Crankshaft and Bearing Installation
Crankshaft Bearing Installation Procedure
Tools Required
J 36660-A Torque/Angle Meter

Important: If the crankshaft bearings have been used in a running engine, you must replace them with NEW crankshaft bearings for reassembly.

Clean the upper and lower crankcase crank bore with a lint-free cloth.



Clean all the oil from the backside of new bearing halves.
Install new upper crankshaft bearings into position. The thrust bearing (1) belongs in the number three journal. Be sure the upper bearing insert contains the oil transfer hole and groove. Roll the bearing into position so that the lock tang engages the crank slot. The bearing must fit flush with the upper crankcase.



Install new lower crankshaft bearings into position in the lower crankcase. The lower crankcase crankshaft bearings are identified by NO grooves or holes. The bearings must fit flush with the lower crankcase.
Apply a liberal amount of GM crankshaft prelube GM P/N 1052367 or engine oil to the upper and lower bearing surfaces.
Crankshaft Installation Procedure




Install the crankshaft sprocket drive key (1). If necessary, lightly tap the key in place with a small hammer until it bottoms on the crankshaft.



Gently lower the crankshaft into position in the cylinder block.
Make sure the crankshaft turns without binding or noise.
Crankshaft Bearing Clearance Measurement Procedure
Place a length of fresh, room temperature plastic gaging material all the way across all the crankshaft bearing journals.



Align the lower crankcase with the dowel pins in the upper crankcase.
Install the lower crankcase onto the upper crankcase slowly until feeling a positive stop.
Inspect the upper-to-lower crankcase joint in order to make sure the lower crankcase is fully seated on the cylinder block.



Install the oil manifold plate.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the oil manifold plate retaining bolts.
Tighten
Tighten the oil manifold plate bolts to 10 N·m (89 lb in).





Place the crankshaft oil scraper in position on the oil manifold. Align the holes with the main bearing bolt holes.
Install the main bearing bolts. The single stud-head bolt (1) used for oil pump pick-up mounting goes in the inboard position of the third set of main bearing bolts from the front of the engine.



Install the left side upper-to-lower crankcase perimeter bolts.



Install the right side upper-to-lower crankcase perimeter bolts.



Tighten the lower crankcase bolts in proper sequence.
11.1. First Pass

Tighten
Tighten the lower crankcase bearing bolts (numbers 1 through 20) to 20 N·m (15 lb ft) in the proper sequence.

11.2. Final Pass

Tighten
Tighten the lower crankcase bolts (numbers 1 through 20) an additional 65 degrees in the proper sequence using the J 36660-A .





Tighten the upper-to-lower crankcase perimeter bolts (numbers 1 through 8).
Tighten
Tighten the upper-to-lower crankcase perimeter bolts (numbers 1 through 8) to 30 N·m (22 lb ft).

Allow the assembly to sit for at least two minutes.
Remove the main bearing bolts.
Remove the oil scraper.
Remove the oil manifold retaining bolts and oil manifold.
Remove the lower crankcase.



Determine the main bearing clearance by comparing the width of the flattened plastic gaging material at its widest point with the graduation on the gaging material container.
Compare your measurements with the engine mechanical specifications. If the new bearings do not provide the proper crankshaft to bearing clearance, re-measure the crankshaft journals for the correct specified size and check to make sure you have the correct new bearings. If the crankshaft journals are incorrectly sized, replace the crankshaft. No crankshaft machining is permitted and undersized bearings are not available.
Clean the plastic gaging material from the crankshaft bearings and/or crankshaft bearing journals using a soft lint-free cloth.
Coat the upper crankshaft bearings and crankshaft main bearing journals with GM crankshaft prelube GM P/N 1052367 or equivalent.


Reinstall the crankshaft into position in the cylinder block.

Piston, Connecting Rod, and Bearing Installation

Tools Required


• J 29789 Piston Ring Compressor

• J 39946 Crankshaft Socket - 4.0 L and 4.6 L

• J 36660-A Torque Angle Meter

Piston and Connecting Rod Assembly Procedure
Rotate the crankshaft using the J 39946 in order to align the crankshaft connecting rod journal being serviced to BDC.
Liberally lubricate the cylinder walls, piston rings and piston skirts with clean engine oil.
Important: Connecting rod bearings that have been used in a running engine, must be replaced with NEW connecting rod bearings for reassembly.


Select the correctly numbered piston/connecting rod assembly for the cylinder. An arrow showing proper piston orientation is located on the top of the piston.



Compress the piston rings using the J 29789 or equivalent.
Important: Extreme care must be exercised when installing the piston and connecting rod in order to be sure the rod does not scrape or nick the cylinder bore or the crankshaft surfaces.


