Camshaft removalsCamshaft removalsOnce again, I turn to the experts on how to solve my problem of removing the right camshaft. Left side came out after some aggressive persuasion. It seemed like the splined end of the shaft was "stuck" in the camshaft sprocket. Now the right one won't let go. What I can't figure out is the purpose of the camshaft locking bolt. Does it lock the right camshaft to the sprocket? I have the nut loose but tapping on the treaded end results only in the whole camshaft assembly moving in the head bearing bores. How is the camshaft separated from the sprocket?
The camshaft locking bolt has a tapered head that expands the id of the camshaft a few thousandths to grip the center. Loosen the nut on the bolt and tap(lightly) on the end of it to release it from the taper. I unscrew the nut until it is flush with the end of the bolt and tap it with an eight ounce hammer.

You've got to release that taper before you can get the cam apart and the cam is pretty bullet proof.
As DJM says - run the nut off so that it is flush with the end of the thread and give it firm blows with a (2lb) hammer. The taper will give way and the nut will move up to the end of the cam. If it doesn't move, you haven't hit it hard enough..... G
