5.Tighten the jam nut, if equipped, to the correct torque value against the differential case. See the Section 8. Figure 5.62. To complete the assembly of axles equipped with driver-controlled main differential locks, see the Section 6. REAR DIFFERENTIAL EXAMPLE HOLD THRUST SCREW IN POSITION. Air Shift Unit for the Inter-Axle Differential Lock (IAD) Air Applied and Spring Release Models, Standard 1. Inspect the shift shaft for damage. Use an emery cloth to remove any small damage. If necessary, replace the shift shaft. Figure 5.63. ADJUSTIG BOLT COLLAR JAM NUT FORK 2 Place the spring and the shift fork into position in the differential. The spring must touch the screw side of the differential. The boss on the fork must be toward the adjusting bolt. 3. Install the shift shaft so the smaller part of the shaft goes through the fork and the spring. MAINTENANCE MANUAL TIGHTEN JAM NUT TO CORRECT TORQUE VALVE. BOLT-ON IAD COVER SHIFT SHAFT SPRING O-RING PISTON Figure 5.62 CAPSCREW SCREW-IN IAD COVER Figure 5.63 Assembly and Installation 4. If removed, install the O-ring onto the piston. Apply axle lubricant to the O-ring. 5. Install the piston in the shift shaft. WARNING When you apply some silicone gasket materials, a small amount of acid vapor is present. To prevent serious personal injury, ensure that the work area is well-ventilated. Read the manufacturer’s instructions before using a silicone gasket material, then carefully follow the instructions. If a silicone gasket material gets into your eyes, follow the manufacturer’s emergency procedures. Have your eyes checked by a physician as soon as possible. 6.On flange-type cylinders, apply silicone gasket material onto the mounting surface of the cylinder. On threaded cylinders, apply a continuous 0.06-inch (1.5 mm) diameter bead of a flange sealant, Meritor part number 2297-D-7076, around the cylinder thread circumference. 7.Install the cylinder. On flange-type cylinders, install and tighten the capscrews 7-12 lb-ft (10-16 N.m). NOTE: The adjusting screw is set to the specified distance after the input shaft assembly is installed. El tornillo de ajuste debe ser montado con la distancia especificada después del eje del mecanismo de bloqueo estar instalado. 8.Install the adjusting bolt and the jam nut. Spring Applied and Air Release Models (Reverse Shift Systems) 1. Lubricate all the parts with axle lubricant. Figure 5.64.

Assembly and Installation 2. Inspect the shift shaft for damage. If necessary, replace the shift shaft. 3. If removed, install new O-rings in the groove in the shift shaft, into the groove in the shift cylinder and onto the piston. 4. Lubricate the bore of the shift cylinder with axle lubricant. 5. Install the piston in the shift cylinder. 6. Insert the shift shaft in the piston and shift cylinder assembly. 7. Install the small snap ring that fastens the piston in the shift shaft. 8. Install the spring in the piston bore. 9. Install the gasket so that the tab on the gasket is under the right capscrew bore. 10. Place the shift cover in the shift cylinder housing. Install two capscrews and washers to fasten the shift cover to the cylinder. 11. Install the assembly into the differential so that the shift shaft is in the bore of the shift fork. 12. Install the “E” clip onto the shift shaft slot in front of the shift fork. 13. Install the capscrews and washers that fasten the assembly to the differential case. Tighten the capscrews to 7-12 lb-ft (10-16 N.m). NOTE: The adjusting screw is set to the specified distance after the input shaft assembly is installed. 14. Install the adjusting bolt and jam nut. Assembly Input Shaft, Bearing Cage, Oil Pump and Inter-Axle Differential. 1. Apply axle lubricant to the parts as they are being assembled.

If removed, install the bearing cap in the input bearing cage. Use a press and a sleeve to install the cap into the cage. The cap is correctly installed when the bottom of the cap is fully seated in the cage bore 3. If removed, install a new oil seal into the input bearing cage. • For unitized pinion seals, look the unitized pinion seal installation procedure in this section and then proceed to Step 4. Figure5.66. • For all other seals, look the following instructions. INTEGRATED SEAL TRIPLE-LIP SEAL WITH POSE FEATURE RIPLE-LIP SEAL WITHOUT POSE FEATURE Figure 5.66 64 MAINTENANCE MANUAL
