and indicate to side of one tooth on ring gear.
Move ring gear as far as it will go in one direction
before it moves the pinion.
"0" the dial on the indicator face.
Move the ring gear in the opposite direction until it
contacts the pinion gear and observe the dial face.
The reading should be 0.127 to 0.254 mm (0.005 to
0.010 inch) (for 10 stud wheel end axle), or 0.127
mm to 0.203 mm (0.005 to 0.008 inch) (for 12 stud
wheel end axle). Check the backlash at three
different locations around the gear. There should be
no more than 0.06 mm (0.003 inch) var iation
between readings.
A reading larger than 0.008 to 0.010 inch is corrected
by moving ring gear closer to pinion. A reading
smaller than 0.005 inch is corrected by moving the
ring gear away from the pinion. Move the ring gear by
loosening on adjusting ring and then tightening the
opposite adjusting ring the same amount. Both
adjusting rings must be moved the same amount.
