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.

Abstract: To service an engine (10), it is frequently determined that a cylinder liner (12) and piston (18) must be replaced. It is difficult and time consuming to first install the liner (12) and then the piston (18) with the rings (20) and connecting rod (22). A pre-assembled unit (36) including the liner (12) and piston (18) may be installed on the engine according to a disclosed method. The unitary assembly simplifies steps at the service facility and, if desired, permits assembly of the unit (36) prior to shipment to the service facility to reduce shipping space and cost.
