Precautionary Statements
March‐16
Caution:
The 3.6L Pentastar Engine is NOT A FREE SPIN ENGINE. Care must be exercised during disassembly not to rotate the crankshaft or camshafts once the valvetrain chain assemblies have been altered in any manner.
Section
Sheet
Caution:
Do not lay cylinder heads on gasket sealing surfaces. The design of the Multi‐Layer Steel (MLS) cylinder head gasket will not seal properly if there are any imperfections on the cylinder head or engine block. Use only approved plastic type gasket removing tools when cleaning these surfaces. Warning:
Multi‐Layer Steel (MLS) head gaskets have very sharp edges that could cause personal injury if not handled carefully.
Note:
Multi‐Layer Steel gaskets require a scratch free sealing surface. 1. Remove all gasket materials from cylinder head and block using care not to gouge or scratch the aluminum sealing surfaces.
2. Non compressible debris such as oil, coolant, or RTV sealants not removed from bolt holes can cause the aluminum cylinder block to fracture when tightening fasteners. 3. Clean all cylinder head bolt holes in the engine block. Do not use any sealants or adhesives on fasteners, Multi Layer Gaskets, or any sealing surfaces unless specified in this procedure. Surfaces must be debris free and scratch free for proper sealing.
Notes:
NOT A FREE SPIN ENGINE
Valve to Piston interference will occur if not properly disassembled / assembled

Cylinder Head Core Preparation
March‐16
New engines are ordered through Chrysler MOPAR under special order part number. Engines are preserved under long term packaging. Once received at the test laboratory, they should be disassembled and put into storage for future build. Cylinder heads should be completely disassembled and the valvetrain gear stored for future use. Section
Sheet
Bare cylinder heads (Cores)should be sent to IMTS for re‐
work. Labs must use the IMTS Special Packaging to protect the cores from damage. Packaging contains special cushioning sleeves for both Right and Left cylinder heads.
1. Camshaft caps are identified on the sides, "1E‐> , 2E‐>" etc. for exhaust camshafts and "1I‐> , 2I‐>" etc. for intake camshaft caps. Caps must be kept in order.
2. Remove all valvetrain hardware from cylinder heads; camshafts, roller rockers, lash adjusters, valve springs, valve seals, and spark plugs.
3. Keep all camshaft bearing caps in order. Replace after valvetrain hardware removal. Do not use air or battery powered tools to tighten camshaft caps. Use a speed handle to lightly snug fasteners and torque M6 T30 fasteners to 9.5 Nm.
4 After removing all valvetrain gear and torqueing all camshaft caps in their proper position, install the cylinder head in VCI bag and insert the assembly in the IMTS Packaging with proper inserts, Securely tape package and ship to: IMTS 8460 Ronda Dr.

1. After disassembly and modification of the main oil gallery, technicians should carefully clean all RTV from mating surfaces using care to avoid scratching or gouging any mating surfaces. Spray degreasing solvent through all oil gallery passages from the underside through the piston cooling jet access holes to clean any debris from galleries.
Caution:
Technicians should exercise extreme caution while cleaning mating surfaces of the engine block. Use only plastic type non marring scrapers for removal of RTV and other debris from mating surfaces. Visual imperfections on the cylinder deck and other gasket sealing areas may remain even after removing RTV. 2. If desired, chase all threaded bolt holes for the cylinder head bolt holes and the main cap bolt holes using cleaning thread chase taps. Avoid using thread cutting type taps to clean threads. Thread cleaning taps are
available through sources such as ARP, Snap‐on, or Mac Tools for SAE and Metric thread sizes.
Caution:
Non compressible debris such as oil, coolant, or RTV sealants not removed from bolt holes can cause the aluminum cylinder block to fracture when tightening fasteners. 3. Clean the engine block prior to honing using either of the following methods;
a. Clean in the spray booth using degreasing solvent followed by a 50/50 solution of EF‐411 and Degreasing Solvent
followed by air dry using clean dry compressed shop air.
b. Clean using the Ultra Sonic Cleaner following the manufacturers recommendations followed by a water rinse
and spray with a 50/50 solution of EF‐411 and Degreasing Solvent followed by air dry using clean compressed air.
Note:
If cleaning the block in the Ultra Sonic Cleaner, install M12 x 1.5 50mm long bolts with M12 nylon oil drain plug type
washers snugly into the cylinder head bores to prevent the Ultra Sonic Cleaner solution from leaching out the lubricant on the threads in the block to prevent bolt chatter during the cylinder head fastener torquing procedure.
4. Clean and inspect the cylinder head fasteners from the New Engine Disassembly.
5. Lightly oil the cylinder head fasteners with EF‐411 and allow to drain all excess oil from the threads using clean
Teri towels before installation of cylinder torque plates.
6. Clean and lightly oil the main cap fasteners and side bolts using EF‐411 allowing all excess oil to drain from the threads using clean Teri towels.
7. Cylinder head gaskets are Multi‐Layer Steel gaskets. The cylinder head gaskets removed during the New Engine
disassembly can be re‐used with the BHJ Torque Plates and spacers used to position the fasteners at the correct
bolt drop in the cylinder block. 8. A good practice for build technicians is to ensure there is no oil or debris in the blind threaded bolt holes before
assembling the main caps or cylinder block torque plates using compressed air or blotting with absorbent materials.
Note:
Technicians should prep the cylinder head fasteners and the main cap fasteners prior to installation by wiping the
threads between folded sections of an EF‐411 saturated "Lint Free" rag during fastener installation.
See the materials section of the IIIH Engine Assembly Manual for suggested supplier information on Lint Free Rags that have been found suitable for use by the test labs.

