower sleeve, then criss-crossing the other bolts. Retighten bolts to 410 N·m (300 lb-ft) using the same sequence. Drive tractor a minimum of 100 meters (110 yd) and tighten bolts to 600 N·m (445 lb-ft). Retighten bolts after working 3 HOURS and again after 10 HOURS . Continue to tighten to specified torque daily during the first week of operation.
