Kia Sorento: Crankshaft Reassembly
1. |
Install the main bearings.
Upper bearings have an oil groove of oil holes; Lower bearings
do not.
|
(1) |
Align the bearing claw with the claw groove of the cylinder
block, push in the 5 upper bearings(A).
|
(2) |
Align the bearing claw with the claw groove of the main bearing
cap, and push in the 5 lower bearings.
|
|
2. |
Install the thrust bearings.
Install the 2 thrust bearings(A) under the No.3 journal position of
the cylinder block with the oil grooves facing outward.
|
3. |
Install the oil jet (A).
Tightening torque :
24.5 ~ 29.4 N.m (2.5 ~ 3.0 kgf.m, 18.1 ~ 21.7 lb-ft)
|
|
4. |
Place the crankshaft(A) on the cylinder block.
|
5. |
Place the main bearing caps on cylinder block.
|
6. |
Install the main bearing cap bolts.
Always use new crankshaft main bearing cap bolts. Crankshaft
main bearing cap bolts are toque-to-yield bolts designed to
be permanently elongated beyond the state of elasticity when
torqued, so if the bolts are removed and reused, it may cause
the bolts to break or fail to maintain clamping force.
|
•
|
The main bearing cap bolts are tightened in 3 progressive
steps.
|
•
|
If any of the bearing cap bolts is broken ordeformed,
replace it.
|
|
(1) |
Apply a light coat of engine oil on the threads and under the
bearing cap bolts.
|
(2) |
Using the SST (09221-4A000), install and uniformly tighten the
10 bearing cap bolts, in several passes, in the sequence shown.
Tightening torque :
14.7 N.m (1.5 kgf.m, 10.8 lb-ft) + 27.5 ~ 31.4 N.m (2.8
~ 3.2 kgf.m, 20.3 ~ 23.1 lb-ft) + 120 ~ 125°
|
|
(3) |
Check that the crankshaft turns smoothly.
|
|
7. |
Check crankshaft end play.
|
8. |
Install piston and connecting rod assemblies.
(Refer to Cylinder Block - "Piston And Connecting Rod")
|
1.
Check the crankshaft bearing oil clearance.
(1)
To check main bearing-to-journal oil clearance, remove the main
caps and bearing ...
