ABSTRACT:
To service an engine, it is frequently determined that a cylinder liner and piston must be replaced. Removal is difficult and time consuming if the piston is first removed through the liner and the liner is then grasped from below and pulled from the block. A method includes inserting a tool into a bore of the liner and expanding the tool into a frictional fit against the liner. A force is applied on the tool to forcibly move the liner. The piston and associated rings and rod are held in place in the liner by a partial vacuum for removal with the liner as a complete unit.
