Injector sleeve installation tool and removal tool kit

An injector sleeve kit including an injector sleeve removal tool and an injector sleeve installation tool comprising:

• said injector sleeve removal tool comprising:
• a tap with a nut welded to a non-threaded end thereof;
• a bolt with a loose nut threaded thereon and a flat washer slipped thereon;
• said bolt with said nut threaded thereon and said washer slipped thereon tightly threaded into said nut welded onto said non-threaded end of said tap;
• a hollow cylinder whose inner diameter is larger than the outer diameter of an injector sleeve to be removed and whose length is at least as long as said tap and welded nut combination but short enough to allow said tap section to penetrate and cut at least three threads into said injector sleeve;
• and
• a load bearing washer between said loose nut and said hollow cylinder;
• and said injector sleeve installation tool comprising:
• an outer approximately cylindrical shell having a circular aperture formed in a first end thereof, said circular aperture and a plurality of internal threads coaxial with said approximately cylindrical shell, internal threads adjacent to said circular aperture, a second end of said outer approximately cylindrical shell having at least three parallel longitudinal fingers being parallel to an axis of said outer approximately cylindrical shell, said three fingers separated by at least three longitudinal slits reaching from said second end to a distance of about half a length of said outer approximately cylindrical shell, said at least three fingers forming an outer circumference of said second end of said outer approximately cylindrical shell, said at least three fingers being tapered at said second end and having annular rib portions formed at selected positions along said outer approximately cylindrical shell, the entire length of said outer approximately cylindrical shell having a longitudinal cavity formed therein and
• a longitudinal expansion rod shaped to fill said cavity of said outer approximately cylindrical shell, said rod having a first tapered portion at a first end thereof and a second tapered portion placed at a position about one fourth of the way from said first end, said rod having a hexagonal shaped head at a second end thereof, said rod having external threads formed thereon adjacent to said hex head, said rod capable of being inserted and threaded into said outer approximately cylindrical shell, said threading of said rod into said outer approximately cylindrical shell causing said expansion rod to move axially inward to said outer approximately cylindrical shell, and an axial movement of said tapered sections of said rod causing radial spreading of said at least three fingers.

An injector sleeve installation tool, comprising:

• an expandable mandrel comprising a hollow cylindrical barrel defining a longitudinal cavity having an upper portion including a plurality of internal threads, and a lower expandable portion including a plurality of spaced apart vertical slits, said lower expandable portion terminating in a tapered distal end defining an end cap having a center aperture formed therein, and said expandable mandrel including at least one annular rib extending outwardly from said lower expandable portion a selected distance, and an upper end portion comprising means for cooperatively engaging a tool, said upper portion including an end portion for cooperatively engaging a tool;
• and
• a longitudinal expansion rod having a tapered end, said rod having a corresponding shape and size for cooperatively engaging said longitudinal cavity of said expandable mandrel, said rod including an upper portion and a lower portion having a smaller diameter than said upper portion forming a tapered shoulder portion therebetween positioned for cooperatively engaging a corresponding sized and shaped portion of said longitudinal cavity opposite said at least one annular rib;
• said rod including a threaded upper portion for cooperatively engaging said internal threads of said upper portion of said expandable mandrel, said upper portion of said rod terminating in a head for cooperatively engaging a tool.

An injector sleeve kit including an injector sleeve removal tool and an injector sleeve installation tool comprising:

• an injector sleeve removal tool for removing an injector sleeve from the cylinder head of a diesel engine between a pair of rocker arms while a head remains mounted to an engine block within a vehicle, comprising:
• a tap having a threaded cutting head formed at a distal end of a longitudinal body extending from a longitudinal shaft having a drive member at a top distal end thereof and a threaded body portion;
• an extraction nut threaded onto said threaded body portion of said longitudinal shaft;
• a bearing surface member having an axial hole therethrough disposed between said extraction nut and said longitudinal body of said tap;
• and
• and means for supporting said bearing surface member having an axial hole there through on a cylinder head;
• and
• an injector sleeve installation tool, comprising:
• an expandable mandrel comprising a hollow cylindrical barrel defining a longitudinal cavity having an upper portion including a plurality of internal threads, and a lower expandable portion including a plurality of spaced apart vertical slits, said lower expandable portion terminating in a tapered distal end defining an end cap having a center aperture formed therein, and said expandable mandrel including at least one annular rib extending outwardly from said lower expandable portion a selected distance, said an upper end portion comprising means for cooperatively engaging a tool, said upper portion including an end portion for cooperatively engaging a tool;
• and
• a longitudinal expansion rod having a tapered end, said rod having a corresponding shape and size for cooperatively engaging said longitudinal cavity of said expandable mandrel, said rod including an upper portion and a lower portion having a smaller diameter than said upper portion forming a tapered shoulder portion therebetween positioned for cooperatively engaging a corresponding sized and shaped portion of said longitudinal cavity opposite said at least one annular rib;
• said rod including a threaded upper portion for cooperatively engaging said internal threads of said upper portion of said expandable mandrel, said upper portion of said rod terminating in a head for cooperatively engaging a tool.