Using both hands, slowly guide the piston and connecting rod assembly into the cylinder from the top and bottom of the cylinder. DO NOT allow the connecting rod to contact the cylinder wall.
When the piston ring compressor contacts the deck surface, gently tap the piston into the cylinder using the handle end of a dead-blow hammer. Guide the connecting rod onto the crankshaft bearing journal while taping the piston into the cylinder.
Connecting Rod Bearing Clearance Measurement Procedure
Important: Connecting rod bearings that have been used in a running engine, must be replaced with NEW connecting rod bearings for reassembly.


Before final assembly it is important to check the clearance of the new connecting rod bearings.
Place a length of fresh, room temperature plastic gaging material all the way across all the connecting rod bearing journal.



Install the connecting rod end cap on its original connecting rod making sure the bearing lock tangs are aligned on the same side of the rod.



When properly installed, the connecting rod bearing cap notches should be paired, as shown, on the crankpin.



Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Reuse the old connecting rod bolts ONLY for measuring the connecting rod bearing clearance.


Lubricate connecting rod bolts with engine oil and install in the connecting rod.

Tighten
Tighten the connecting rod bolts to 30 N·m (22 lb ft).

Loosen the connecting rod bolts until the torque reading is zero.
Re-tighten the connecting rod bolts.
First Pass

Tighten
Tighten the connecting rod bolts to 25 N·m (18 lb ft).

Final Pass

Tighten
Tighten the connecting rod bolts an additional 110 degrees using the J 36660-A .

Allow the assembly to sit for at least 2 minutes.



Remove the connecting rod cap bolts.
Remove the connecting rod cap.



Determine the connecting rod bearing clearance by comparing the width of the flattened plastic gaging material at its widest point with the graduation on the gauging material container.
Compare the measurements with the engine mechanical specifications. Refer to Engine Mechanical Specifications .
If the new bearings do not provide the proper crankshaft to bearing clearance, re-measure the crankshaft journals for the correct specified size and check to make sure you have the correct new bearings. If the crankshaft journals are incorrectly sized, replace the crankshaft. No crankshaft machining is permitted and undersized bearings are not available.
Clean the plastic gaging material from the connecting rod bearing and crankshaft connecting rod bearing journal using a soft lint-free cloth.
Connecting Rod Final Assembly Procedure
Back the connecting rod away from the crankshaft in order to allow for lubricant application.
Coat the crankshaft connecting rod bearing journal and installed connecting rod bearings with GM crankshaft prelube GM P/N United States 1052367, GM P/N Canada 992869, or equivalent.
Guide the connecting rod onto the crankshaft connecting rod bearing journal.



Install the connecting rod end cap on its original connecting rod making sure the bearing lock tangs are aligned on the same side of the rod.



When properly installed, the connecting rod bearing cap notches should be paired, as shown, on the crankpin.



Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: DO NOT reuse the old connecting rod bolts.


Lubricate the NEW connecting rod bolts with engine oil and install in the connecting rod.

Tighten
Tighten the NEW connecting rod bolts to 30 N·m (22 lb ft).

Loosen the connecting rod bolts until the torque reading is zero.
Re-tighten the connecting rod bolts.
First Pass

Tighten
Tighten the connecting rod bolts to 25 N·m (18 lb ft).

Final Pass

Tighten
Tighten the connecting rod bolts an additional 110 degrees using the J 36660-A .





During and after installation, check to make sure each piston is positioned properly in the correct cylinder. The locating arrow on the top each piston (1) must be pointing toward the front of the engine.
Repeat these procedures for the piston/connecting rod assembly that is using the common crankshaft connecting rod journal.
Measure the connecting rod side clearance between the two connecting rods that share the common crankshaft connecting rod journal.
Compare the measurements with the engine mechanical specifications. Refer to Engine Mechanical Specifications .
If the connecting rods do not provide the proper crankshaft side clearance inspect for the following conditions:
- If the clearance is too tight, ensure the connecting rods are not binding and can slide parallel to the crankpin. Re-measure the connecting rod widths for the correct specified size. If the connecting rods are incorrectly sized, replace the connecting rods.

- If the clearance is too loose, re-measure the connecting rod widths for the correct specified size. If the connecting rods are incorrectly sized, replace the connecting rods.

Repeat these procedures for the remaining piston/connecting rod assemblies using the J 39946 in order to rotate the crankshaft.

This next section uses a RTV that I have never seen aftermarket yet. The RTV is called TRIBOND EPOXY. Please read all the Notes. We have been using it for a couple of years and have seen NO LEAKS. It is the best stuff in the world. GM does not make it. I have used the remaining portion at a different time. This is so thick I use an AIR POWERED caulk gun. I have bent up two heavy duty guns. This will fix the common oil leaks found on the Northstars. This gets hard and brittle and it is used in gaps less than 1MM.

You do not need to use the alignment pins EN 46109. The block has built in pins. Make sure the REAR MAIN SEAL DRAIN BACK is clear of RTV. I have seen one rear main leak that had been replaced and I would guess that this was not done. I did not see the engine out of the car so I am not sure.

OK the bottom end is about done and this should have taken about 2hrs. I do not plastic gauge the engine. I do not use rebuilt parts or reground cranks. I have never repaired an engine with a lower end failure. This would mean that all my cranks and rods are good. Now lets move on to the heads

Camshaft Installation
Install the valve lifters with the flat surface facing up.



Clean the camshaft carriers with a clean, lint-free cloth.
Apply a liberal amount of clean engine oil to the carriers.
Place the camshaft in the camshaft carriers with the camshaft sprocket drive pins at the top of their rotation. The camshafts can be identified by a stamping near the rear journal. For example: L-EXH is defined as Left Bank Exhaust.



Install the camshaft bearing caps according to the identification marks. The arrow should point toward the front of the engine. The number indicates the position from the front of the engine and the I or E indicates intake or exhaust camshaft.
Hand start all the camshaft bearing cap bolts.



Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Tighten the left cylinder head camshaft bearing caps.

Tighten
Tighten the camshaft bearing cap bolts in sequence shown to 5 N·m + 30 degrees (44 lb in + 30 degrees).





Tighten the right cylinder head camshaft bearing caps.

Tighten
Tighten the camshaft bearing cap bolts in sequence shown to 5 N·m + 30 degrees (44 lb in + 30 degrees).

A cartridge type crankshaft rear main seal (Figure 1 - number 3) has been released for the 4.0L and 4.6L engines identified above. The cartridge type crankshaft rear main seal is identified by a metal flange located on the inner diameter of the seal which presses onto the crankshaft. The previous crankshaft rear main seal (Figure 1 - number 2) is a conventional lip type seal and has a soft rubber like material in the center where it contacts the crankshaft instead of this metal flange.

Important: The cartridge type crankshaft rear main seal is retained to the crankshaft with a press fit that requires over 45 kg (100 lb) of force to remove or install.

These high removal and installation forces make it necessary to remove the cartridge type crankshaft rear main seal with Kent-Moore Tool J 42841 (Figure 2) and install it with Kent-Moore Tool J 42842 (Figure 3). Refer to SI for Crankshaft Rear Oil Seal Replacement (Cartidge Type Seal) for instructions on the proper use of these tools. In addition, the cartridge type crankshaft rear main seal incorporates precise internal sealing surface relationships which are maintained for optimal sealing by using Kent-Moore installation tool J 42842.

DO NOT use Kent-Moore Tool J 38817-A (Figure 1 - number 1) to install the cartridge type crankshaft rear main seal. Attempting to install the cartridge type crankshaft rear main seal with Kent-Moore Tool J 38817-A will result in a damaged or improperly installed crankshaft rear main seal and will damage Kent-Moore Tool J 38817-A.

The cartridge type crankshaft rear main seal will be used to service 1996-1999 past model engines built after Engine Unit Number (EUN) T10L423109 which were installed in vehicles built after March, 1996.

This is not recommended by me, but is one way to prime the oil system.
Lubrication System Priming
After completing engine service requiring engine oil pump removal, you must perform the following procedures to prime the lubrication system before start up.

Verify that the engine oil is at the proper level. System capacity is 7 quarts with the oil filter full.
Fill the oil system to the proper level if necessary.
Disconnect the power lead connectors from the ignition modules.
Crank the engine for 30 seconds.
Reconnect the power lead to the ignition module.
Start the engine.
Check the DIC for a Low Oil Pressure message.
Listen for any audible engine noise such as lifters ticking.
If engine noises persist, stop the engine and remove the oil pressure sensor from the oil filter adapter.
Install an oil pressure gauge. Do not damage the threads in the adapter.
Start the engine.
• If oil pressure is indicated on the gauge and no unusual sounds are heard, oil pressure is present and both the oil pump and the engine lubrication system are primed.

• If no oil pressure is recorded, repeat from step 4 and then proceed the next step.

If no oil pressure is recorded after repeating the process, remove the oil filter adapter and force engine oil under pressure (using shop air) in the engine block outlet port (the port closest to the front of the engine).
Reinstall the oil filter adapter.
Restart the engine.
If oil pressure is obtained, stop the engine.
Reinstall the oil pressure sensor in the oil filter adapter.
Once the oil pressure sensor is connected, check the instrument display for a no oil pressure or low oil pressure message.
If a no oil pressure or low oil pressure message is present, check the switch connection. Repair the switch connection as necessary

Remember 10 to 20 minutes between the time you lay the bead of RTV and the end when the mains are final torqued. I get my perimeter bolt in one pile, I have my main bolts in another, and the little 10mm head bolts in another. One of the little bolts is slightly longer for the oil pump pick up and you can mark the location of the one main stud. This goes OK you need to stay on task. The only problems I have is when a main bolt breaks and then you have a mess. I have my torque wrench set and my Degree wheel set and marked. The mains sound like they are going to break, but they usually don't.
This stuff is thick. It also has lot numbers so GM can go back to the manufacture if they have a problem. This is a very High quality product.
