Reassembly
CYLINDER BLOCK:
REASSEMBLY
1. Fully air-blow the coolant and oil passages in the cylinder block, the cylinder bore, and the crankcase to remove any foreign material.
CAUTION: Use a goggles to protect your eye.
2. Install each plug to the cylinder block. (Only screwed-type plugs are shown in the figure.)
Apply liquid gasket. Use Genuine Ultra Grey RTV Silicone Sealant Part No. 999MP-AM003P or equivalent.
Replace the copper washers with new ones.
Tighten them as specified.
3. Install the main bearings and the thrust bearings.
a. Remove dust, dirt, and oil on the bearing mating surfaces of the cylinder block and the main bearing caps.
b. Install the thrust bearings to the both sides of the No. 3 journal housing on the cylinder block and main bearing caps
Install the thrust bearings with the oil groove facing the crankshaft arm (outside).
Install the thrust bearings with a protrusion in the center on the main bearing caps.
c. Install the main bearings paying attention to the direction.
- Install the one with oil holes onto the cylinder block and the one without oil holes onto the main bearing cap.
- Before installing the bearings, apply engine oil to the bearing surface (inside). Do not apply oil to the back surface, but thoroughly clean it.
- When installing, align the bearing stopper to the notch.
- Insure the oil holes on cylinder block and those on the corresponding bearing are aligned.
4. Install the pilot converter to the crankshaft.
Using a drift approximately 35 mm (1.38 inch) in outer diameter, drive the pilot converter until its front end contacts the crankshaft.
Press-fit the pilot converter with its chamfering side facing the crankshaft.
It is acceptable to install it without the engine stand.
5. Install the crankshaft to the cylinder block.
While turning the crankshaft by hand, check that it turns smoothly.
6. Install the main bearing caps.
Align the identification number to the journal position to install.
Install the upper side of the identification number facing the front of the engine. (The number shall be read correctly from the rear of the engine.)
Using a plastic hammer or similar tool, tap them lightly to seat them on the installation position.
7. Follow the steps to tighten each main bearing cap bolts.
a. Apply engine oil to threads and seating surface of bolts, and tighten all bolts temporarily.
b. Tighten main bearing cap bolt (M12) to .....36.3 to 42.1 Nm (3.7 to 4.3 kg-m, 27 to 31 ft. lbs.) in order of 1 to 10.
c. Tighten main bearing cap sub bolt (M9) to .....26.5 to 32.3 Nm (2.7 to 3.3 kg-m, 20 to 23 ft. lbs.) in order of 11 to 20.
d. Tighten main bearing cap bolt (M12) to .....40 to 45° degrees (ideal 40 degrees) in order of 1 to 10.
e. Tighten main bearing cap sub bolt (M9) to .....30 to 35° degrees (ideal 30 degrees) in order of 11 to 20.
f. Tighten side bolt (M10) to ......46.1 to 51.9 Nm (4.7 to 5.3 kg-m, 34 to 38 ft. lbs.) in order of 21 to 30.
g. Install cover of cylinder block left-rear side (next to starter motor housing).
CAUTION: Measure tighten angle in step "d" and "e" with angle wrench. Do not measure visually.
Rotate crankshaft by hands after bolts are tightened. Check if it rotates smoothly.
Check the crankshaft side clearance.
8. Install rear oil seal to oil seal retainer.
Tap until flattened with front edge of oil seal retainer. Do not damage or scratch outer circumference of oil seal.
Install new oil seal in the direction shown in the figure.
9. Install rear oil seal retainer.
Apply liquid gasket thoroughly to rear oil seal retainer. Use Genuine Ultra Grey RTV Silicone Sealant Part No. 999MP-AM003P or equivalent.
Grease is applied on lips of oil seal. Do not touch.
10. Install the piston to the connecting rod.
a. Using a snap ring pliers, install the snap ring to the grooves of the piston rear side.
Insert it fully into groove to install.
b. Install the piston to the connecting rod.
Using an industrial drier or similar tool, heat the piston until the piston pin can be pushed in by hand without excess force [approximately 60 to 70°C (140 to 158°F)]. From the front to the rear, insert the piston pin into the piston and the connecting rod.
Assemble so that the front mark on the piston crown and the oil holes and the cylinder No. on the connecting rod are positioned as shown in the figure.
c. Install the snap rings to the front of the piston. After installing, check that the connecting rod moves smoothly.
11. Using a piston ring expander, install the piston rings.
CAUTION: Be careful not to damage the piston.
Position each ring with the gap as shown in the figure, referring to the piston front mark.
Install the top ring and the second ring with the stamped surface facing upward.
Stamped mark :R (top ring)
:2R (second ring)
12. Install the connecting rod bearings to the connecting rod and the connecting rod cap.
When installing the connecting rod bearings, apply engine oil to the bearing surface (inside). Do not apply oil to the back surface, but thoroughly clean it.
When installing, align the connecting rod bearing stopper protrusion with the notch of the connecting rod to install.
Check the oil holes on the connecting rod and those on the corresponding bearing are aligned.
13. Install the piston and connecting rod assembly to the crankshaft.
- Position the crankshaft pin corresponding to the connecting rod to be installed onto the bottom dead center.
- Apply engine oil sufficiently to the cylinder bore, piston, and crankshaft pin.
- Match the cylinder position with the cylinder No. on the connecting rod to install.
- Using a piston ring compressor, install the piston with the front mark on the piston crown facing the front of the engine.
CAUTION: Be careful not to damage the crankshaft pin, resulting from an interference of the connecting rod big end.
14. Install the connecting rod cap.
Match the stamped cylinder number marks on the connecting rod with those on the cylinder cap to install.
15. Tighten the connecting rod nuts as follows:
a. Apply engine oil to the threads and seats of the connecting rod bolts and nuts.
b. Tighten nuts to.....13.7 to 15.7 Nm (1.4 to 1.6 kg-m, 10 to 12 ft. lbs.).
c. Put mating (with paint) on each nut and connecting rod cap, all in the same direction (when using a protractor).
d. Then all nuts 60 to 65 degrees clockwise [target: 60 degrees] (angle tightening).
CAUTION: Always use either an angle wrench or protractor. Avoid tightening based on visual check alone.
After tightening the nuts, make sure that the crankshaft rotates smoothly.
Check the connecting rod side clearance.
16. Install knock sensor.
Make sure that there is no foreign material on the cylinder block mating surface and the back surface of the knock sensor.
Install it with its connector facing the rear side.
Do not tighten the mounting bolts while holding the connector.
Make sure that the knock sensor does not interfere with other parts.
Install the sub-harness with its shorter branch line to the RH bank.
CAUTION :If any impact by dropping is applied to the knock sensor, replace it with new one.
17. Install followings in reverse order of removal.
18. Remove engine assembly from engine stand.
19. Install drive plate.
Align guide pin of crankshaft rear end with pin holes of each parts to install.
Install drive plate, reinforcement plate and pilot converter (if not installed in step 4) as shown in figure.
Using drift of 33 mm (1.30 inch), push pilot converter into the end.
Face chamfered or rounded edge side to crankshaft.
