A bearing housing (12) for a turbocharger (10) includes a split (60) defining a first bearing housing segment (62) and a second bearing housing segment (64). At least one channel (74, 84) for transporting fluid within the bearing housing (12) crosses the split (60) such that the channel (74, 84) extends within the first bearing housing segment (62) and the second bearing housing segment (64). A dowel (82, 92) having a hollow interior is inserted in the channel (74, 84) to align the first and second bearing housing segments (62, 64) and allows fluid to flow through the channel (74, 84).

The bearing housing (12) as set forth in claim 3 wherein said collar (70) extends in an axial direction and protrudes from a face (68) of said second bearing housing segment (64), said face (68) of said second bearing housing segment (64) is generally parallel to and directly abutting a face (66) of said first bearing housing segment (62). 5. The bearing housing (12) as set forth in claim 4 including a clamp (72) securing said first and second bearing housing segments (62, 64) together, wherein said clamp (72) extends around an outer circumference of said bearing housing (12) and is aligned in said axial direction with said split (60). 6. The bearing housing (12) as set forth in claim 5 wherein one of said first and second portions (76, 78, 86, 88) of said at least one channel (74, 84) includes a step (80, 90) in a diameter of said at least one channel (74, 84), and wherein said dowel (82, 92) is seated against said step (80, 90), thereby positioning said dowel (82, 92) within said at least one channel (74, 84) in said axial direction. 7. The bearing housing (12) as set forth in claim 5 wherein a first portion (76) of a first channel (74) includes a step (80) in a diameter of said first channel (74), and wherein a first dowel (82) is seated against said step (80), thereby positioning said first dowel (82) within said first channel (74) in said axial direction. 8. The bearing housing (12) as set forth in claim 7 wherein a second portion (88) of a second channel (84) includes a step (90) in a diameter of said second channel (84), and wherein a second dowel (92) is seated against said step (90), thereby positioning said second dowel (92) within said second channel (84) in said axial direction. 9. A turbocharger (10) including an electric motor (38), said turbocharger (10) comprising: a bearing housing (12) having a split (60) defining a first bearing housing segment (62) and a second bearing housing segment (64), wherein said bearing housing (12) defines a motor cooling cavity (50) between an outer circumference of the motor (38) and an inner circumference of said bearing housing (12);at least one channel (74, 84) for transporting fluid within said bearing housing (12), wherein said at least one channel (74, 84) crosses said split (60); anda dowel (82, 92) having a hollow interior inserted in said at least one channel (74, 84), wherein said dowel (82, 92) aligns said first and second bearing housing segments (62, 64) and maintains an angular orientation of the first and second bearing housing segments, and allows fluid to flow through said at least one channel (74, 84). 10. The turbocharger (10) as set forth in claim 9 wherein a first portion (76, 86) of said at least one channel (74, 84) extends within said first bearing housing segment (62) and a second portion (78, 88) of said at least one channel (74, 84) extends within said second bearing housing segment (64), and wherein a first portion of said dowel (82, 92) is disposed in said first portion (76, 86) of said at least one channel (74, 84) and a second portion of said dowel (82, 92) is disposed in said second portion (78, 88) of said at least one channel (74, 84). 11.
