I have a 93 mori mv40 with 20,000 rpm cat40 spindle with high and low range, that has been sitting for a bout 2 years, it made a small move from my old shop to new about a year ago, probably only a few hundred feet move, no trailer involved. Now it will only run the spindle in high range. When it is in low range it won’t start up do to the spindle brg not preloaded alarm. It also will not do a spindle orientation, of release the tool from the head... any ideas???
