Abstract

A cam cover cap plug for use with a cylinder head assembly to fill the opening that remains when an accessory unit such as a READ utility pump is not utilized. The cam cover cap plug is preferably a one-piece, molded component formed from a plastic or a metal. The cam cover cap plug includes a back, a front, an upper surface and a lower surface. The upper surface is arched and defines a half-round configuration. The lower surface is flat and includes integrated cylinder head fasteners extending from the flat surface. The arched, half-round configuration of the upper surface provides a full and complete sealing area with the half-round opening of the cam cover formed to receive the accessory unit. The fasteners of the lower surface are preferably integrated dowels. The integrated dowels locate the cam cover cap plug base to the cylinder head of the cylinder head assembly.

First claim

What is claimed is:

1. A cam cover assembly cap plug comprising:
a body having a front, a back, an arched top, and an underside;
a pair of spaced apart arms extending from said back of said body, said arms being connected by a reinforcing bridge; and
a fastener extending from each of said arms,
wherein at least one of said front and said back includes a recessed area.

2. The cam cover assembly of claim 1 , wherein said underside is flat and includes a seal-receiving groove.

3. The cam cover assembly of claim 1 , wherein said fastener is a dowel.

4. The cam cover assembly of claim 3 , wherein said dowel is a split dowel.

5. The cam cover assembly of claim 1 , further including a front side and wherein at least one of said front and said back includes at least one reinforcing rib.

6. A cylinder head assembly comprising:
a cylinder head having an upper surface;
a cam cover cap plug having an arched top, an underside including a seal-receiving groove, a back, and a pair of spaced apart arms extending therefrom, each of said arms including a fastener for attachment to said cylinder head upper surface; and
a cam cover having an arched cut-out area for receiving said arched top of said plug.

7. The cylinder head assembly of claim 6 , wherein said underside of said cam cover cap plug is flat.

8. The cylinder head assembly of claim 6 , wherein each of said fasteners is a dowel integrally formed with said plug.

9. The cylinder head assembly of claim 6 , wherein said cam cover cap plug includes a front and wherein at least one of said front and said back includes a recessed area.

10. The cylinder head assembly of claim 9 , wherein at least one of said front and said back includes at least one reinforcing rib.

11. A cam cover assembly cap plug comprising:
a body having a front, a back, an arched top, and an underside;
a pair of spaced apart arms extending from said back of said body; and
a fastener for attaching each of said arms for attachment to a cylinder head,
wherein at least one of said front and said back includes a recessed area.

12. The cam cover assembly of claim 11 , wherein said underside is flat and includes a seal-receiving groove.

13. The cam cover assembly of claim 11 , wherein said fastener is a mechanical fastener.

14. The cam cover assembly of claim 11 , wherein each of said arms includes an integrally-formed fastener extending therefrom.

15. The cam cover assembly of claim 14 , wherein said fastener is a dowel.

16. The cam cover assembly of claim 15 , wherein said dowel is a split dowel.

17. The cam cover assembly of claim 11 , wherein at least one of said front and said back includes at least one reinforcing rib.

18. The cam cover assembly of claim 11 , further including a reinforcing bridge formed between said arms.
