Abstract
A lifter guide includes a lifter guide body having an outer surface and an inner surface that extend from a first end to a second end. The inner surface defines at least one push rod passage. A plurality of compression members are provided at the first end. The plurality of compression members project proudly from the first end. The plurality of compression members are configured and disposed to be compressed by a cylinder head to retain the lifter guide in a cylinder block. The lifter guide is devoid of mechanical fasteners.
Claims26
A lifter guide comprising:
- a lifter guide body including an outer surface and an inner surface that extend from a first end to a second end, the inner surface defining at least one push rod passage;
- a plurality of compression members provided at the first end, the plurality of compression members projecting proudly from the first end, the plurality of compression members being configured and disposed to be compressed by a cylinder head to retain the lifter guide in a cylinder block, the lifter guide being devoid of mechanical fasteners.
An internal combustion engine comprising:
- a cylinder block including a deck face and at least one lifter guide receiving portion defined in the deck face;
- a cylinder head mounted to the cylinder block at the deck face;
- and
- a lifter guide arranged between in the lifter guide receiving portion, the lifter guide includes:
- a lifter guide body including an outer surface and an inner surface that extend from a first end to a second end, the inner surface defining at least one push rod passage;
- a plurality of compression members provided at the first end, the plurality of compression members projecting proudly relative to the deck face at the first end, the plurality of compression members being compressed by the cylinder head to retain the lifter guide in the cylinder block, the lifter guide being devoid of mechanical fasteners.
A method of installing a lifter guide in an internal combustion engine, the method comprising:
- inserting a lifter guide into a lifter guide receiving portion formed in a cylinder block having a deck surface;
- mounting a cylinder head to the deck surface of the cylinder block;
- and
- compressing a plurality of compression members that project from the lifter guide proudly relative to the deck surface with the cylinder head to retain the lifter guide in the lifter guide receiving portion without a mechanical fastener.
