Abstract
A tool for disassembling and assembling bearings which support an engine mounting frame of an internal combustion engine, is mounted on a base, a bearing having opposing metal securing plates and a resiliently deformable damping element extending between the securing plates, said tool comprising opposing, parallel mounting plates, each mounting plate being mountable on a securing plate of a bearing to be dissassembled or assembled, and comprising a turnbuckle, via which the opposing mounting plates are operatively connected.
Claims10
A tool configured to remove and install a bearing comprising metallicsecuring plates located opposite one another and a rubber-elastically deformable damping element extending between the securing plates, via which an engine mounting frame of an internal combustion engine is mounted on a base, comprising:
- parallel mounting plates located opposite one another each comprises at least one passage opening for mounting bolts, wherein each respective parallel mounting plate has a first side that faces a respective first side of the other parallel mounting plate and is configured to be mounted by a respective second side opposite the first side to a respective securing plate of a bearing to be removed or installed, wherein the passage openings for mounting bolts are configured to mate with threaded holes in the respective securing plates via which the parallel mounting plates are mountable to the respective securing plates of the bearing to be removed or installed such that the second side of each parallel mounting plate is in direct contact with a respective securing plate;
- and a turnbuckle arranged between the first sides of the parallel mounting plates, via which the parallel mounting plates located opposite one another are operatively connected, wherein a longitudinal axis of the turnbuckle is parallel to a longitudinal axis of the rubber-elastically deformable damping element.
A method for changing a bearing, via which an engine mounting frame of an internal combustion engine is mounted on a base, wherein the bearing comprises metallic securing plates located opposite one another and a rubber-elastically deformable damping element extending between the securing plates, having a tool comprising parallel mounting plates located opposite one another, wherein each respective parallel mounting plate is configured to be mounted to a respective securing plate of a bearing to be removed or installed;
- and a turnbuckle, via which the parallel mounting plates located opposite one another are operatively connected, comprising:
- actuating the turnbuckle of the tool to move the parallel mounting plates of the tool towards one another, so that a distance between outer surfaces of the parallel mounting plates of the tool facing away from one another is smaller than a distance between inner surfaces of the securing plates of the bearing to be removed facing one another, which acts on the engine mounting frame and base;
- arranging the tool between the securing plates located opposite one another so that the outer surfaces of the parallel mounting plates face the inner surfaces of the securing plates;
- actuating the turnbuckle of the tool to move the parallel mounting plates of the tool away from one another so that the outer surfaces of the parallel mounting plates come to lie against the inner surfaces of the securing plates of the bearing to be removed;
- mounting the parallel mounting plates of the tool to the securing plates of the bearing and disconnecting the securing plates of the bearing to be removed from engine mounting frame and base;
- actuating the turnbuckle of the tool to move the parallel mounting plates of the tool and the securing plates of the bearing to be removed toward one another while tensioning the rubber-elastically deformable damping element of the bearing to be removed;
- and
- removing the bearing to be removed and inserting a bearing to be installed.
