Install Tooling (A) around the cylinder liner bore. Tighten the six bolts from Tooling (A) evenly in four steps to a torque of 95 N m (70 lb ft).
Use Tooling (B) to measure the cylinder liner projection at locations A, B, C, and D. Note: Measure the cylinder liner projection around the cylinder liner. Dimensions for the cylinder liner projections must be within specifications. If the dimensions are not in tolerance, rotate the cylinder liner to a new position in the cylinder bore. It may be necessary to move the cylinder liner to a different cylinder bore. Check the cylinder liner projection again.
Dimensions for the cylinder liner projection must be within specifications. The machined counterbore surface to the top surface of the cylinder block can be changed. Note: Refer to Special Instruction, FM055228, "Using Caterpillar Cylinder Pack Pulling Tools" for additional information in the use of Tooling (D). Refer to Testing and Adjusting, "Cylinder Liner Projection - Inspect" in order to find the thickness of the shims, the part number and the installation procedure for the cylinder liner.
Put a mark on cylinder liner (1) and the spacer plate so the cylinder liner can be installed in the same position. Remove Tooling (A) and Tooling (B). Remove cylinder liner (1).
Illustration 4 g00575805Note: Apply Tooling (E) and clean engine oil immediately before assembly. If Tooling (E) or engine oil is applied too early, the filler bands and O-ring seals may swell and the filler bands and O-ring seals may be pinched under the cylinder liner during installation.
Apply Tooling (E) on the three lower seals (3) and the cylinder bore. Install the three bottom seals on the cylinder liner.
Immerse upper filler band (2) in clean engine oil. Install the filler band on the cylinder liner.
Install the cylinder immediately into the cylinder block.
