2. Clean the cylinder block using a soft brush and solvent.
3. Check up warpage of a plane of a socket of the block of cylinders with a head of the block.
- Maximum warping - 0.20 mm
If warpage exceeds the maximum allowable value, replace the cylinder block.
4. Check the cylinder mirror for vertical marks.
If there are deep risks, then squander all four cylinders. If necessary, replace the cylinder block.
5. Cylinder diameter control.
Note: There are three standard cylinder diameter sizes marked "1", "2" And "3" respectively. The marking is applied by branding in the lower left part of the rear side of the cylinder block.
Using a bore gauge, determine the diameter of the cylinder at positions A, B and C in the axial and transverse directions.
Nominal diameter:
Engines 2L
- marking "1" - 92.00 -92.01 mm
- marking "2" - 92.01 - 92.02 mm
- marking "3" - 92.02 - 92.03 mm
Engine 3L
- marking "1" - 96.00 -96.01 mm
- marking "2" - 96.01 - 96.02 mm
- marking "3" - 96.02 - 96.03 mm
Maximum allowable diameter:
- 2L engines - 92.23mm
- 3L engine - 96.23mm
Repair, increased by 0.50 mm:
- 2L engines - 92.73mm
- 3L engine - 96.73mm
If the diameter exceeds the maximum allowable value, bore all four cylinders. If necessary, replace the cylinder block.
6. Removing the wear groove.
If the wear does not exceed 0.2 mm, then use a reamer to remove the groove in the top of the cylinder.
