Pinning of turbocharger feet with positioning pins
Fig. 9: Pin holes (P) for positioning pins
To align the turbocharger, pin holes (P) can be drilled into the engine support at the feet and the tur-
bocharger pinned. The positioning pins help to place the turbocharger in the same place again when
reassembling.
After the turbocharger has been fully assembled on the engine, the positioning pins no longer per-
form any function.
