The sample casting for the crankcase lower section just came in. This part contains the crankshaft lower bearing caps, oil pump/filter and drive system, and the transmission and clutch. Although it looks visually more complicated than the crankcase top, it is a simpler piece to cast in that there is only one internal passages requiring a buried core, namely for the oil pump pressure area.

The QC process used on this part will be the same as for the crankcase top:
- scan



- overlay to CAD to verify fidelity to the CAD model.


This sample part was dimensionally excellent. There are a couple of areas I may modify after going through the part's CNC programming process. I'll know more as the part moves through the various machining stages.
That's all for now.

nice shirts! :D
