Abstract
Removal of cylinder liners from engine blocks is a critical overhaul operation. Conventional mechanical pullers or impact methods can damage the liner seat or block. A hydraulic liner puller provides controllable force and reduces the risk of damage.
This project develops a Hydraulic Cylinder Liner Puller in which a hydraulic cylinder (or jack) generates the extraction force. A rigid fabricated frame, adjustable arms and adapter plates engage the liner so that the hydraulic force pulls it axially out of the bore. Key design aspects include force requirement estimation, structural strength of the frame and arms, hydraulic pressure selection, and safe operation procedures. The unit demonstrates practical application of hydraulics and machine design suitable for academic evaluation.
It is an excellent final-year project for Mechanical, Automobile, Production and Manufacturing Engineering students, combining fabrication, hydraulic systems and workshop tooling concepts.
