engine DODGE RAM SRT-10 2006 Service Repair Manual

INSTALLATION
1. Before installing piston and connecting rod assemblies into the bore, install the piston rings (Refer to 9 -
ENGINE/ENGINE BLOCK/PISTON RINGS - STANDARD PROCEDURE).
2. Immerse the piston head and rings in clean engine oil. Position a ring compressor over the piston and rings.
Tighten ring compressor.Ensure position of rings do not change during this operation.
3. Position bearing onto connecting rod. Lubricate bearing surface with clean engine oil.
4. Install Special Tool 8507 Connecting Rod Guides into connecting rod bolt threads.
5. The pistons are marked on the piston pin bore sur-
face with an raised “F” or arrow on top of piston
indicating installation position. This mark must be
pointing toward the front of engine on both cylinder
banks.
6. Wipe cylinder bore clean and lubricate with engine
oil.

COVER - STRUCTURAL
DESCRIPTION
The structural dust cover is made of die cast aluminum and joins the lower half of the transmission bell housing to
the engine.
OPERATION
The structural cover provides additional powertrain stiffness and reduces noise and vibration.
REMOVAL
1. Raise vehicle on hoist.
CAUTION: On manual transmission vehicles, the
7/16 inch engine block to clutch housing bolts
must be loosened before removal of the structural
dust cover (1). Clutch housing distortion will occur
if this procedure is not followed.
2. Remove the bolts retaining structural cover (1,2).
3. Remove the structural cover.

INSTALLATION
AUTOMATIC TRANSMISSION
CAUTION: The structural cover must be installed as described in the following steps. Failure to do so will
cause severe damage to the cover.
1. Position the structural cover in the vehicle.
2. Install all four bolts retaining the cover-to-engine. DO NOT tighten the bolts at this time.
3. Install the four cover-to-transmission bolts. Do NOT tighten at this time.
CAUTION: The structural cover must be held tightly against both the engineand the transmission bell hous-
ing during tightening sequence. Failure to do so may cause damage to the cover.
4. Torque the (4) structural dust cover bolts that go
intothetransmissionto6-11Nꞏm(50-100in.lbs.).
5. Torque the (4) structural dust cover bolts that go
into the engine block to 6-11 Nꞏm (50-100 in.lbs.).
6. Starting with the two rearcover-to-engine bolts,
tighten bolts (1) to 54 Nꞏm (40 ft. lbs.), then tighten
bolts(2)and(3)to54Nꞏm(40ft.lbs.)inthe
sequence shown.
7. Install the exhaust pipe on left hand exhaust manifold.
8. Tighten exhaust manifold-to-exhaust pipe retaining bolts to 20–26 Nꞏm(15–20 ft. lbs.).
MANUAL TRANSMISSION
CAUTION: The 7/16 inch engine block to clutch housing bolts must be loosened before removal/installation
of the structural dust cover. Clutch housing distortion will occur if thisprocedure is not followed.
