NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, PERJ1017, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat^® products. Dispose of all fluids according to local regulations and mandates.

Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.

Place covers over the crankshaft journals to shield the journals from dirt and coolant.

Installation Procedure

NOTICE

Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.

Measure liner projection. Refer to Testing and Adjusting, "Cylinder liner projection".
Prepare cylinder liner (1) for installation. There are two types of seals that can be used on the cylinder liners.
1. Apply liquid soap on the grooves for O-ring seals (2) and on O-ring seals (2). Install O-ring seals (2) on cylinder liner (1). Also, coat the bottom cylinder block bore, Location (N), with liquid soap.
2. Dip filler band (3) in clean engine oil. Immediately install filler band (3) onto cylinder liner (1).
3. Immediately install cylinder liner (1) before filler band (3) can expand.

4. Liner seal (4) requires a machined chamfer at the top edge of the liner bore to install the liner seal.
5. A chamfer can be machined into the top edge of the bore in the block for the cylinder liner. Refer to Reuse and Salvage Guidelines, SEBF8255, "Reuse and Salvage for 3500 Engine Cylinder Blocks", Procedure to Chamfer Liner Bores 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, "Reuse and Salvage for 3500 Engine Cylinder Blocks".
6. Ensure that the liner groove for liner seal (4) is clean and dry. Install liner seal (4) on cylinder liner (1). 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.
7. Apply liquid soap on the grooves for O-ring seals (2) and on O-ring seals (2). Install O-ring seals (2) on cylinder liner (1). Also, coat the bottom cylinder block bore, Location (N), with liquid soap.

Use Tooling (B) to press cylinder liner (1) into the cylinder block.
Use a 0.02 mm (0.001 inch) feeler gauge to verify that cylinder liner (1) is against the cylinder block. Check for gaps in multiple places.
Note: 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.
Measure liner projection again to ensure that cylinder liner projection is still within specification. Refer to Testing and Adjusting, "Cylinder liner projection". A cylinder liner projection that is no longer within specification 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.
Repeat Step 1 through Step 5 for the remaining cylinder liners.
