NOTE:
Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.
NOTE:
During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE:
For additional information, refer to the exploded views under the Engine Assembly procedure in this service information.

WARNING:
The clutch disc and clutch pressure plate are heavy and may fall if not held when the bolts are removed. Failure to follow this instruction may result in serious personal injury.
NOTE:
Loosen the 6 bolts evenly to prevent pressure plate damage.
NOTE:
If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
NOTE:
When removing the ignition coil-on-plugs, a slight twisting motion will break the seal and ease removal.
NOTE:
Failure to position the No. 1 position at Top Dead Center (TDC) can result in damage to the engine. Turn the engine in the normal direction of rotation only.
NOTE:
The Camshaft Alignment Plate is for camshaft alignment only. Using this to prevent engine rotation can result in engine damage.
NOTE:
The camshaft timing slots are offset. If the Camshaft Alignment Plate cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.
NOTE:
The Crankshaft TDC Timing Peg will contact the crankshaft and prevent it from turning past TDC. However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC position during disassembly.
NOTE:
The crankshaft must remain in the Top Dead Center (TDC) position during removal of the pulley bolt or damage to the engine can occur. Therefore, the crankshaft pulley must be held in place with the Crankshaft Damper Holding Tool and the bolt should be removed using an air impact wrench (1/2-in drive minimum).
NOTE:
The crankshaft sprocket diamond washer may come off with the crankshaft pulley. The diamond washer must be replaced, remove and discard the diamond washer. If the diamond washer is not installed, engine damage may occur.
NOTE:
Use care not to damage the engine front cover or the crankshaft when removing the seal.
NOTE:
The Camshaft Alignment Plate is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
NOTE:
The Camshaft Alignment Plate is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
NOTE:
Remove and discard the crankshaft sprocket diamond washer located behind the crankshaft sprocket.
NOTE:
The oil pump chain sprocket must be held in place.
NOTE:
Failure to follow the camshaft loosening procedure can result in damage to the camshafts.
NOTE:
Mark the location and orientation of each camshaft bearing cap.
NOTE:
If the camshafts and valve tappets are to be reused, mark the location of the valve tappets to make sure they are assembled in their original positions.
NOTE:
The number on the valve tappets only reflects the digits that follow the decimal. For example, a tappet with the number 0.650 has the thickness of 3.650 mm.
NOTE:
Due to the precision interior construction of the balancer unit, it should not be disassembled.
NOTE:
Clearly mark the connecting rods, connecting rod caps and connecting rod bearings in numerical order for correct orientation for reassembly.
NOTE:
Do not scratch the cylinder walls or crankshaft journals with the connecting rod.
NOTE:
If the main bearings are being reused, mark them in order for correct orientation and reassembly.
NOTE:
If the main bearings are being reused, mark them in order for correct orientation and reassembly.
NOTE:
The center bulkhead has the thrust bearing.
NOTE:
If the oil squirters are being reused, mark them in order for correct location during reassembly.
NOTE:
The front bulkhead does not have an oil squirter.
