Preassembly tool
View Patent ↗A tool for preassembling with an oil pan a bolt-locating isolator rail and a gasket such that the isolator rail locates a plurality of bolts for securing a flange of the oil pan to an engine block and the gasket forms an oil-tight seal between the flange and the engine block. The tool has a head, a body and a neck between the head and the body. The neck is of reduced diameter relative to the adjacent portions of the head and the body. The head has a first slot adapted to receive an aperture in the gasket. The neck is adapted to receive an aperture in the flange. The body has a reduced midsection adapted to receive an aperture in the isolator rail.

said head having a first slot adapted to receive a first aperture in the first panel,
said neck adapted to receive a second aperture in the second panel, and
said body having a reduced midsection adapted to receive a third aperture in the third panel.
2. The tool of claim 1 , wherein said neck has a shelf adjacent to said body adapted to support an annular portion of the second panel around the second aperture.
3. The tool of claim 1 , wherein said head has a top end spaced from said first slot and also has side head surface portions between said top end and said first slot, said head being insertable into the first aperture in the first panel, the top end first, to place the first aperture in said first slot, and said side head surface portions being tapered toward said top end to facilitate such insertion.
4. The tool of claim 1 , wherein said body has a bottom end and side body surface portions between said bottom end and said reduced midsection, said tool being insertable into the third aperture in the third panel, the bottom end first, to place the third aperture in said reduced midsection, and said side body surface portions being tapered toward said bottom end to facilitate such insertion.
5. The tool of claim 4 , wherein said reduced midsection has a shelf separating said midsection from said side body surface portions to support an annular portion of the third panel around the third aperture.
6. The tool of claim 1 , wherein said body has a bottom end and first side body surface portions between said bottom end and said reduced midsection, said body has second side body surface portions between said reduced midsection thereof and said neck, said tool being insertable into the second panel, the bottom end first, to place the second aperture in said neck, said first side body surface portions being tapered toward said bottom end and said second side body surface portions being tapered toward said reduced midsection to facilitate such insertion.
7. A tool for preassembling with an oil pan a bolt-locating isolator rail and a gasket such that the isolator rail locates a plurality of bolts for securing a flange of the oil pan to an engine block and the gasket forms an oil-tight seal between the flange and the engine block, the tool comprising:
an elongated, resilient, compressible member having a head, a body and a neck between the head and the body,
said neck being of reduced diameter relative to the adjacent portions of said head and said body,
said head having a first slot adapted to receive a first aperture in the gasket,
said neck adapted to receive a second aperture in the flange, and
said body having a reduced midsection adapted to receive a third aperture in the isolator rail.
8. The tool of claim 7 , wherein
said head has a top end spaced from said first slot and also has side head surface portions between said top end and said first slot,
said head being insertable into the first aperture in said gasket, the top end first, to place the first aperture in said first slot,
said side head surface portions being tapered toward said top end to facilitate such insertion,
said body having a bottom end and first side body surface portions between said bottom end and said reduced midsection,
said body having second side body surface portions between said reduced midsection and said neck,
said tool being insertable into the second aperture in the flange, the bottom end first, to place the second aperture in said neck,
said first and second side body surface portions being tapered toward said bottom end to facilitate such insertion of said tool into the second aperture in the flange,
said tool being insertable into the third aperture in the isolator rail, the bottom end first, to place the third aperture in said reduced midsection,
the taper of the first side body surface portions facilitating such insertion of the tool into the third aperture in the isolator rail.
9. The tool of claim 8 , wherein said tool is of solid construction.
10. The tool of claim 8 , wherein the neck and body are slotted and cut through from one side to the other to increase the flexibility of said tool.
11. In combination,
an oil pan,
an isolator rail for locating a plurality of bolts to secure a flange of the oil pan to an engine block,
a gasket adapted to form an oil-tight seal between the flange of the oil pan and the engine block,
a tool for preassembling the oil pan, the isolator rail and the gasket,
said tool comprising:
an elongated, resilient, compressible member having a head, a body and a neck between the head and the body,
said neck being of reduced diameter relative to adjacent portions of said head and said body,
said head having a first slot receiving a first aperture in the gasket,
said neck receiving a second aperture in the flange, and
said body having a reduced midsection receiving a third aperture in the isolator rail.
12. The tool of claim 11 , wherein said neck has a shelf adjacent to said body adapted to support an annular portion of the flange around the second aperture.
13. The tool of claim 12 , wherein said head has a top end spaced from said first slot and also has side head surface portions between said top end and said first slot, said head being insertable into the first aperture in the gasket, the top end first, to place the first aperture in said first slot, and said side head surface portions being tapered toward said top end to facilitate such insertion.
14. The tool of claim 13 , wherein said body has a bottom end and first side body surface portions between said bottom end and said reduced midsection, said body has second side body surface portions between said reduced midsection thereof and said neck, said tool being insertable into the second aperture of the flange, the bottom end first, to place the second aperture in said neck, said first side body surface portions being tapered toward said bottom end and said second side body surface portions being tapered toward said reduced midsection to facilitate such insertion.
15. The tool of claim 14 , wherein said tool is insertable into the third aperture in the isolator rail, the bottom end first, to place the third aperture in said reduced midsection, and the taper of said first side body surface portions facilitating such insertion.
16. The tool of claim 15 , wherein said reduced midsection has a shelf separating said midsection from said side first body surface portions to support an annular portion of the isolator rail around the third aperture.