16. Install the diamond stones in the Sunnen SV‐10 Hone Head.
17. Set Zero Cut Off Mode to “ON” with the Auto Finish “OFF”.
Note: The Auto Finish is set to “OFF” during these first operations to keep the honer from running an extra “Six Cycles” during the bore straightening process if the machine were to dwell just before the Zero Cut Off.
18. Insert the hone head into the first cylinder on the right bank. Cylinder #1
19. Using the Crown Wheel on the Hone, tighten the hone head until the diamond stones lightly contact the cylinder wall
using a rocking motion to ensure the stones are fully contacting the cylinder.
Note: Each Technician must acquire the feel for when the stones are fully engaged without putting Too Much Pressure
on the stones as to simulate a high unit loading.
20. With the instruction in line item 19 complete, set the Lower Crown Ring on the Hone Head to Zero Cut Off.
21. Set the lower ring to three divisions from Zero Cut Off.
22. Start the hone and flood the cylinder with honing fluid.
Note: The honing fluid flow should be set at 7L/min.
23. Engage the hone and rapidly put 30 units load on the stones.
24. Immediately set the lower ring to 1 division (or slightly less) before Zero Cut Off.
Note: Line item instruction 21 is set to three divisions to keep the hone from shutting off while putting the load on the hone head. Operators should immediately perform line item instruction 24, after setting the initial load on the hone head to 1 division before Zero Cut Off, to prevent the hone from removing too much material during the cylinder straightening process. 25. Allow the hone to run to the shut off position without adjusting the hone head pressure.
Note: The hone will drop off on the load and dwell as necessary throughout this operation at Top, Middle, and Bottom
positions to auto straighten the cylinder bore and shut off automatically at the zero shut off point.
26. Repeat steps 21 through 25 for each cylinder following the proper sequence (Cylinder 1 – 5 – 4 – 3 – 2 – 6).
27. Upon completion of the first pass through all six cylinders, let the block cool for a minimum time period of 15 minutes.

28. Set the Auto Finish to “ON”.
29. Measure all cylinders bore transverse and longitudinal dimensions.
30. Repeat the same process as needed based on the cylinder bore dimensions, for each cylinder in sequence while
setting the lower ring to one half of a division before the Zero Cut Off.
Note: This time the machine will run an additional six cycles if it dwells just prior to Zero Cut Off which will keep the cross hatch pattern.
Note: The Technician must put their trust in the SV‐10 to straighten the bore!
At this point the bores will be ~ 10 to 15 micron (0.010mm to 0.015mm) undersize after the block cools down.
31. Set the honer to Timed Cycles, and ensure the Auto Dwell and Auto Finish are set to “OFF” on both controls.
32. Hone each cylinder in proper sequence ~ 8 to 10 strokes with the Diamond Stones at 30 to 40 units load.
Note: Each Technician needs to acquire the feel for the amount of material removed during this process and adjust
the time to target mid spec. on the bore diameter. This may take more or less strokes to reach mid spec. Each Technician needs to understand how much load on the hone head is required to meet the surface finish specifications based on their hone and fluid interaction, i.e., this means they may require more or less load. 33. Once the Technician is satisfied the bore is at mid spec, the technician should switch the Diamond Stones out replacing them with the Plateau Brushes.
34. Following the cylinder sequencing, cycle the Plateau Brushes for six to ten strokes in each cylinder at 10 to 15 units load.
Note: Each Technician needs to acquire the feel for their hone and fluid condition which will establish the required stroke and unit loading to meet the final surface finish specifications.

