Some important marks on the cam:

The gear size stamp.Attached Image

Putting the wrong size gear into your case will result in too much/too little lash. A too large gear will "walk" up the crank gear when test fitting on the case half. It's easiest to just note what size the gear is when you first break the case open, and make sure to put the same size back in that case. (Finding a -5 cam to replace the one in the pic that had corrosion/cracks in the gear was a multi-month journey...)

The pic in post 1 is of a -4 size. The numbers indicate size offset from standard, in 100ths of a mm. This is to accommodate differences in the dimensions of the crank and cam bores in the case.
