Calculating Cylinder Liner Projection
The following method for calculating the liner projection is the preferred method under these circumstances:
Single cylinder head joint repair
Engine rebuildNote: When installation of spare used spacer plates and cylinder liners is desired, having the stocked parts measured and matched will reduce repair time.Note: The method of measuring liner projection that uses the 8T-0455 Liner Projection Tool Group can still be used.Regardless of the procedure, the contact surface of the cylinder block for the liner flange and spacer plate must be thoroughly clean before installation of replacement parts.If a new spacer plate and cylinder liner will be installed in the same cylinder, there is no need to calculate the cylinder liner projection. The production process control for the parts is adequate.If a used spacer plate or cylinder liner will be installed, perform the following measurement and calculation procedure.

Required Tools    
A     8T-0455 Liner Projection Tool Group    
B     Digital micrometer with a resolution of 0.001 mm    The cylinder liner projection is now a calculation based on measurement of parts that uses the following dimensions:
The average thickness of the flange for the 211-7826 Cylinder Block Liner, measured in four places
The average thickness of the 110-6994 Spacer Plate, measured in four places
The nominal manufactured thickness of a new 144-5692 Plate Gasket A new 144-5692 Plate Gasket must be installed with the spacer plate and cylinder liner.Use the following procedure to calculate the cylinder liner projection.
Illustration 3 g02657236
(X) Average thickness of the spacer plate (Y) Nominal thickness of the spacer plate gasket (Z) Average thickness of the cylinder liner flange
Use tool (B) to measure the thickness of the cylinder liner flange at four equally spaced locations around the circumference of the flange. Determine the average of the measurements.The result is dimension (Z). Mark the result on the cylinder liner with a permanent marker. Do not scribe the material.
Illustration 4 g02657156
Use tool (B) to measure the thickness of the spacer plate at the four locations identified by "X" in Illustration 4. Determine the average of the measurements.The result is measurement (X). Mark the result on the spacer plate with a permanent marker. Do not scribe the material.
Compare the average measurements to the dimensions listed in Table 2.If the average measured dimensions are within the acceptable range, the parts can be installed.If the average measured dimensions are not within the acceptable range, the parts cannot be installed. New parts must be obtained.Note: There is no need to measure the thickness of the 144-5692 Plate Gasket because a new gasket is always installed. The nominal manufacturing dimension is used in the calculation.Note: Reference Test and Adjusting, UENR0519, "Cylinder Liner Projection"
