Lifter retainer
A lifter retainer including a central body portion connected to both a left bank of lifter retaining arms and a right bank of lifter retaining arms. The lifter retainer may be adapted to engage a key portion of one or more lifters to prevent the lifters from rotating during engine operation.
1. A lifter retainer, comprising:
a central body portion,
a left bank of lifter retaining arms attached to said central body portion, and
a right bank of lifter retaining arms attached to said central body portion,
wherein each retaining arm includes a spanning portion and a key engaging portion, and each key engaging portion of each retaining arm is adapted to engage with a sufficient running clearance a keyed surface of a respectively associated lifter.
2. The lifter retainer of claim 1 , wherein said central body portion, said left bank of lifter retaining arms, and said right bank of said lifter retaining arms are all formed from a common piece of material.
3. The lifter retainer of claim 2 , wherein said material is metal.
4. The lifter retainer of claim 2 , wherein said material is plastic.
5. The lifter retainer of claim 1 , wherein each said bank of lifter retaining arms includes at least two adjacent lifter retaining arms, wherein said at least two adjacent lifter retaining arms are spaced apart from each other defining a groove therebetween.
6. The lifter retainer of claim 5 , wherein said groove is sufficiently wide so that it allows a portion of a lifter to pass therebetween while assembling the lifter retainer to an engine block.
7. A lifter retainer, comprising:
a central body portion,
a left bank of lifter retaining arms attached to said central body portion, and
a right bank of lifter retaining arms attached to said central body portion,
wherein each retaining arm includes a spanning portion, a first key engaging portion adapted to engage a first keyed portion of a lifter and a second key engaging portion adapted to engage a second keyed portion of said lifter, and each key engaging portion is adapted to engage with a sufficient running clearance each keyed portion of said lifter.
8. The lifter retainer of claim 7 , wherein said first and second key engaging portions are opposite one another.
9. The lifter retainer of claim 1 , wherein said central body portion includes a surface adapted to engage a boss portion of an engine block.
10. A lifter alignment system,
comprising:
a central body,
a first retainer for retaining a first bank of lifters, and
a second retainer for retaining a second bank of lifters,
wherein each retainer includes a spanning segment and a first key segment, and each key segment is adapted to engage with a sufficient running clearance a keyed surface of a respectively associated lifter.
11. The lifter alignment system of claim 10 , wherein said first and second retainers and said central body are all formed from a common piece of material.
12. The lifter alignment system of claim 10 , wherein said first key segment includes a partially flat surface.
13. The lifter alignment system of claim 10 , wherein said first retainer includes at least first and second spaced retaining arms, wherein said spaced retaining arms define a groove that is sufficiently wide to allow a portion of a lifter to pass through the groove while assembling the lifter alignment system to an engine.
14. A lifter alignment system, comprising:
a central body,
a first retainer for retaining a first bank of lifters, and
a second retainer for retaining a second bank of lifters,
wherein each retainer includes a spanning segment, a first key segment and a second key segment, and each key segment is adapted to engage with a sufficient running clearance a keyed surface of a respectively associated lifter.
15. The lifter alignment system of claim 10 , wherein said central body includes a portion adapted to engage a boss portion of an engine.
