Install lock and nut (1).4. Install case (9) in carrier (11) with bevel gear (10) toward the flat made in the flange of carrier (11).5. Install pinion shaft (4) and housing (3) into carrier (11). Use shims (5) to put pinion shaft (4) in alignment with bevel gear (10).6. Make adjustments to nut (12) and nut (7) until free movement (backlash) between bevel gear (10) and pinion shaft (4) is ... .007 to .014 in.(0.18 to 0.36 mm)7. Tighten nut (12) and nut (7) the same amount until the torque needed to turn pinion shaft (4) is ... 30 to 50 lb. in.(3 to 6 N m)If the nuts are turned the same amount, the free movement (backlash) will not change.8. Check free movement (backlash). If an adjustment is necessary, turn nut (12) and nut (7) the same amount, and in the same direction until the correct free movement (backlash) is given. If the nuts are turned the same amount and in the same direction, the bearing preload will not change.
