Installation

NOTE:
- All parts to be installed must be perfectly clean.
- Be sure to oil crankshaft journals, journal bearings, thrust bearings, crankpins, connecting rod bearings, pistons, piston rings and cylinder bores.
- Journal bearings, bearing caps, connecting rods, rod bearings, rod bearing caps, pistons and piston rings are in combination sets. Do not disturb such combination and make sure that each part goes back to where it came from, when installing.





1. Install main bearings to cylinder block.
One of two halves of main bearing, has an oil groove. Install it to cylinder block, and the other half without oil groove to bearing cap.
Make sure that two halves are painted in the same color.





2. Install thrust bearings to cylinder block between No.2 and No.3 cylinders. Face oil groove sides to crank webs.
3. Install crankshaft to cylinder block.





4. Install bearing cap to cylinder block, making sure to point arrow mark (on each cap) to crankshaft pulley side. Fit them sequentially in ascending order, 1, 2, 3, 4 and 5, starting from pulley side.
After installing bearing cap stiffeners, tighten bearing cap bolts in such order as shown in image a little at a time and repeat it till they are tightened to specified torque.

Tightening Torque (a): 54 Nm (39.0 ft. lbs.)

NOTE: After tightening cap bolts, check to be sure that crankshaft rotates smoothly when turning it by 8.0 Nm (69.6 inch lbs.) torque or below.





5. Install new gasket and oil seal housing.
Do not reuse gasket removed in disassembly. Apply engine oil to oil seal lip before installation. Tighten housing bolts to specification.`

Tightening Torque (a): 11 Nm (96 inch lbs.)

NOTE:
- As there are 2 types of housing bolts, refer to image for their correct use.
- After installing oil seal housing, gasket edges might bulge out; if so, cut them off to make them flush with cylinder block and oil seal housing.

6. Install oil pump.





7. Install flywheel (M/T model) or drive plate (A/T model). Using special tool, lock flywheel or drive plate, and torque its bolts to specification.

Special Tool, or equivalent (A): 09924-17810

Tightening Torque
(a): 78 Nm (56.5 ft. lbs.) (Flywheel bolts)
(a): 95 Nm (69.0 ft. lbs.) (Drive plate bolts)

8. Install pistons and connecting rods.
9. Install oil pump strainer and oil pan.





10. Install cylinder head assembly to cylinder block.

NOTE:
- Tighten cylinder head bolts to specified torque. Whenever installing cylinder head to new cylinder block, use following procedure to tighten cylinder head bolts.
- Tighten cylinder head bolts to specified torque and loosen them once till tightening torque becomes "zero." And then torque them to specification again.

11. Install camshaft, crankshaft timing belt pulley, timing belt, crankshaft pulley, water pump pulley, etc.
12. Install clutch to flywheel (for M/T vehicle).





13. Install engine mountings and brackets.

Tightening Torque
(a): 55 Nm (40.0 ft. lbs.)
(b): 45 Nm (32.5 ft. lbs.)

14. Install engine assembly to vehicle.
