DODGE RAM SRT-10 2006 Service Repair Manual

6. Install rocker arm shaft and pushrods (Refer to 9 -
ENGINE/CYLINDER HEAD/ROCKER ARM /

lbs.) torque, using the rocker shaft torque
sequence.

(1), if used.

9. Install cylinder head cover (1).

10. Tighten cylinder head cover bolts and double
ended studs (Refer to 9 - ENGINE/CYLINDER
HEAD/CYLINDER HEAD COVER(S) - INSTALLA-
TION) .
11. Install spark plugs.
12. Install ignition coil on plug (2), and torque fasten-
ers (3) to 7 Nꞏm (62 in. lbs)
13. Install ignition coil connectors (4).
14. Install air intake resonator.
15. Install air cleaner assembly.
16. Connect negative battery cable.

ENGINE BLOCK
CLEANING
Thoroughly clean the oil pan and engine block gasket surfaces.
Use compressed air to clean out:
The galley at the oil filter adaptor hole.
The front and rear oil galley holes.
The feed holes for the crankshaft main bearings.
Once the block has been completely cleaned, apply Loctite PST pipe sealantwith Teflon 592 to the threads of the
front and rear oil galley plugs. Tighten the 1/4 inch NPT plugs to 20 Nꞏm (177in. lbs.) torque. Tighten the 3/8 inch
NPT plugs to 27 Nꞏm (240 in. lbs.) torque.
INSPECTION
1. It is mandatory to use a dial bore gauge to mea-
sure each cylinder bore diameter. To correctly
select the proper size piston, a cylinder bore
gauge, capable of reading in 0.003 mm (.0001 in.)
INCREMENTS is required. If a bore gauge is not
available, do not use an inside micrometer.
2. Measure the inside diameter of the cylinder bore at
three levels below top of bore. Start perpendicular
(across or at 90 degrees) to the axis of the crank-
shaft and then take two additional reading.
3. Measure the cylinder bore diameter crosswise to
the cylinder block near the top of the bore. Repeat
the measurement near the middle of the bore, then
repeat the measurement near the bottom of the
bore.
4. Determine taper by subtracting the smaller diame-
ter from the larger diameter.
5. Rotate measuring device 90° and repeat steps
above.
6. Determine out-of-roundness by comparing the dif-
ference between each measurement.
7. If cylinder bore taper does not exceed 0.025 mm (0.001 inch) and out-of-roundness does not exceed 0.015 mm
(0.0006 inch), the cylinder bore can be honed. If the cylinder bore taper orout- of-round condition exceeds these
maximum limits, the cylinder block must be replaced. A slight amount of taper always exists in the cylinder bore
after the engine has been in use for a period of time.

CAMSHAFT
REMOVAL
REMOVAL - CAMSHAFT CORE HOLE PLUG
CAUTION: Do not damage the rear surface of the camshaft or the core plug sealing surface, when removing
the core plug.
1. Remove the rear cam bearing core plug.
REMOVAL - CAMSHAFT
1. Remove the battery negative cable.
2. Remove the air cleaner assembly. (Refer to 9 -
ENGINE/AIR INTAKE SYSTEM - REMOVAL)
3. Drain coolant. (Refer to 7 - COOLING - STAN-
DARD PROCEDURE)
4. Remove the accessory drive belt. (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL)
5. Remove the generator.
6. Remove the A/C compressor, and set aside.
7. Remove the radiator (Refer to 7 - COOLING/EN-
GINE/RADIATOR - REMOVAL).
8. Remove intake manifold (Refer to 9 - ENGINE/
MANIFOLDS/INTAKE MANIFOLD - REMOVAL).
9. Remove cylinder head covers (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).

10. Remove both left and right cylinder heads (4)
(Refer to 9 - ENGINE/CYLINDER HEAD -
REMOVAL).
11. Remove the oil pan (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - REMOVAL).

12. Remove timing case cover (1) (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) -
REMOVAL).
13. Remove the oil pick up tube.
14. Remove the oil pump (Refer to 9 - ENGINE/LUBRICATION/OIL PUMP - REMOVAL).

15. Remove timing chain (2) (Refer to 9 - ENGINE/
VALVE TIMING/TIMING BELT/CHAIN AND
SPROCKETS - REMOVAL).
16. Remove camshaft tensioner/thrust plate assembly.
NOTE: Identify lifters to ensure installation in original location.
17. Remove the tappets (2) and retainer (1) assembly.

18. Install a long bolt into front of camshaft to aid in
removal of the camshaft. Remove camshaft, being
careful not to damage cam bearings with the cam
lobes.
INSPECTION
1. The cam bearings are not serviceable. Do not attempt to replace cam bearings for any reason.
INSTALLATION
INSTALLATION - CAMSHAFT CORE HOLE PLUG
1. Clean core hole in block.
NOTE: Do not apply adhesive to the new core hole plug. A new plug will have adhesive pre-applied.
2. Install a new core hole plug at the rear of camshaft, using suitable flat faced tool. The plug must be fully seated
on the cylinder block shoulder.

INSTALLATION - CAMSHAFT
CAUTION: 5.7L engines equipped with MDS uses a
unique camshaft for use with the Multi Displace-
ment System. When installing a new camshaft, the
replacement camshaft must be compatible with
the Multi Displacement System.
1. Lubricate camshaft lobes and camshaft bearing
journals and insert the camshaft (figure1).
2. Install camshaft Tensioner plate assembly. Tighten
bolts to 28 Nꞏm (250 in. lbs.) torque.
3. Install timing chain and sprockets (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT/CHAIN
AND SPROCKETS - INSTALLATION).
4. Measure camshaft end play (Refer to 9 - ENGINE -
SPECIFICATIONS). If not within limits install a new
thrust plate.
