B 2P-8260 Cylinder Liner Installation Tool 1
Note: The following procedure alleviates the need for the crossbar to hold the cylinder liners
during cylinder liner projection measurements.
1. Clean the cylinder liner flange and the cylinder block surface. Remove any nicks on the top
of the cylinder block.
2. Install clean cylinder liners without the rubber seals or the filler band. Install a new spacer
plate gasket and the clean spacer plate.

4. Loosen bolt (5) until dial indicator (6) can be moved. Place gauge body (7) and dial
indicator (6) on the long side of gauge (8) .
5. Slide dial indicator (6) into position until the point contacts gauge (8). Slide dial indicator
(6) until the needle of the dial indicator makes a quarter of a revolution clockwise. The
needle should be in a vertical position. Tighten bolt (5) and zero dial indicator (6) .
6. Place gauge body (7) on the spacer plate with the dial indicator point on the cylinder liner
flange. Read the dial indicator in order to find the amount of liner projection. Check the
liner projection at four locations (every 90 degrees) around each cylinder liner.
Table 3
Specifications
Liner Projection 0.033 mm (.0013 inch) to
0.175 mm (.0069 inch)
Maximum Variation in Each Cylinder
0.051 mm (.0020 inch)
Maximum Average Variation Between Adjacent Cylinders
0.051 mm (.0020 inch)
Maximum Variation Between All Cylinders
0.102 mm (.0040 inch)
7. If the cylinder liner projection is out of specification, rotate the cylinder liner in the bore and
repeat the procedure. If the cylinder liner projection measurements are again out of
specification, try installing the cylinder liner in a different cylinder bore to improve the
measurements.
Note: Do not exceed the maximum liner projection of 0.175 mm (0.0069 inch). Cracking in
the flange of the cylinder liner results from excessive cylinder liner projection
measurements.
8. If the maximum variation between cylinder liners is greater than the recommended
specification, shims must be used in order to reach the correct specification.
9. When the cylinder liner projection for each cylinder liner is within the recommended
specification, mark each cylinder liner for the proper location in the bore and remove the
cylinder liners.
10. Lubricate the O-ring seals, the cylinder liner, and the upper filler band before installation.
Note: If the lower O-ring seals are black in color, apply liquid soap on the lower O-ring
seals and the cylinder block. Use clean engine oil on the upper filler band.
Note: If the lower O-rings are brown in color, apply engine oil on the lower O-ring seals,
the cylinder block, and the upper filler band.

Apply 5P-3975 Rubber Lubricant and/or clean engine oil immediately
before assembly. If the 5P-3975 Rubber Lubricant or engine oil is
applied too early, the filler bands and/or O-ring seals may swell and
the filler bands and/or O-ring seals may be pinched under the cylinder
liner during installation.
11. Apply liquid soap on the bottom cylinder liner bore in the cylinder block. Apply liquid soap
on the grooves of the cylinder liner and on O-ring seals (4). Install O-ring seals (4) on the
cylinder liner.
12. Lubricate filler band (5) with clean engine oil and install filler band (5) on cylinder liner (6).
Install cylinder liner (6) into the engine block immediately after you lubricate the cylinder
liner. This helps to prevent swelling of the filler band.
13. Ensure that the mark on the cylinder liner is in alignment with the mark on the cylinder
block. Use Tool (B) to press each of the cylinder liners into position.
