Tim,
Do you have a copy of the 2018C A7CA Magazine?

Best method is in the vice!
RE: Camshaft end float - Tiger - 21-10-2018
Not got the A7CA
I am guessing I need to remove metal from the taper.
Is it best to work on the gear or the shaft ?

There is a lovely article in the Magazine that will help you - let me see if I am allowed to post it up.

Hi Tim
With only .007” endfloat I'd follow Hedd's advice to nip it up tight and see where you get to. If this doesn't do the trick, this is what I did:
I used fine valve grinding paste to lap the gear onto the camshaft taper (so removing material from both components) until the endfloat when assembled with the gear run up hard on the taper but without tightening the nut was a bit over .010”. I left the Woodruff key out when testing the gap.
Nipping the nut up tight (but not dogging it down with a breaker bar) produced the required .002” endfloat. Go steady with the lapping as it doesn't take long to remove material. This worked for me.
I haven't checked my Woodrow, but I'm pretty sure this is the method he recommends.

Tim,
In addition to the above, I now have permission to share the article from the A7CA Magazine, which I will do later if nobody else comes back with it sooner.
