Connecting Rods

This is the schematic of the crankshaft and camshaft showing the clearance for the connecting rods. The stroke is 40mm the connecting rod is 91mm between centres.

I plan to cut a trial connecting rod and dummy piston from aluminium to check clearances. The connecting rod big ends actually run between the cam lobes for each cylinder so the mock-up con rod will be used to confirm the clearance.


This was taken as a screen capture from AutoCAD. The horizontal blue dashed lines are the Y limits of the mill and the red dashed lines are the Mill table centres.
