Hi Ron,
Further to Muskrats observations,
Are the cam bushes fully home in the cases?
The cam position is held by the pinion locking against the shoulder on the cam.
the distance between the cam gear and the shoulder on the camshaft (pinion fitted) should
be a few thou greater than the width of the cam bush on the timing side case
So it looks as if you have some mismatched parts???
THe cam MUST sit correctly so it will match the followers
some measuring will tell you if the bush inner or outer needs machining
Make sure the inner face of the cam pinion has not been damaged by the shoulder on the cam
HTH
