Steve,
I don't have a problem with the guard and thrust bearing, rather the guard and top guide bearings. When installing 1/2" blade, I'm unable to back them off enough to clear blade for tensioning without removing the guard. However, my riser block isn't perfectly aligned either :eusa_shhh
The first riser kit I received was severely outta whack :cry: They sent me a Jet kit and a can of gold paint to replace the PM kit.:lol: It was better, but required substantial shimming. A fellow NCWWer kindly volunteered to mill the original riser. He found it to be out of square, not parallel and dished :!:
With that resolved I'm soon to attempt my third install. :icon_thum
Taking hormones to encourage development of that third arm :mrgreen:
