Transmission tools

Claim 3

The method of claim 1 wherein said stem and plate are rigidly connected with said stem extending from said plate at substantially right angles, said forcing step including inserting said stem into said housing hole and pressing on said plate to cause said abutment to forcibly engage said spring retainer.

Claim 4

The method of claim 1 wherein said plug is in threaded relation to said plate, and said forcing step constitutes turning the threads in a direction to advance said plug inwardly of said housing bore to forcibly engage said spring retainer.

Claim 5

An improved tool for use in compressing the kickdown spring of a servo in an automatic transmission so that a spring retainer may be displaced from abutment with a snap ring lock whereby the latter may be removed, said transmission having a housing with a bore in which said servo is disposed, and a hole adjacent to said servo, said improved tool comprising: a rigid stem of a transverse size to freely fit into said hole and when canted to bind in said hole and thereby hold said tool in position on said housing, said stem having a roughened peripheral surface so that it has good gripping engagement with the surface defining said housing hole when said stem is canted, a rigid plate connected at one end to said stem and being of a length so that its other end overlies said servo, and means interposed between said plate and said spring retainer to apply pressure thereagainst and move it inwardly of said housing bore and displace it from abutment with said snap ring lock so that the latter is accessible for removal from said housing bore.

Claim 6

An improved tool for use in compressing the kickdown spring of a servo in an automatic transmission so that a spring retainer may be displaced from abutment with a snap ring lock whereby the latter may be removed, said transmission having a housing with a bore in which said servo is disposed, and a hole adjacent to said servo, said improved tool comprising: a rigid stem of a transverse size to freely fit into said hole and when canted to bind in said hole and thereby hold said tool in position on said housing, said stem having a roughened peripheral surface so that it has good gripping engagement with the surface defining said housing hole when said stem is canted, a rigid plate connected at one end to said stem and being of a length so that its other end overlies said servo, and means interposed between said plate and said spring retainer to apply pressure thereagainst and move it inwardly of said housing bore and displace it from abutment with said snap ring lock so that the latter is accessible for removal from said housing bore.

Claim 7

The construction according to claim 1 wherein said interposed means includes a screw rod threaded through said plate other end and it and said stem extend from said plate substantially at right angles thereto, and a plug connected to that end of said screw rod which is on the same side of said plate as said stem, said plug being forced against said spring retainer by rotation of said screw rod in a predetermined direction.

Claim 8

The construction according to claim 4 wherein said spring retainer has a central aperture, and said interposed means comprises a plug having a pilot portion to fit into said aperture and a rounded head portion bearing against the adjacent facing surface of said plate.
