Are all camshafts hollow?

[Guest]

Mine are hollow I a wondering if all Suzuki's have hollow shafts.

shameless bump

Haven't cut one open to check. Or did you mean like a hollow axle, like a pipe, you can look in one end and see out the other?

[Mekanix]

I'd say there is a mix of both.

I've seen some with a tube put inside and welded on each end for when the cam crack's in half.

They look as though they were machined with a hole running the full length as if they are a pipe.

A lightening method no doubt.

Yeah like a hollow axle.

Yeah like a hollow axle.

I believe it's done to strengthen the cam, rather than lighten it actually.

Norton cams were made both solid and hollow. I snapped one once, but I don't remember which it was.

no, all suzuki camshafts are not hollow