The cylinder block is a 60 degree high‐pressure die cast aluminum design with cast steel cylinder liners. The leading side of the block is on the right side and houses cylinders 1, 3 and 5. The cylinder block is an open deck design with cut slots between each cylinder. Two knock sensors are located in the block valley. The cylinder block has three sets of piston cooling jets which are attached to the main oil gallery. The four powdered metal main bearing caps are a cross‐bolted design and have directional arrows molded into the caps. The number 2 main bearing is the location for the two piece upper half thrust
bearings. The thrust bearings are installed with the oil groves facing outward. The main bearing caps are a 6‐
bolt design and cross‐bolted for improved lower end strength. There are three oil drain back drillings located on Blocks and crankshafts are precision measured during manufacture and marked with specific bore and journal size identifications. Bearing shells are manufactured to provide select fit clearances based on these measurements. Note:
Engines should be kept with their respective parts as select fit clearances will differ between each engine. Clearances may be confirmed through actual measurements with reference to the following bearing selection charts and identification markings on the block and crankshaft. See Section 5 Sheet 2
Note:
Crankshaft thrust washers are not selectable and are only available in single thickness.
Caution:
Main bearing fasteners are snug torque plus angle tightening. Main bearing fasteners are Not Yield Fasteners. Main bearing fasteners have been torqued twice during manufacture. Labs should strive to minimize the number of torque applications during test build. If threads in the block are pulled during assembly, the labs are allowed to use thread inserts, however, labs must understand the main caps are positioned through the shoulder of the fastener and threaded inserts could cause misalignment. Note:
Main Bearing cap bolts are replaced as necessary.
Cylinder head bolts are reused for torque plate application during honing.
Cylinder head bolts are replaced with new fasteners for test build.
Connecting rod cap bolts are replaced for test build.
All reused fasteners should be checked for necking before use.

Piston Ring Gap / Piston Cooling Jets
Piston Ring Gap Measurement:
Position the top and second piston rings ~ 1 inch down from the top of the bore. Using a Starrett Taper Gage Model 270, measure the gap and record the pre‐test measurement on the appropriate engine build data form. Note: Labs perform all ring gap measurements with the BHJ Torque Plates still installed on the engine. This view is for illustration only.
Cylinder Bore Cleaning:
Because the piston cooling jets protrude into
the bottom of the cylinder bore, technicians
should consider cleaning the cylinder bores
and oiling them for piston installation before
piston cooling jet installation.
Clean the cylinder bores with clean lint free terry
towels using EF‐411 to ensure cylinder bores are clean and debris free for continued assembly.
Piston Cooling Jets:
Lubricate the O‐ring on the piston cooling jet with EF‐
411 engine assembly lube. Install the piston cooling jet and torque the fastener
to 6 N∙m (53 in. lbs.).
Piston cooling jets are targeted during manufacture.
Care should be exercised not to damage or bend the
nozzle during handling.
Piston cooling jets have a check valve which closes
below 2.5 bar (35 psi). Piston cooling jets should be
replaced every test.

Oil Gallery Plugs

Oil Gallery threaded holes are straight thread. Oil gallery threaded plugs are taper pipe thread. These plugs are installed
at the factory using a pre‐snug value plus a very large number of degrees rotation to drive the tapered thread into the
straight thread. These plugs also use a special thread sealant. When removed the same installation specifications
cannot be used for re‐installation. Build Technicians must acquire a feel for obtaining the proper torque on the main oil gallery plugs and fittings used
for pressure taps and temperature thermocouples in the main oil gallery.
Recommended sealants for these operations are;
Threaded Gallery Plugs: Loctite 545, Loctite 567, Loctite #2 (Permatex #2), Teflon Tape
Caution: When applying sealants, technicians should try to keep the sealants away from the first two threads of
the plug or thermocouple fitting to keep sealants from rolling over the threads and into the oil gallery.
Caution: By direction of the Task Force governing body during the Precision Matrix, it was decided to stop
removing the front main oil gallery cup plug. Labs are currently not to be removing this gallery plug. If a lab has a block with the plug removed or needs to re‐install a cup plug, the recommended sealant is;
Loctite 648 Retaining Compound 04556020AB Plug, Cup, Front Oil Gallery
When installing the front cup plug, use a properly
sized driver and install the cup plug until the front
edge is 1mm deep from the front face of the block or
beyond the chamfered edge of the gallery.
Install the side and rear oil gallery plugs as required
for test operations.
Install the main oil gallery thermocouple
fitting using lab preference sealing compounds
Note: Labs must use calibrated thermocouples for the
specific test cell / instrumentation calibration.
Recommended fitting:
Swagelok Tube Fitting SS‐200‐1‐1BT
1/8" Tube O.D. x 1/16 Male NPT
Use IMTS 151132‐F002 Thermocouple Setting
Fixture to position the tip of the main oil
gallery thermocouple in the center of the gallery. Engineering Recommendation:
Some labs have experienced oil leaks at the main oil gallery thermocouple fitting.
Leaks may be related to 50/50 EF‐411 in the threads from the cleaning process.
Cleaning the threads with a non‐lubricated type contact cleaner has been found to help.
Air dry all residue from any cleaning products and inspect main oil gallery for any residues from cleaners or sealants after installing the thermocouple.
