Start by removing all of the handles

Remove the plates from both ends of the table

Schlumberger-Private
Remove the piece circled in red

Schlumberger-Private
Now the table will slide off of the saddle

Schlumberger-Private
Loosen the two set
screws and the lead
screw nut will come
off with the lead
screw

Schlumberger-Private
Move the head to the top of the column. Loosen the bolts for the head and rotate it 90 degrees. This will expose the
bolts for the lead screw nut in Z. You can also just remove the head. It will make things easier, later

Schlumberger-Private
Take off everything on top of the column

Schlumberger-Private
Also remove everything from Z handle

Schlumberger-Private
Remove the bolts from behind the head. Screw the lead screw until the lead nut gets to the slot
in the column. Take the block off as shown, then you can pull the lead screw out from the top

At this point you’ll
need to take the
column off of the
base. It’s not a bad
idea to remove the
head first. It makes
managing this
easier

Schlumberger-Private
Unscrew the lead screw from the nut, and remove the nut, and lead screw

Schlumberger-Private
You will need to remove some material to get the new ball screw to go
in the base

Schlumberger-Private
We used a manual mill to do this….because we have one. You may have
to use a grinder. You’ll be removing 1 /4”-3/8”

Schlumberger-Private
The finish machining

Schlumberger-Private
Now you can start the installation. You will need to remove the washer
and snap ring.

Schlumberger-Private
You also need to machine this area flat to mount the X ballnut block.
Grinding it would also work.

Schlumberger-Private
Remove the .25” plate from the Y
assembly, and bolt the rest of the
assembly to the base
