hi guys,
i just bought an old mori seiki sl3b with mori yasnac control.
there is a 5c collet closer installed and i want to install the 10" power chuck that came with the machine. the manual does not mention this and i want to make sure i don't destroy anything before i do it. first of all there seem to be no way of locking the spindle so it i hard to get any leverage opening the 6 allen bolts. the best i could get was to run the spindle at lowset speed when in fact it does not move at all. so far i only bent the allen wrenches though. the bolts do not move at all. if i ever get them off, i am sure there must be some way of getting the chuck back plate off the chuck. otherwise i cant install the 6 bolts again. lastly there should also be some connection for the hydraulic pressure.
andy advise is highly appreciated!
sorry about no captal letters. i am writing on a broken keyboard.
