Cam Thrust surface

[Bug53]

I have a new Web 86A.
I started out polishing up the thrust surface and see the cast iron actually has noticeable grain.
How far should I go or should I worry about it at all?

You should not polish it anymore than you did. That´s far enough. Those grooves help sustaining the oil film when things get busy.

Yes, don't exceed the clearance spec.
I like to center punch the edge of the bolt ends to distort the threads, keeps them from coming out, rather then locktite.

I don't really know but probably it's good.
Just a little helps a a lot more than doing nothing at all.

Or, check the thrust play then decide.

And edit the title please,

the web camsIve used were dfl coated and look like that, if you sand off the dfl you screwed up. dont sand any more.
