2006 DODGE RAM SRT-10 lock

REMOVAL
1. Disconnect the battery cables.
2. Remove the cylinder head (Refer to 9 - ENGINE/CYLINDER HEAD - REMOVAL).
3. Remove the oil pan and suction tube (Refer to 9 - ENGINE/LUBRICATION/OILPA N - R E M O VA L ) .
4. Remove bolts and the block stiffener.
5. Using Miller Tool 7471-B crankshaft barring tool, rotate the crankshaft so all of the pistons are below TDC.
6. Before removing the piston(s) from the bore(s):
a. Remove any carbon ridge formations or deposits at the top of the bore witha dull scraper or soft wire brush.
b. If cylinder bore wear ridges are found, use a ridge reamer to cut the ridgefrom the bore. DO NOT remove
more metal than necessaryto remove the ridge.
7. Remove the J-jet cooling nozzles.
NOTE: If cylinders have ridges, the cylinders are oversize and will more than likely need boring.
8. Using a hammer and steel stamp, stamp the cylinder number in the top of eachpiston.Thefrontofthepiston
is identified by a stamping on the top of the piston. DO NOT stamp in the outside 5 mm (.197 in.) of the piston
diameter. DO NOT stamp over the piston pin.
9. Mark the connecting rod and cap with the corresponding cylinder numbers.
10. Remove the connecting rod bolts and rod caps. Use care so the cylinder bores and connecting rods are not
damaged.
11. Use a hammer handle or similar object to push the piston and connecting rod through the cylinder bore.
12. Store the piston/rod assemblies in a rack.
CLEANING—PISTON AND CONNECTING ROD
CAUTION: DO NOT use bead blast to clean the pistons. DO NOT clean the pistonsandrodsinanacidtank.
PISTON
Clean the pistons and pins in a suitable solvent, rinse in hot water and blowdry with compressed air. Soaking the
pistons over night will loosen most of the carbon build up. De-carbon the ringgrooveswithabrokenpistonringand
again clean the pistons in solvent. Rinse in hot water and blow dry with compressed air.
CONNECTING ROD
Clean the connecting rods in a suitable solvent, rinse in hot water and blowdry with compressed air.
INSPECTION
INSPECTION - PISTONS
PISTON SKIRT DIAMETER (MIN.)
101.775 mm (4.006 in. )
Inspect the pistons for damage and excessive wear. Check top of the piston,ring grooves, skirt and pin bore. Mea-
sure the piston skirt diameter. If the piston is out of limits, replace the piston.

INSPECTION - CONNECTING ROD
Inspect the connecting rod for damage and wear. The
I-Beam section of the connecting rod cannot have
dents or other damage. Damage to this part can
cause stress risers which will progress to breakage.
Measure the connecting rod pin bore (1). The maxi-
mum diameter is 40.042 mm (1.5765 inch), minimum
diameter is 40.019 mm (1.5756 inch). If out of limits,
replace the connecting rod.
INSTALLATION
1. Lubricate the cylinder bores with clean engine oil.
2. Generously lubricate the rings and piston skirts
with clean engine oil.
3. Orientate the rings on the piston (Refer to 9 -
ENGINE/ENGINE BLOCK/PISTON RINGS - STAN-
DARD PROCEDURE).
4. Compress the rings using a piston ring compressor
tool(1).Ifusingastrap-typeringcompressor,
make sure the inside end of the strap does not
hook on a ring gap and break the ring.
5. Bar the crankshaft so the rod journal for the piston
to be installed is at BDC(Bottom Dead Center).
6. Make sure the front of the piston is oriented prop-
erly according to the marking on the top of the pis-
ton and the connecting rod is oriented properly.
7. Position the piston and rod assemblyinto the cylinder bore with the front of the piston oriented properly accord-
ing to the stamping in the top of the piston. Use care when you install the piston and connecting rod so the
cylinder bore is not damaged. The long side of the connecting rod must be installed on the intake side of the
engine.
8. Push the piston into the bore until the top of the piston is approximately50 mm (2 inch) below the top of the
block. Carefully pull the connecting rod onto the crankshaft journal.
9. Use clean engine oil to lubricate the threads and under the heads of the connecting rod bolts.
10.For fractured/split type connecting rods,thelongendoftherodmustbeinstalledtowardstheintakesideof
the engine.

a. The connecting rod split/face mustface toward the same side as the piston notch feature on the skirt. The
split face will face toward the exhaust side of the engine if properly installed.
11. Install the rod cap and bolts to the connecting rod. Tighten the connecting rod bolts evenly in 3 steps.
Tighten the bolts to 30 Nꞏm (22 ft. lbs.) torque.
Tighten the bolts to 60 Nꞏm (44 ft. lbs.) torque.
Rotate 60° clockwise.
12. The crankshaft must rotate freely. Check for freedom of rotation as thecaps are installed. If the crankshaft does
not rotate freely, check the installation of the rod bearing and the bearingsize.
13. Measure the side clearance between the connecting rod and the crankshaft. DO NOT measure the clearance
between the cap and crankshaft.
14. Install J-jet piston cooling nozzles.
15. Install block stiffener. Torque to 43 Nꞏm (32 ft. lbs.).
16. Install the suction tube and oil pan (Refer to 9 - ENGINE/LUBRICATION/OIL PAN - INSTALLATION).
17. Install the cylinder head onto the engine (Refer to 9 - ENGINE/CYLINDERHEAD - INSTALLATION).
18. Install a new filter and fill the crankcase with new engine oil.Prefill the filter with clean oil.
19. Connect the battery negative cables and start engine.

LUBRICATION
DESCRIPTION
A gear driven gerotor type oil pump is mounted behind the front gear cover inthe lower right portion on the engine.
OPERATION
A gerotor style oil pump draws oil from the crankcase through the suction tube and delivers it through the block
where it enters the oil cooler cover and pressure regulator valve. When oilpressure exceeds 517 kPa (75 PSI), the
valve opens exposing the dump port, which routes excess oil back to the oil pump.
At the same time, oil is directed to a cast in passage in the oil cooler cover,leading to the oil cooler element. As the
oil travels through the element plates, it is cooled by engine coolant traveling past the outside of the plates. It is
then routed to the oil filter head and through a full flow oil filter. If a plugged filter is encountered, the filter by-pass
valve opens, allowing unfiltered oil to lubricate the engine. This condition can be avoided by frequent oil and filter
changes, per the maintenance schedules found in the owners manual. The by-pass valve is calibrated to open when
it sees a pressure drop of more than 345 kPa (50 psi) across the oil filter.
The oil filter head then divides the oil between the engine and the turbocharger. The turbocharger receives filtered,
cooled and pressurized oil through a supply line from the filter head. The oil lubricates the turbocharger and returns
to the pan by way of a drain tube connecting the bottom of the turbocharger toa tube in the cylinder block.

Oil is then carried across the block toan angle drilling which intersects the main oil rifle (3). The main oil rifle (3)
runs the length of the block and delivers oil to the crankshaft main journals and valve train. Oil travels to the crank-
shaft through a series of transfer drillings (one for each main bearing) and lubricates a groove in the main bearing
upper shell. From there another drilling feeds the camshaft main journals. J-jet piston cooling nozzles (1,4) are sup-
plied by a separate oil rifle. Plugs are used in place of saddle jets when J-jets are used. Crankshaft internal cross-
drillings supply oil to the connecting rod journals.
