5 Claims, 4 Drawing Figures BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a new and improved method for removing sleeves and cylinder liners from internal combustion engines, and particularly from General Motors diesel engines. The device may be quickly and easily inserted inside the cylinder in contact with the sleeve to be removed and the sleeve may then easily be forced to the top of the cylinder by the action of the piston serving that cylinder as the engine is turned over. While the device is particularly well adapted to General Motors diesel engines because of the use of perforated liners in the cylinders of these engines, it will be recognized that the sleeve removing device of this invention may be adapted to substantially any type of engine having similar perforated liners.
2. Description of the Prior Art I-Ieretofore, various apparatus and methods have been utilized to remove cylinder liners from engines of the internal combustion design and particularly, diesel engines.
Among the t conventional techniques for removing cylinder liners from internal combustion engines and particularly from diesel engines, is the use of a puller clamp device which is equipped with a lower and upper clamp, both of which must be positioned in precisely the right spot inside the liner, cocked in the proper mannerand then struck with a puller weight to release the liner from the cylinder block. Although the cylinder liners are a slip fit in the engine block, considerable effort is many times required to loosen the liner, particularly if the engine has been in service for a considerable length of time, and the puller clamps must be positioned and cocked properly in order for the liner to be loosened properly. Such a technique requires considerable time and effort and not infrequently results in the cracking or scoring of cylinder liners, thereby rendering them unfit for future use. Since the liners must be clear of burrs in order to prevent premature failure of the piston and the rings, and must also be free of fretting," which may be caused by slight movements of the liner in the block, the conventional method of removing the cylinder by use of puller clamps frequently results in the need for additional work on the liners to prepare them for further use in the engine.
A less desirable but frequently used technique for loosening cylinder liners in the engine is bytapping the liners with a chisel or a rod in order to break them loose from the cylinder wall. It is readily apparent that such a procedure frequently results in cracked or scored cylinder liners and also fosters the problems of creation of burrs and fretting, previously noted above.
Accordingly, an object of this invention is to provide an improved method for removing sleeves and liners from the cylinders of internal combustion engines and particularly engines built by General Motors Corporation.
Another object of the invention is to provide a new and improved sleeve removing device which is simple in design, easy to use, and which results in minimum damage to the cylinder liner in the removal process.
A still further object of the invention is to provide a sleeve removing device for use in internal combustion engines which is more economical to use than conventional techniques and saves both labor and materials in the removal of cylinder liners from the engines.
Yet another object of the invention is to provide a sleeve removing device which will not create burrs" in the cylinder liner and which will not crack, score," or fret the liner.
A still further object of the invention is to provide a sleeve removing device for diesel engines which may be inserted in the cylinder of the engine and subsequently uses the operation of the engine itself to remove the cylinder liner.
SUMMARY OF THE INVENTION These and other objects of the invention are provided in a sleeve removing device which includes the following elements:
1. A hollow receiving cylinder having a receiving cylinder cap at one end and a spring positioned in the hollow interior.
2. A plunger having a plunger cap at one end thereof adapted to fit concentrically inside the receiving cylinder.
3. A rod traversing the interior of the plunger and receiving cylinder and projecting outwardly of the receiving cylinder cap and the plunger cap to engage the apertures in a cylinder liner.
BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood in view of the following description presented with reference to the accompanying drawings.
FIG. 1 of the drawings is a perspective exploded view of the sleeve removing device of this invention;
FIG. 2 is a side-sectional view of the sleeve removing device of this invention illustrating the interrelationship of the parts of the device.
FIG. 3 is an elevational view of a typical cylinder sleeve or liner used in many internal combustion engines and particularly in diesel engines.
FIG. 4 is a top view of the open cylinder in a conventional internal combustion General Motors built diesel engine showing the cylinder wall], cylinder liner or sleeve, and the sleeve removing device positioned inside the cylinder in contact with the sleeve and ready for removal of the sleeve.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIG. 1 of the drawings, the sleeve removing device illustrated by reference numeral 1 is shown in exploded form illustrating receiving cylinder 2 equipped with receiving cylinder cap 3 and receiving cylinder lip 4. Receiving cylinder lip aperture 5 is adapted to receive spring 14 and plunger 9 which operates against the bias of spring 14.S leeve engaging rod 13 is adapted to traverse the length of plunger 9 and receiving cylinder 2 and project from the ends of plunger cap 10 and receiving cylinder cap 3. A hole 6 in receiving cylinder 2 is adapted to receive pin 7 which also traverses slot 11 in plunger 9 in order to limit the travel of plunger 9 against the bias of spring 14. Receiving cylinder cap aperture 8 is further adapted to receive a pin 7, in order to restrict movement of sleeve engaging rod 13 with respect to receiving cylinder 2 and receiving cylinder cap 3. Receiving cylinder cap 3, receiving cylinder lip 4 and plunger cap 10 may be flattened on the top and bottom as illustrated to provide a firm base for engagement of the engine piston, the procedure of which will be more particularly described hereinafter.
FIG. 2 illustrates a sectional view of the sleeve removing device showing the bias of plunger 9 against spring 14 inside receiving cylinder 2. Thus, plunger 9 and plunger cap 10 are allowed to move with respect to receiving cylinder 2 and sleeve engaging rod 13 throughout the length of slot 11 against the bias of spring 14, in order to position the device within the cylinder of an engine and in contact with the cylinder sleeve. Slot 11 can be lengthened or shortened as necessary in receiving cylinder 2 in order to provide variable travel of plunger 9 with respect to the receiving cylinder. The projecting ends of sleeve engaging rod 13 are adapted to engage perforations or apertures in the cylinder liner illustrated in FlG. 3, to stabilize the device during the removal operation.
FIG. 3 illustrates a typical sleeve or liner which is removed by the sleeve removing device of this invention. The projections of sleeve engaging rod 13 illustrated in FIGS. 1 and 2 of the drawing are adapted to engage cylinder sleeve opening 17 and force the liner upwardly and out of the cylinder when the engine piston is brought upward into contact with sleeve removing device l by turning over the engine.
FIG. 4 illustrates sleeve removing device I inserted inside the cylinder wall and cylinder liner, with the projections of sleeve engaging rod 13 in place inside cylinder sleeve openings 17. The bias of spring 14 causes plunger cap 10 and receiving cylinder cap 3 to fit snugly inside cylinder sleeve 16 and when the piston moves upwardly to engage the device, both the device and the sleeve are forced upwardly and to the top of cylinder 15.
The device is inserted inside the engine cylinder as illustrated in FIG. 4, by forcing plunger 9 against spring 14 and inserting the end of sleeve engaging rod 13 projecting from plunger cap 10 through a cylinder sleeve opening 17 and into the porthole opening in the engine block adjacent the cylinder sleeve opening. The opposite end of sleeve engaging rod 13 is then inserted in an opposing cylinder sleeve opening 17, and plunger 9 is allowed to retract by the action of spring 14 to permit the extreme ends of receiving cylinder cap 3 and plunger cap 10 to grip cylinder sleeve 16. This retracting action also causes the end of sleeve engaging rod 13 projecting from plunger cap 10 to withdraw from the porthole opening in the engine block to a position inside the cylinder sleeve opening 17, and cylinder sleeve 16 is ready for removal by contact between the sleeve removing device and the engine piston.
While the disclosure of this invention is directed primarily to the removal of cylinder liners built into engines constructed by General Motors Corporation, it will be appreciated that the invention may be adapted to any engine having apertures large enough to receive sleeve engaging rod 13 in the liners themselves.
