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.
Max Warp:
- L series - 0.20 mm
- KZ series - 0.10 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. Marking is stamped on the lower left side of the rear side of the cylinder block (L-series) or on the mating plane (KZ-series).
L series engines
KZ series motors
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, 2L-T:
- Marking "1" - 92.00-92.01 mm
- Marking "2" - 92.01 - 92.02 mm
- Marking "3" - 92.02 - 92.03 mm
Engine 3L and 1KZ-T:
- Marking "1" - 96.00-96.01 mm
- Marking "2" - 96.01 - 96.02 mm
- Marking "3" - 96.02 - 96.03 mm
Maximum allowable diameter:
- Engines 2L, 2L-T - 92.23 mm
- 3L and 1KZ-T engine - 96.23 mm
Repair, increased by 0.50 mm:
- Engines 2L, 2L-T - 92.73 mm
- 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.
7. (Only 1 KZ-T) Checking the main bearing bolts.
Measure the thread diameter of the bolt at several points along the length.
Nominal diameter - 13.5-14.0 mm
Minimum diameter - 12.6 mm
If the thread diameter is less than acceptable, replace the bolt.
8. Check the flow area in the jet of the block, clean if necessary.
