Re: TR Cam Lobes

["Greg Solow" <gregmogdoc@surfnetusa.com>]

In the TR-2,3,4 blocks, all of the tappet bores are offset from the
centerline of each cam lobe. They are offset in pairs in opposite
directions. So to grind the cams properly, 4 lobes must be tapered in one
direction and the other 4 must be tapered in the other direction. This
requires 2 setups on the cam grinder. There are not many cams ground this
way. Having it done properly does make a difference in longevity, especially
with high spring pressures.
