Daewoo DE12T - Connecting Rod Bearing Clearance; Crank Shaft Bearing and Connection Rod Bearing; Main Bearing Clearance; Oil Clearance between Crankshaft and Bearing

3.2. 7. Crank shaft bearing and connection rod bearing
1) Visual check
•
Visually check the crankshaft bearing and connecting rod bearing for scores, uneven wear
or damage.
2) Oil clearance between crankshaft and bearing.
•
Main bearing clearance
Install the main bearing in the cylinder
block, tighten the bearing cap to spec-
ified torque, then measure the inside
diameter.
Compare the two values obtained
through measurement of main bear-
ing inside diameter with the outside
diameters of crankshaft journals to determine the oil clearance.

•
Connecting rod bearing clearance
Install the connecting rod bearing in
the connecting rod bearing cap, tight-
en the connecting rod cap bolts to the
specified torque, then measure the
inside diameter.
Compare the two values obtained
through measurement of connecting
rod bearing inside diameter with the
outside diameters of crankshaft pins
to determine the oil clearance.
