Installation Procedure

1. Install the spacer plate gasket and the spacer plate. Refer to Disassembly and Assembly, "Spacer Plate - Remove and Install".

   Note: Ensure that all surfaces are clean and dry when the spacer plate gasket is installed.

2. Clean the cylinder liner and the cylinder bore in the cylinder block.

3. Position the cylinder liner in the cylinder bore without the seals or the filler band.

4. Use the following steps to check the cylinder liner projection:

   1. Install four bolts (4) and the washers from Tooling (A). Tighten the bolts evenly in four steps.

      Step 1 ... 14 N·m (10 lb ft)

      Step 2 ... 35 N·m (25 lb ft)

      Step 3 ... 70 N·m (50 lb ft)

      Step 4 ... 95 N·m (70 lb ft)

   2. Install crossbar (2), plates (3), and bolts (1) from Tooling (A). Ensure that crossbar (2) is in position at the center of the cylinder liner. Also ensure that the surface of the cylinder liner is clean. Tighten bolts (1) evenly in four steps.

      Step 1 ... 7 N·m (5 lb ft)

      Step 2 ... 20 N·m (15 lb ft)

      Step 3 ... 35 N·m (25 lb ft)

      Step 4 ... 70 N·m (50 lb ft)

   3. Check the distance from the bottom of crossblock (2) to the top of the spacer plate. The distance at both ends of the crossbar must be equal.

   4. Check the liner projection with Tooling (B) at four locations on the cylinder liner. The cylinder liner projection must be 0.129 ± 0.070 mm (0.0051 ± 0.0028 inch). A distance of 0.05 mm (0.002 inch) must be the maximum difference between the measurements.

      Note: If the cylinder liner is turned in the cylinder block, there will be a difference in the liner projection.

5. If the liner projection is not 0.129 ± 0.070 mm (0.0051 ± 0.0028 inch), check the thickness of the following items:

   (5) Spacer plate ... 12.313 ± 0.025 mm (0.4848 ± 0.0010 inch)

   (6) Spacer plate gasket ... 0.208 ± 0.025 mm (0.0082 ± 0.0010 inch)

   (7) Cylinder liner flange ... 12.65 ± 0.02 mm (0.498 ± 0.001 inch)

6. Place an alignment mark on the cylinder liner and the cylinder block in order to install the cylinder liner in the same position.

7. Remove Tooling (A), Tooling (B), and the spacer plate. Also remove the cylinder liner.

8. Apply liquid soap to seals (5), the grooves of the cylinder liner, and the cylinder block.

9. Install seals (5) on the cylinder liner.

10. Dip the filler band (6) in clean engine oil. Immediately install filler band (6) in the groove that is under the cylinder liner flange.

11. Install the cylinder liner immediately after filler band (6) is installed on the cylinder liner. Ensure that the marks that are on the cylinder liner and the cylinder block are aligned.

12. Use Tooling (C) to press the cylinder liner into the cylinder block.
