Claims
- 1. A rocker arm assembly for mounting on a rocker carrier in an internal combustion engine, the rocker arm assembly comprising:a rocker arm comprising a push rod cup, an aperture, a pivot ball cup, a pivot foot cup, and a pivot foot member being cooperatively fastened by a pivot foot clip to the pivot foot cup; a fulcrum plate; a retaining clip; a pivot ball able to, in cooperation with the retaining clip, cooperatively connect the fulcrum plate and the rocker arm; whereby the pivot ball provides a pivot point for the rocker arm to pivot about and thereby actuate a valve.
- 2. The rocker arm assembly of claim 1, wherein the fulcrum plate is an end fulcrum plate.
- 3. The rocker arm assembly of claim 2, wherein the rocker arm is an intake rocker arm or an exhaust rocker arm.
- 4. The rocker arm assembly of claim 1, wherein the rocker arm actuates the valve via the pivot foot acting on a valve bridge.
- 5. The rocker arm assembly of claim 1, wherein the fulcrum plate is a dual fulcrum plate or an end fulcrum plate.
- 6. The rocker arm assembly of claim 5, wherein the rocker arm is an intake rocker arm or an exhaust rocker arm.
- 7. The rocker arm assembly of claim 6, wherein the fulcrum plate is 10 millimeters thick.
- 8. The rocker arm assembly of claim 7, wherein the fulcrum plate comprises a hold down bolt passage and a head bolt passage.
- 9. The rocker arm assembly of claim 1, wherein the fulcrum plate is a dual fulcrum plate.
- 10. The rocker arm assembly of claim 9, further comprising an intake rocker arm and an exhaust rocker arm.
- 11. The rocker arm assembly of claim 10, wherein the intake rocker arm and exhaust rocker arms actuate valves on different engine cylinders.
- 12. The rocker arm assembly of claim 11, wherein the dual rocker arm fulcrum plate is 10 millimeters thick.
- 13. The rocker arm assembly of claim 12, wherein the dual rocker arm fulcrum plate comprises a hold down bolt passage and a head bolt passage.
- 14. The rocker arm assembly of claim 3, wherein the end rocker arm fulcrum plate is 10 millimeters thick.
- 15. The rocker arm assembly of claim 14, wherein the end rocker arm fulcrum plate comprises a hold down bolt passage and a head bolt passage.
- 16. A rocker arm assembly for mounting on a rocker carrier in an internal combustion engine, the rocker arm assembly comprising:a rocker arm comprising a push rod cup, an aperture, a pivot ball cup, a pivot foot cup, and a pivot foot; an end fulcrum plate; a retaining clip; a pivot ball able to, in cooperation with the retaining clip, cooperatively connect the end fulcrum plate and the rocker arm; whereby the rocker arm pivots via the pivot ball to appropriately actuate a valve bridge.
- 17. The rocker arm assembly of claim 16, wherein the dual fulcrum plate comprises a hold down bolt passage and a head bolt passage.
- 18. A rocker arm assembly for mounting on a rocker carrier in an internal combustion engine, the rocker arm assembly comprising:a rocker arm having a push rod cup, an aperture, a pivot ball cup, a pivot foot cup, and a pivot foot; a fulcrum plate; a retaining clip; a pivot ball able to, in cooperation with the retaining clip, cooperatively connect the fulcrum plate and the rocker arm; whereby the pivot ball provides a pivot point for the rocker arm to pivot about and thereby actuate a valve bridge via the pivot foot.
- 19. The rocker arm assembly of claim 18, wherein the fulcrum plate is a dual fulcrum plate or an end fulcrum plate.
- 20. The rocker arm assembly of claim 19, wherein the rocker arm is an intake rocker arm or an exhaust rocker arm.
- 21. The rocker arm assembly of claim 20, wherein the fulcrum plate comprises a hold down bolt passage and a head bolt passage.
- 22. A rocker arm assembly for mounting on a rocker carrier in an internal combustion engine, the rocker arm assembly comprising:an exhaust rocker arm; an intake rocker arm; a dual fulcrum plate; at least one retaining clip; at least one pivot ball able to, in cooperation with the at least one retaining clip, cooperatively connect the dual fulcrum plate and the exhaust and intake rocker arms; whereby the exhaust and intake rocker arms each pivot via a corresponding pivot ball to appropriately actuate a corresponding valve bridge on different engine cylinders.
- 23. The rocker arm assembly of claim 22, wherein the exhaust and intake rocker arms each comprise:a push rod cup; an aperture; a pivot ball cup; and a pivot foot.
- 24. The rocker arm assembly of claim 23, wherein the dual fulcrum plate comprises a hold down bolt passage and a head bolt passage.
- 25. The rocker arm assembly of claim 16, wherein the rocker arm is an intake rocker arm or an exhaust rocker arm.
