For checking the cylinder liner projection with the liner out of the cylinder block, ensure that the following surfaces are clean prior to measuring:
Cylinder liner flanges
Spacer plate
Spacer plate gasketFor checking the installed cylinder liner projection, ensure that the following surfaces are clean prior to measuring:
Top surface of the cylinder block
Cylinder liner bores
Cylinder liner flanges
Spacer plates

Illustration 2 g02247495
Use micrometer (T5) to measure the thickness of the following items:
(X) Spacer Plate
(Y) Spacer Plate Gasket
(Z) Cylinder Liner FlangeNote: To determine the cylinder liner projection, subtract the thickness of the spacer plate and gasket from the thickness of the cylinder liner flange.
Refer to Table 1 for the correct value of your cylinder liner projection.Cylinder Liner Installed in the Cylinder Block - Check

(1) Spacer plate
Install a new gasket and spacer plate (1) on the cylinder block.
Install the cylinder liner in the cylinder block without seals or bands.
Hold spacer plate (1) and the cylinder liner in position according to the following procedure:
Install four bolts (T1) and four washers (T3) around spacer plate (1). Tighten the bolts evenly to a torque of 95 N m (70 lb ft).
Install the following components: crossblock (T2), two pusher-puller plates (T4), and two bolts (T6). Ensure that crossblock (T2) is in position at the center of the cylinder liner. Ensure that the surface of the cylinder liner is clean. Tighten the bolts evenly to a torque of 70 N m (50 lb ft).
Check the distance from the bottom edge of crossblock (T2) to the top edge of spacer plate (1). The vertical distance from both ends of the crossblock (T2) must be equal.
