5. Install the differential into the housing. See<br />
the Section 5.<br />
6. Install and tighten the differential-to-housing<br />
capscrews to the specified torque.<br />
7. Install the right- and left-hand axle shafts.<br />
See the Section 5.<br />
NOTE:<br />
When the manual engaging capscrew is removed<br />
from the service position in the center<br />
of the DCDL actuator, the main differential<br />
lock is disengaged.<br />
8. Remove the long manual engaging capscrew<br />
from the center of either the fixed<br />
capscrew or Threaded DCDL..<br />
9. Clean the plug, gasket, cylinder cover and<br />
threaded service position hole in the center<br />
of the fixed capscrew DCDL cylinder cover,<br />
or in the center of the Threaded DCDL.<br />
10. Verify that the sealing gasket is under the<br />
head of the capscrew.<br />
11.Install the manual engaging capscrew into<br />
the DCDL storage hole in the fixed capscrew<br />
or the Threaded DCDL assembly.<br />
Figure 6.33 and Figure 6.34.<br />
A. On a fixed capscrew DCDL shift assembly,<br />
remove the short plug and gasket from the<br />
storage hole of the DCDL.<br />
Install the short plug and gasket into the service<br />
position hole in the center of the DCDL.<br />
Figure 6.33..<br />
B. On a Threaded DCDL shift assembly, install<br />
the short screw or plug into the storage hole<br />
located in the top of the Threaded DCDL<br />
shift assembly. Figure 6.34.<br />

12. Tighten the plug to 44-55 lb-ft (60-75 N m).<br />
Tighten the manual engaging capscrew to<br />
22-28 lb-ft (30-38 N m) for fixed capscrew<br />
DCDL style cylinders and to 7-11 lb-ft (10-<br />
15 N m) for Threaded DCDL type reverse<br />
shifters.<br />
13. Connect the vehicle air line to the differential<br />
lock actuator assembly.<br />
14. Install the electrical connection on the sensor<br />
switch located in the differential, below<br />
the actuator assembly.<br />
15. Remove the security support from under<br />
the drive axle.Lower the vehicle to the floor.<br />
16. Fill the axle with lubricant. See the Section 7.<br />
17. Proceed to Check the Differential Lock in<br />

1. Use a cleaning solvent and rags to clean<br />
the inside of the axle housing and the differential<br />
mounting surface. See the Section<br />
4.<br />
2. Check the axle housing for damage. If necessary,<br />
repair or replace the housing. See the<br />
Section 4.<br />
3. Check for loose studs in the differential<br />
mounting surface. Remove and replace the<br />
studs where required. Apply liquid adhesive<br />
to the holes. Install and tighten the stud to<br />
150-230 lb-ft (204-312 N m).<br />
4. Connect an air line to the main differential<br />
lock actuator Figure 6.33 assembly coupling.<br />
5. Supply 120 psi (827 kPa) regulated air pressure<br />
through the air line.<br />
6. Verify that the DCDL engaged.<br />
