A cylinder sleeve puller for use in combination with a cylinder positioned in an engine block and having a removable sleeve liner therein comprising a rigid support frame having a horizontal member supported by a pair of depending vertical ends, said vertical ends being adapted to be disposed on each side of the cylinder to be worked upon in engagement with the surface of the engine block adjacent such cylinder; a threaded rod extending through the center of said horizontal member and adapted to be threaded up and down therethrough within said cylinder and its associated removable sleeve liner; a horizontally extendible lifting member pivotally connected to the base of said threaded rod and adapted to pivot to a downward angle to permit insertion into said cylinder; and sleeve-engaging lift surfaces at each end of said lifting member to engage with the base of said sleeve and to exert upward extracting forces thereon when said lifting plate is pulled upward by action of the attached threaded rod. This construction allows automatic centering of the lifting force. Modifications include an oiler for providing lubricating oil to the threaded rod and its associated bearings.
