42.1 DESCRIPTION AND OPERATION OF CYLINDER BLOCK AND RELATED PARTS

The cylinder liners are designed as "bottom stop" cylinder liners which means that the cylinder

liners are installed with a lower collar in the cylinder block. This design allows for a shorter

distance between cylinders and a more compact design for the cylinder block. Each cylinder liner

has two sealing rings: t he upper s ealing ring seals the upper coolant j acket to the cylinder block

bore; the lower sealing ring seals the lower coolant jacket to the cylinder block bore.

Figure 42-2 Cylinder Block, Cylinder Liners and Related Parts

The cylinder block has 1.5 mm counterbores machined on top for the cylinder head to cylinder

block sealing surface. The lubrication and coolant holes in the cylinder b lock supply the cylinder

head with oil a nd coolant. This allows for a superior sealing pressure between the gasket,

cylinder head and cylinder block.

The cylinder block uses replaceable, wet-type cylinder liners.
