Reassembly
1. Install cylinder block.
2. Install crankshaft.
Install the main bearings to the cylinder block and
the main bearing caps.
Be sure that they are positioned correctly.
Apply new engine oil to the upper and lower main
bearing faces.
NOTE: Do not apply engine oil to the bearing back faces.

8. Install oil pump assembly. Refer to “Oil Pump” in this
manual.
9. Install oil strainer and O-ring.
10. Install oil pipe and O-ring.
11. Install crankcase with oil pan.
1. Completely remove all residual sealant, lubricant
and moisture from the sealing surfaces. The
surfaces must be perfectly dry.
2. Apply a correct width bead of sealant (TB– 1207C
or its equivalent) to the contact surfaces of the
crankcase. There must be no gaps in the bead.
3. The oil pan must be installed within 5 minutes
after sealant application to prevent premature
hardening of sealant.
4. Tighten the bolts and nuts to the specified torque.
Torque : 10 Nꞏm (1.0 Kgꞏm/89 lb in)
