Hi Nick, when you say wider race , I'm assuming that you mean the 3/4" wide 1" bore roller bearing? The reason that I suggested that the peg would/might need to be cut back is that the the rollers would be running near the edge of the track if it was not cut back (the modded peg would look something like a capital 'D' with the flat against the track edge) to get the rollers away from the substantial chamfer that cylindrical roller bearing outer tracks usually have at each side. It is the combination of the depth of the spacer and the width of the pinion bearing that will define the pinion position and therefore the maximum mesh -i.e. axial closeness to the crownwheel centreline- If you find that your new pinion is still too far out/away from the CW centre with no shims, making/getting made a slightly deeper spacer will fix that. Obviously, skimming the spacer would be the solution if you find you need a shedload of shims to get a sensible mesh.
