Crankshaft pulleys
Does any one know the correct angle between the Z1 mark on an engine pulley and the FE mark?
I have measured it at 40 degrees but am not entirely confident. I have also measured the Z1 mark to be 90 degrees from the centreline though the locating dowel. The early 911 manual says that 1mm is 1 degree so the pulley should be 114.5mm diameter rather than 116 but I guess this is being too picky ![]() |
