After cylinder sleeve (5) is installed in the cylinder bore, it is acceptable for the top of the cylinder sleeve to extend a maximum of 0.013 mm (0.00051 inch), above the cylinder block top deck. For best installation results, the cylinder sleeve should be flush with the top deck of the cylinder block.Note: It is acceptable to machine the top of the cylinder sleeve, so it is even with the cylinder block top deck.
If the top of the cylinder sleeve is machined, do NOT nick or cause damage to the top deck of the cylinder block. To ensure a correct seal between the bottom of the cylinder head and the top surface of the cylinder block near the cylinder sleeve, the cylinder head gasket MUST have a smooth surface to seal against.

For 3114, 3116, and 3126 Engines, after the sleeve is inserted into the bore, machine a chamfer as show in Illustration 47.
Use the 1P-3565 Chamfering Group to remove the sharp corner at the bottom of each cylinder bore. The chamfer must be approximately 2.3 mm (0.09055 inch) x 15 degrees. The chamfer is necessary to prevent scuffing of the piston skirt.Line Boring the Cylinder Block
Tooling
Use 1P-4000 Line Boring Tool Group to perform the line bore. Refer to Special Instruction, SMHS7606, "Using 1P-4000 Line Boring Tool Group" for a description of this tool.Centering Rings
Standard centering rings and oversized centering rings must be purchased.Changes to Boring Procedure
Refer to Special Instruction, SMHS7606, "Use of 1P-4000 Line Boring Tool Group".Place the 4C-9765 Centering Rings with the oiler on each side of the cap that is being replaced. For an end cap, place 4C-9765 Centering Rings in the second and fourth main bearing bores on four cylinder engines and in the second and fifth bearing bores on six cylinder engines.

All other bearing cap bolts should be tightened to the specifications in the service manual.Place the tool bit in the holder and set the micrometer 1.78 mm (0.070 inch) less than the finished bore diameter. The finished bore diameter is 95.000 0.013 mm (3.7402 0.0005 inch). Verify that this dimension before bearing caps are removed.
