INSTALL CONNECTING ROD BEARING
Note
Apply oil to the inner surface of each connecting rod bearing (the surface which contacts the crankshaft), but not to the outer surface (the surface which contacts the connecting rod sub-assembly or connecting rod cap).
Install the connecting rod bearings to the connecting rod sub-assembly and connecting rod cap.
Using a vernier caliper, measure the distance between the connecting rod bearing cap edge and connecting rod bearing edge.
| Dimension A - B or B - A |
|---|

Note
Clean the backside of the connecting rod bearing and the connecting bearing surface of the connecting rod sub-assembly.
INSTALL CRANKSHAFT BEARING
Note
Apply oil to the inner surface of each crankshaft bearing (the surface which contacts the crankshaft), but not to the outer surface (the surface which contacts the crankshaft bearing cap or cylinder block sub-assembly).
When replacing a crankshaft bearing, also replace the corresponding crankshaft bearing or No. 2 crankshaft bearing.
Clean each main journal, crankshaft bearing and No. 2 crankshaft bearing.
Align the crankshaft bearing claw with the claw groove of the cylinder block sub-assembly, and push in the 5 crankshaft bearings to install them.
Note
Clean the contact surface of the crankshaft bearing and cylinder block sub-assembly.
Apply oil to the inner surface of each crankshaft bearing (the surface which contacts the crankshaft), but not to the outer surface (the surface which contacts the cylinder block sub-assembly).
Make sure both sides of the oil groove in the cylinder block sub-assembly are visible through the oil feed holes in the crankshaft bearing. Make sure the amount visible on each side of the holes is equal.
