No this is the new cam & primary shaft, around 200 miles only. The cam is a good sliding fit on the shaft. It is the old shaft & cam splines that were knackered. The cam face itself on the old cam was in really nice shape. The engine sprocket cam is also in great shape, with no chips.bob wrote:Just a guess but if the old shaft splines were buggered has it jammed on the splines and someone has hammered the cam to try to remove it . A hammer is the only way I can see this sort of damage being caused .
Thinking about it, the damage is only on the overrun (anticlockwise), not the power faces of the cam, which seems counter intuitive.
Puzzling.
