3. Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings Chart
determine the required bearing grade for each main bearing.
zRead the first letter of the engine block main bearing code and the first letter of the
crankshaft main bearing code.
z Read down the column below the engine block main bearing code letter, and across the
row next to the crankshaft main bearing code letter, until the two intersect. This is the
required bearing grade for the number one crankshaft main bearing.
z As an example, if the engine block code letter is "F" and the crankshaft code letter is "D,"
the correct bearing grade for this main bearing is "2."
z Repeat this process for the remaining four main bearings.
4. If oversize bearings are being used, use the procedure in the previous step and the Bearing Select Fit Chart, Oversize Bearing Chart to determine the required grade for each main bearing. Klj . 3 ba

NOTE:
Before assembling the cylinder block, all sealing surfaces must be free from chips, dirt, paint
and foreign material. Also, make sure the coolant and oil passages are clear.
5. Install the upper main bearings into the cylinder block and the lower main bearing into the crankshaft main bearing caps. Lubricate the main bearings with clean engine oil.
6. Install the crankshaft into the cylinder block.
7. CAUTION: Make sure the coated side of the thrust washer with the 5- mm wide oil
grooves faces the crankshaft thrust surface.
Push the crankshaft rearward and install the crankshaft thrust washer at the back of the No. 5
main boss. Klj . 4 ba

CAUTION: Do not scratch the cylinder walls or crankshaft journals with the
connecting rod.
NOTE: Make sure that the piston arrow is facing forward.
NOTE: Lubricate the piston rings, cylinder walls and connecting rod bearings with clean engine
oil.
Using the special tool push the pistons through the top of the cylinder block.
14. CAUTION: Do not scratch the cylinder walls or the crankshaft journals with the
connecting rod.
NOTE: Make sure the crankshaft is at T.D.C.
Using the special tool, install the connecting rod assemblies.
15. NOTE: The rod bearing cap bolts are torque- to-yield. Install new bolts each time they are
serviced.
Install the connecting rod bearing caps and bolts and tighten in three stages.
zStage 1: tighten to 25 Nm (18 lb- ft).
z Stage 2: tighten to 45 Nm (33 lb- ft).
z Stage 3: tighten an additional 90 degrees. Klj . 7 ba

27. Install a retaining clip on the tensioner to hold the plunger in during installation.
28. Remove the tensioner from the vise.
29. If the copper links are not visible, mark two links on one end and one link on the other end, and
use as timing marks.
30. Install the timing chain guides.

position. Rotate the RH camshaft timing sprocket until the timing mark is at approximately 11
o'clock position.
32. CAUTION: Unless otherwise instructed, at no time when the timing chains are
removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated.
Severe piston and valve damage will occur.
CAUTION: Rotate the crankshaft counterclockwise only. Do not rotate past position
shown or severe piston and/or valve damage will occur.
Using the special tool, position the crankshaft.
zRemove the special tool.
33. Install the crankshaft sprocket with the flange facing forward.
34. Install the LH and RH timing chain onto the crankshaft sprocket, aligning the one copper (or marked) link on the timing chain with the slot on the crankshaft sprocket. Klj . 12 ba

80. Remove the engine from the stand.
81.
NOTE: If not secured within four minutes, the sealant must be removed and the sealing area
cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or four
minutes, whichever is longer. Failure to follow this procedure can result in future oil leakage.
Apply a 4 mm (0.16 in) bead of silicone gasket and sealant around the rear oil seal retainer
plate sealing surface. Also apply a bead of silicone gasket and sealant at the junction where the
cylinder block, oil pan and rear oil seal retainer plate meet.
82. Install the rear oil seal retainer plate. Tighten the bolts in the sequence shown. zTighten the bolts to 1- 6 to 10 Nm (89 lb-in).
z Hand- tighten bolts 7 and 8.
z Tighten bolts 7 and 8 to 20 Nm (15 lb- ft).
z Tighten bolts 7 and 8 an additional 60 degrees. Klj . 27 ba
