After the cylinder liner is prepared, use Tooling (B) to press the cylinder liner into the cylinder block.
Use a 0.02 mm (0.001 inch) feeler gauge to verify that the cylinder liner is against the cylinder block. Check for gaps in multiple places. A gap between the cylinder liner and the cylinder block can indicate a liner seal that is pinched. A liner seal that is pinched will compromise the life of the liner seal and the cylinder head gasket.Types of Cylinder Liner Seals
There are two types of seals that can be used on the cylinder liners.Type 1

Apply liquid soap on the grooves for O-ring seals (1) and on O-ring seals (1). Install O-ring seals (1) on cylinder liner (2). Also, coat the bottom cylinder block bore, Location (N), with liquid soap.
Dip filler band (3) in clean engine oil. Immediately install filler band (3) onto cylinder liner (2).
Immediately install cylinder liner (2) before filler band (3) can expand.Type 2

Liner seal (4) requires a machined chamfer at the top edge of the liner bore to install the liner seal.
A chamfer can be machined into the top edge of the bore in the block for the cylinder liner. Refer to Special Instruction, SEBF9203 for the correct procedure for machining the chamfer.Note: Liner seat inserts that include the chamfer are also available. Refer to Reuse and Salvage Guidelines, SEBF8255.
Use Tooling (D) on the inside surface of the top bore, Location (M).
Ensure that the liner groove for liner seal (4) is clean and dry. Install liner seal (4) on cylinder liner (2). Apply a thin coat of Tooling (C) to the cylinder block on the machined chamfer to a distance of 5 mm (0.2 inch) below the machined chamfer. Apply Tooling (C) to liner seal (4).Note: Do not apply Tooling (C) to the liner flange or the top of the cylinder block.
Apply liquid soap on the grooves for O-ring seals (1) and on O-ring seals (1). Install O-ring seals (1) on cylinder liner (2). Also, coat the bottom cylinder block bore, Location (N), with liquid soap.End By:
