My Granger seals fit like a glove. The shims for preload seem to be black = 0.010, red = 0.005” and white = 0.0025. I experimented with removing the red and it bound up too much and with the white gone it had just a bit more resistance to turn than with the bolts loose. I assumed that wear likely had loosened it up some and I could take 0.0025” out of seems to have played out that way. Used grey sealer instead of the gasket on the side cover. I made sure that there was plenty of play with the sector gear adjustment screw to compensate the 0.030” gasket and there was. All adjusted. If you get the preloads too tight it will be hard to keep it in the road as the gear will “stick” then “pop” to the next location which likely will be more than you need and it will be a constant left to right with the wheel trying to find the perfect spot (which you can’t achieve with the steps as it pops to a new position). Those who adjusted motorcycle heads will likely know exactly how this all should feel. Just need to cut the clamp half off the 3 speed selector mechanism (not needed for the 727), wait for the grey sealer to cure overnight and fill it with 90 weight.
