Abstract:
1. A seal alignment system comprising: an engine block formed from a first material having a first coefficient of linear thermal expansion; a cover component formed from a second material that is different from the first material and has a second coefficient of thermal expansion that is different from the first coefficient of linear thermal expansion, wherein the cover component is spaced apart from the engine block and defines an annular channel therein and a first bore therethrough; a crankshaft protruding from the engine block and extending through the first bore, wherein the crankshaft is rotatable about a central longitudinal axis and has an outer surface; an annular seal spaced apart from the engine block and defining a second bore therethrough; and an alignment device configured for coaxially aligning the annular seal with the central longitudinal axis so that the crankshaft extends through the second bore and the annular seal abuts the outer surface; wherein the alignment device includes a tube defining an interior cavity and having:
