Cummins ISX11.9 CM2250 – Service Manual 001-028   Cylinder Liner

CAUTION  The liners must be installed within 30 seconds after being lubricated with oil. If the liners are not installed within this time limit, the o-rings will swell and be damaged when the liner is installed.

Make sure the cylinder block and all parts are clean before assembly.

Use clean vegetable oil to coat the liner o-ring seals.

Install the o-ring seal on the liner. Make sure the o-ring seal does not roll during installation.

Install the liner into the cylinder block.

When acceptable used liners are installed, rotate the liners 90 degrees from their original position in the engine. Original thrust and anti-thrust surfaces must face the front and back of the cylinder block.

Use cylinder liner driver, Part Number 3164246, or equivalent, to drive the liner into the cylinder block bore.

If the liner does not seat properly, remove the liner. Inspect the counterbore seat and liner for nicks, burrs, and dirt.

Install the liner again.

The cylinder liner protrusion must be checked before installing the pistons and connecting rods.

Use a depth gauge, Part Number 3164438, to measure the liner protrusion at four points that are 90 degrees apart.
