Subaru gudgeon pin tool

The upstanding post 16 is itself provided with a reaction member 17 with an undercut surface 18, the undercut surface 18 being a reaction surface which is engaged by a shelf 19 at the tail end of each of the half arms 12 and There is also a threaded aperture 20 in one side of the post 16, to receive a threaded clamping screw not shown. The post 16 has a flat land 22 at its upper end, and is flanked by two upwardly projecting portions The projecting portions 23 present locating faces 24 which locate against the side surfaces 25 of the half arms 12 and 13, and the clamping screw clamps the half arms together so that when clamped together they present an arm assembly 26 FIG.

The web 27 in each of the half arms 12 and 13 is provided with a semi-circular recess 31, and the semi-circular recesses 31 combine upon assembly of the half arms face to face to provide an ejection aperture for a gudgeon pin 32 of a piston In use, the two half arms are readily entered into the spaces on respective sides of the connecting rod 28, and can be positioned beneath the reciprocating end thereof, to lie face to face and give support for the entire area of the connecting rod which surrounds the gudgeon pin A consideration of the above embodiment will therefore indicate that the invention, although providing a more complex tool than heretofore, provides a tool which nevertheless avoids possibility of danger to the piston shape, and provides the maximum support for the reciprocating end of the connecting rod which can be achieved with a tool of this type.

United States Patent A tool 10 for removal of a gudgeon pin 33 from an assembly 34 of a reciprocating end of a connecting rod 28 and a piston wherein there is provided a base 11 , a post 16 , a pair of projecting half-arms 12, 13 projecting forwardly of the post 16 and above the base 11 , each of the half-arms 12, 13 each having a support web 27 with a semi-circular inner edge which co-operates with the inner edge of the other half-arm 13, 12 to provide an ejection aperture 32 for the gudgeon pin 33 while the webs 27 of the half-arms 13, 12 resist the ejection pressure and thereby avoid piston damage.

Wait until the ticking starts then turn off the engine and check for play in the lash adjusters. If its not making noise they will be pumped up and there will be no "squish".

You could also swap to solid lash adjusters by swapping in whole rocker assemblies from a 2. Thanks for the quick responses guys. I dropped the oil and it looked good. And then I found the cam sprocket on that side lacking torque. Back to just good ol' piston slap for me. At the moment, it's in a 95 Impreza for test purposes.

It is known that fork-like spacers have been proposed heretofore, but there are instances wherein they are not sufficiently rigid, and do not engage a sufficient area surrounding the gudgeon pin to ensure that no deformation will occur. It is therefore the object of this invention to provide an improvement, wherein the gudgeon pin surround is more nearly complete than with previously proposed arrangements, and in an embodiment of the invention there is provided a base, a pair of projecting half arms, an engagement means between the half arms and the base to retain the half arms in position, each of the half arms having a web with a semi-circular aperture which matches the semi-circular aperture of the other half arm to provide an ejection aperture for the gudgeon pin.

An embodiment of the invention is described hereunder in some further detail with reference to and is illustrated in the accompanying drawings in which. Referring to the drawings, a removal tool 10 comprises three components, there being a base 11, a left hand half arm 12 and a right hand half arm The base 11 is provided with a horizontal flat plate 15 and an upstanding post The upstanding post 16 is itself provided with a reaction member 17 with an undercut surface 18, the undercut surface 18 being a reaction surface which is engaged by a shelf 19 at the tail end of each of the half arms 12 and There is also a threaded aperture 20 in one side of the post 16, to receive a threaded clamping screw not shown.

The post 16 has a flat land 22 at its upper end, and is flanked by two upwardly projecting portions The projecting portions 23 present locating faces 24 which locate against the side surfaces 25 of the half arms 12 and 13, and the clamping screw clamps the half arms together so that when clamped together they present an arm assembly 26 FIG. The web 27 in each of the half arms 12 and 13 is provided with a semi-circular recess 31, and the semi-circular recesses 31 combine upon assembly of the half arms face to face to provide an ejection aperture for a gudgeon pin 32 of a piston In use, the two half arms are readily entered into the spaces on respective sides of the connecting rod 28, and can be positioned beneath the reciprocating end thereof, to lie face to face and give support for the entire area of the connecting rod which surrounds the gudgeon pin In the same way as the tool is used for removal of the gudgeon pin, it can be used for assembly.

A consideration of the above embodiment will therefore indicate that the invention, although providing a more complex tool than heretofore, provides a tool which nevertheless avoids possibility of danger to the piston shape, and provides the maximum support for the reciprocating end of the connecting rod which can be achieved with a tool of this type.
