Inspection |
1. |
Check the connecting rod end play.
Using a feeler gauge, measure the end play while moving the connecting rod back and forth.
|
2. |
Check the connecting road bearing oil clearance.
|
3. |
Inspect the connecting rods.
|
1. |
Check the crankshaft bearing oil clearance.
|
2. |
Check crankshaft end play.
Using a dial indicator, measure the thrust clearance while prying the crankshaft back and forth with a screwdriver.
If the end play is greater than maximum, replace the thrust bearings as a set.
|
3. |
Inspect main journals and crank pins.
Using a micrometer, measure the diameter of each main journal and crank pin.
|
1. |
Remove gasket material.
Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block. |
2. |
Clean cylinder block
Using a soft brush and solvent, thoroughly clean the cylinder block. |
3. |
Inspect top surface of cylinder block for flatness.
Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head gasket for warpage.
|
4. |
Inspect cylinder bore diameter.
Visually check the cylinder for vertical scratchs.
If deep scratches are present, replace the cylinder block. |
5. |
Inspect cylinder bore diameter.
Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial directions.
|
6. |
Check the cylinder bore size code on the cylinder block.
Cylinder Bore Inner Diameter
|
7. |
Check the piston size code on the piston top face.
H5 : HEV 2.4L
A : Grade
II : Theta II
Piston Outer Diameter
|
8. |
Select the piston related to cylinder bore class.
|
1. |
Clean piston
|
2. |
The standard measurement of the piston outside diameter is taken 17mm (0.67in.) from the bottom of the piston.
|
3. |
Calculate the difference between the cylinder bore diameter and the piston diameter.
|
4. |
Inspect the piston ring side clearance.
Using a feeler gauge, measure the clearance between new piston ring and the wall of the ring groove.
If the clearance is greater than maximum, replace the piston. |
5. |
Inspect piston ring end gap.
To measure the piston ring end gap, insert a piston ring into
the cylinder bore. Position the ring at right angles to the cylinder
wall by gently pressing it down with a piston. Measure the gap with a
feeler gauge. If the gap exceeds the service limit, replace the piston
ring. If the gap is too large, recheck the cylinder bore diameter
against the wear limits, If the bore is over the service limit, the
cylinder block must be replaced.
|
1. |
Measure the diameter of the piston pin.
|
2. |

|
3. |
Check the clearance between the piston pin diameter and the connecting rod small end diameter.
