If necessary, follow Step 7.a through Step 7.g in order to remove manifold (5) and tube assemblies from the NOx reduction system (NRS) manifold.
Remove plastic breather tube from the crankcase breather cannister and the valve mechanism cover. Refer to Disassembly and Assembly, "Crankcase Breather- Remove" for the correct procedure.
Remove bolt (13) from tube assembly (15). Remove bolt (14) from clip for the tube assembly. Loosen hose clamp (16) from the hose for tube assembly (15).
Remove tube assembly (15) from manifold (5) and the NRS manifold. Remove O-ring seal (12) (not shown).
Remove bolt (17) from tube assembly (19). Remove bolt (20) from clip for the tube assembly. Loosen hose clamp (25) from hose for tube assembly (19).
Remove tube assembly (19) from manifold (5) and the NRS manifold. Remove O-ring seal (18) (not shown).
If necessary, remove connection (21) and connection (25) from the NRS manifold.
Cut cable strap (23) from harness assemblies. Remove bolts (24) from manifold (5). Remove manifold (5) from the inlet elbow. Installation Procedure
Ensure that wiring harness are correctly routed and the cable straps are not over tightened. Over tightening of the cable straps will damage the wiring harness convoluting.
Ensure that all components are clean and free from wear and damage. If necessary, replace any components that are worn or damaged. Ensure that all tube assemblies are clean and free from restriction.
