Using a press, install ring gear (14) in the axle shaft housing. Install the ring gear with the chamfered side down. As the ring gear is being pressed into the axle shaft housing, it will be necessary to tap four dowels (19) down along with the ring gear. After installation, the ring gear should be even or slightly below the machined surface of the axle shaft housing. The four dowels must be flush with the ring gear. 23. Put a thin coat of clean SAE 30 oil on the outer bearing cone on the end of the axle shaft and on the contact surfaces of the Duo-Cone seal on the end of the axle shaft and in the axle shaft housing.

NOTE: As a check for the correct assembly and adjustment, the rolling torque of the bevel gear group measured at the pinion shaft should be 1.8 to 3.6 N m (16 to 32 lb in) for new bearings and 0.9 to 1.8 N m (8 to 16 lb in) for used bearings. 30. Measure the backlash between bevel gear (15) and the pinion shaft. The backlash must be 0.30 + 0.12 - 0.10 mm (.011 + .005 - .004 in). Do this by placing a dial indicator (as shown) tangent to the spline, being sure the yoke or spline adapter is tight to the spline. 31. The following chart gives examples of backlash at the pinion shaft, by showing the different distances from the pinion centerline to the dial indicator: https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sis... 2020/3/23

If the backlash does not meet specifications, loosen one adjusting nut the same amount as the opposite adjusting nut is tightened. This will maintain the bearing preload. Illustration A 33. After the backlash and preload adjustments have been made, the tooth contact between pinion shaft and bevel gear (15) must then be checked. Do the procedure that follows: a. Put a small amount of Prussian blue, red lead or paint on three or four adjacent teeth of bevel gear (15). b. Rotate the pinion shaft several revolutions in one direction and then several revolutions in the opposite direction. Then turn the pinion shaft in one direction until the marked teeth can be seen. c. The correct area of tooth contact starts near the inside end of the teeth of bevel gear (15) and goes a maximum of 50% of the length of the teeth. See Illustration A for an example of the correct area of tooth contact. https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sis... 2020/3/23
