Abstract
A method of assembling a bearing house for a rotary shaft, such as a camshaft, comprising a bearing cap secured to a relatively massive component, such as a cylinder head. The bearing cap and the massive component afford respective semi-circular recesses which cooperate to define a circular hole in which the rotary shaft may be received. The method comprises connecting the bearing cap to the massive component, deforming at least spaced portions of the bearing cap into intimate contact with the massive component so as to produce a unique relocation position, boring the circular hole in the bearing cap and the massive component, removing the bearing cap, inserting the shaft into the semi-circular recess afforded by the massive component and reconnecting the bearing cap to the massive component.
Claims6
A method of assembling a bearing housing for a rotary shaft comprising a bearing cap and a relatively massive component, said bearing cap and said massive component defining respective semi-circular recesses, which cooperate to define a circular hole in which said rotary shaft may be received, the method comprising:
- connecting said bearing cap to said massive component,
- deforming at least two spaced portions of one of said bearing cap and said massive component, deforming at least two spaced portions of one of said bearing cap and said massive component into intimate contact with the other of said bearing cap and said massive component, so as to define a unique relocation position for said bearing cap with respect to said massive component, wherein said at least two spaced portions comprise two projecting lugs on opposite sides of said circular hole,
- boring said circular hole in said bearing cap and said massive component,
- removing said bearing cap,
- inserting said shaft into said semi-circular recess of said massive component, and
- reconnecting said bearing cap to said massive component.
