After buying a used and very rusty Conquest T42 and starting to work on the subspindle, I noticed that the "piston actuator" (see drawing) wouldn't depress the little buttons (41) because they were seized and needed WD40 and gentle coaxing with a nylon hammer to un-stick. But once un-stuck and the actuator working to depress these little buttons, the drawtube still won't turn independent of the spnidle face to allow me to thread in a collet.
Can anyone tell me what I should expect when locking the subspindle drawtube to install a collet? I've tried it with the collet open, closed, emerg on, of, and even the hydraulics on/off. For the life of me, I can't get the spindle to turn as the instructions indicate when the drawtube is locked.
The manual and drawing below suggests that by depressing the "Aux Function" button, the "piston actuator" depresses a spring-loaded button (41) that moves the drawtube engagement pin (40) from the "PIN-(engaged)" position (top illustration) to the "PIN-(free)" position (lower illustration), at which point the spindle face should rotate freely while the drawtube is held in a fixed position, thus allowing one to thread a collet into the drawtube.
Also, the drawtube certainly extends and retracts when the closer is opened/closed, so I don't think the tube is seized in the spindle bore.
I've highlighted in GREEN what I think ought to turn independent of the spindle and remainder of the collet closer assembly, but I hope someone here more familiar than I will point out what might be wrong.
Help, please, if you could.
