Connect the air hose to the shift cylinder. Tighten the air hose to 22-30 lb-ft (30-40 Nm). 11. Install the remaining axle shaft into the axle housing and differential 12. Check the lubricant level in the axles and hubs where the axle shafts were removed. Add the correct type and amount of lubricant if necessary. See the Section 7. Previous Tandem Axle, with Driver-Controlled Main Differential Lock (DCDL — Bolt-On DCDL Shift Assembly) and with Inter-Axle Differential (IAD) Before Towing or Drive-Away 1. Park the vehicle on a level surface. Block the wheels to prevent the vehicle from rolling. 2. Apply the parking brake using the switch inside the cab of the vehicle. 3. Shift the transmission into neutral and start the vehicle’s engine. 4. Shift the DCDL to the unlocked or disengaged position using the switch inside the cab of the vehicle. The indicator light in the cab will go off. 5. Stop the engine. NOTE: Remove in this point, only axle shaft (s) show (s) in table AI, that will remain on the road when the vehicle is transported. 6. Remove the stud nuts or capscrews and the washers from the flange of the axle shaf. FIG- URE 11.4.

Remove the plug and gasket from the storage hole. Install the plug and gasket into the threaded hole in the center of the shift cylinder cover. Tighten to 15-25 lb-ft (20-35 Nm). Figure 11.5. 12. Lock or engage the main differential Cage using using one of the following methods: pressurized air method or manual engaging method 13. Lock or engage the main diferential cage using the pressurized air method. A. Install the manual engaging capscrew into the threaded hole in the center of the cylinder. Turn the capscrew to the right 3 or 5 laps. FIGURE 11.6. B. Shift the transmission into neutral and start the vehicle’s engine. Keep the engine idling to increase the air pressure in the system. Does not release the parking brake. C. Shift the main differential Cage to lock or engaged using the switch inside the cab the vheicle. When differential is locked, the indicator light in the cab will go on. • If the indicator light will go off a, turn manually the driveline or IAD until main differential Cage be locked and the indicator light will go on. NOTE: When the locking ring is completely engaged with the main differential Cage splines, the differential is locked and the driveline do not be rotate. Figure 11.7. D. While the differential is held locked position by air pressure, rotate the manual engaging capscrew to right until you feel resistance against the piston Stop to rotate the capscrew. E. Place the system switch lock of the main differential cage in the position unlocked or disengagedo. F. Stop the engine. Continue from step 15.
