All vehicles
NOTE:
Left side shown, right side similar.
NOTE:
Do not discard the oil cooler cover bolts. They are self-tapping bolts and will be needed to cut the threads in the new oil cooler cover.
CAUTION:
In the event of a catastrophic engine failure, always install a new oil cooler cover assembly (with oil cooler). Foreign material cannot be removed from the oil cooler.
NOTE:
The oil cooler is replaced as an assembly.
CAUTION:
Do not pull on the wiring to remove the glow plug connector or damage may occur.
NOTE:
Only one glow plug connector shown.
NOTE:
RH side shown, LH side similar.
NOTE:
Mark the location of the stud bolts.
CAUTION:
To prevent engine damage, you must always install four new bolts when installing the vibration damper.
WARNING:
To avoid personal injury, support the vibration damper during mounting bolt removal. The damper can slide off the nose of the crankshaft very easily.
NOTE:
The production engine will not have a wear sleeve.
NOTE:
Mark the front of each drive rotor for correct reassembly orientation.
CAUTION:
To prevent engine damage, do not remove the rear primary crankshaft flange bolts under any circumstances. If the flange is removed and reinstalled, it will result in engine vibration and premature transmission component wear.
NOTE:
The drill bit used must be the appropriate size for the body dent puller used in the following step.
NOTE:
It will be necessary to alternate between the two holes, drilled in the previous step, to walk the seal out of the engine rear cover.
NOTE:
Production engines will not have wear sleeve.
Two-piece head tube
NOTE:
Some engines may have been updated with a new two-piece crankcase-to-head tube. If the crankcase-to-head tube has been updated it will have a hex head.
All vehicles
NOTE:
Do not remove the oil rail end plugs or acoustic wave attenuator port fitting. Service parts are not available to support the components.
One-piece head tube
NOTE:
The rings on the crankcase-to-head tube are to be used to pry the tube assembly from the branch tube assembly or the oil rail assembly.
Two-piece head tube
CAUTION:
Use care not to deform the lower crankcase-to-head tube during removal. If the tube is damaged, a new tube must be installed.
NOTE:
Use a shop towel and metal brake parts cleaner to remove the oil residue prior to removing.
All vehicles
CAUTION:
Do not attempt to apply battery voltage to the fuel injector or damage to the fuel injector will occur.
CAUTION:
Failure to account for all snap rings or pieces of snap rings prior to placing the vehicle back in service can cause engine damage. A missing snap ring can be ingested into the lube oil system causing severe engine damage.
CAUTION:
To prevent engine damage, do not use air tools to remove the fuel injectors. The snap ring that extracts the injector can dislodge and fall into the oil drain hole.
NOTE:
There is not any need to drain the fuel rail.
NOTE:
If engine coolant is found in the combustion chamber, it may be necessary to install a new injector sleeve. For additional information, refer to FUEL CHARGING & CONTROLS - 6.0L DIESEL
.
NOTE:
If a snap ring or piece of a snap ring is missing from the injector hold-down assembly, it must be located prior to removing the shop towels.
NOTE:
Mark the location of the valve bridges before removing.
CAUTION:
To prevent engine damage, keep the push rods in the order in which they were removed. Install all push rods back in their original positions.
CAUTION:
To prevent engine damage, keep the cam followers in the order in which they were removed. Install all cam followers back in their original positions.
NOTE:
Prior to removing any piston and connecting rod assemblies, it is recommended that piston protrusion be evaluated. This will help identify bent or twisted connecting rods.
CAUTION:
To prevent engine damage, remove the ridge prior to removing the rod and piston assemblies if evident from the top of the cylinder bore. This reduces the chance of piston ring land damage during removal.
CAUTION:
To prevent engine damage, do not remove the rear primary crankshaft flange bolts under any circumstances. If the flange is removed and reinstalled, it will result in engine vibration and premature transmission component wear.
CAUTION:
Do not knick or scratch the camshaft bearings with the camshaft lobes or engine damage will occur.
CAUTION:
This patch bolt is unique - do not substitute or engine damage can occur.
