Cylinder Heads
Installation (cont'd)
4. Install the cylinder heads on the cylinder block.
5. Tighten the cylinder head bolts sequentially in 2 or
3 steps.
Specified Torque:
76 N-m (7.8 kgf-m, 56 Ibf-ft)
NOTE:
We recommend using a beam-type torque wrench.
When using a preset-type torque wrench, be sure
to tighten slowly and not to overtighten.
If a bolt makes any noise while you are torquing
it, loosen the bolt and retighten it.

6. Install the head cover gasket in the groove of the
cylinder head cover. Seat the recesses for the cam-
shaft first, then work it into the groove around the
outside edges.
NOTE:
Before installing the cylinder head cover gasket,
thoroughly clean the seal and the groove.
When installing, make sure the head cover gasket
is seated securely in the corners of the recesses
with no gap.

7. Apply liquid gasket to the head cover gasket at the
four corners of the recesses.
NOTE:
Use liquid gasket, Part No. 08718 - 0001 or 08718
- 0003.
Check that the mating surfaces are clean and dry
before applying liquid gasket.
Do not install the parts if five minutes or more have
elapsed since applying liquid gasket. Instead, reap-
ply liquid gasket after removing old residue.
After assembly, wait at least 30 minutes before
filling the engine with oil.

Pistons and Crankshaft
Removal (cont'd)
11. Remove the bearing from the cap. Keep all caps/bear-
ings in order.
12. Remove the upper bearing halves from the connecting
rods, and set them aside with their respective caps.
13. After removing each piston/connecting rod assem-
bly, reinstall the cap on the rod.
14. To avoid mixup during reassembly, mark each pis-
ton/connecting rod assembly with its cylinder num-
ber.
NOTE: The existing number on the connecting rod
does not indicate its position in the engine, it indicates
the rod bore size.
15. Remove the bearing cap bolts and bearing cap side
bolts, then remove the bearing cap.
