WET CYLINDER LINER:

The location bores and particularly the running surfaces in the cylinder block must be cleaned carefully and they must

be undamaged. Corroded surfaces must be reworked (used flange liners and outer diameter oversize liners). As this is

done, make sure that the liners moves in easily and that they take up the correct position (the projecting length of the

liner must be in accordance with the regulations of the engine manufacture). After the liner has been installed with the

seat rings that belong to it.

(use slip agent), the cylinder diameter is to be checked particularly in the region of seal rings so as to determine whether

any deformation has been caused by pinched sealing rings. Using the wrong sealing rings (wrong diameter/ wrong

materials) can a narrowing of the cylinder which can lead to engine damage.The cooling system should be pressure

tested after the liners have been installed so as to determine whether there is any leakage before the engine is started.

SEMI-FINISH CYLINDER LINER:

The surface which supports the flange must be vertical to the location bore and it must be sufficiently and evenly beveled. If the

liner flange is unevenly supported it can tear off. After the installation of the liner, which is only semi-finished in its inside

diameter, this cylinder boring is finely bored and then finished by honing until it has the specified dimensions or, in the case of

finely bored liner.It is only finished by honing (tolerance accordingly to DIN ISO H5). The surface of the liner must be flush to the

sealing surface of the cylinder block, if necessary,the block surface and the liner must be finished by surface grinding.

FINISH CYLINDER LINER:

Before the liner is installed, the location bore in the cylinder block must be cleaned carefully and must be checked to

ensure the accuracy of the dimensions and to determine whether any distortion has occurred. Out of center or damaged

bores can be reworked for the installation of oversize liners. It is important for this that the locating bore is cylindrical, as

this is what determines the geometrical shape of the inside of the pressed in, thin walled liner.

AIR COOLING CYLINDER LINER:

5)In accordance with the instructions from the engine manufacture, cast iron cylinders or light alloy cylinders are used.

Light alloy cylinders are separated into several groups due to the small installation clearance in the standard cylinder dimensions.
