1.1 Disassembling the tool unclamp cylinder
※ Preparations for disassembling the tool unclamp cylinder
(1) Secure room for work between front spindle head and electric cabinet and clean up the
room.
(2) Perform the spindle orientation and pull out the tool from the spindle, if any.
(3) Manually perform the tool unclamping and use the 8mm hex wrench to remove the collet
from the spindle. Then, perform the tool clamping.
(4) Move the Z axis backward to prevent interruption by the splash guard.
(5) Pull up the W axis forward by 300mm.
(6) To facilitate the work on the tool unclamp
cylinder, tur n the spindle so that the spindle
key aligns vertically.
(7) T urn of f the machine and proceed with the
disassembling work.
1) To facilitate the disassembling of the tool unclamp cylinder, remove the spindle bearing
lubricant tank on the front tail bracket as well as the cover.
2) Use a marker pen t o mark the position of each
hose that is connected to the tool unclamp
cylinder as well as the dog switch (for sensing the
tool unclamping) before removing them.

1.4 Installing the spindle cartridge
※ Preparations for installing the spindle cartridge
(1) Clean up the spindle cartridge and other component parts to remove. (Apply grease thinly
to the installation site of the spindle head body after cleaned up)
(2) Place the spindle cartridge vertically an use the crane to lift up the boring spindle. Install it
into the spindle cartridge temporarily and check if the boring spindle fits with the drive key.
※ By factory default, the drive key is fitted with the boring spindle. So you just check if
they fit with each other , not remove them on your site.
(3) Install the gear into the spindle as appropriate and check if there is
any interruption, use a file or sandpaper to smooth the drive key or gear. If there is no
further problem, remove the parallel key and gear and clean them up for later use. Then,
insert the lock-nut and check if there is any pr oblem. If there is no problem, remove it for
later use.
(4) Insert G300 O-
installation site.
1) Installing the rear spindle bearing
Insert one of two R10751 angular contact ball
bearings into the rear spindle bearing installation
site to secure support for the rear spindle when
installing the spindle cartridge.
2) Installing the spindle cartridge
① Hook a rope between spindle cartridge and crane, and lift up the cartridge. Insert a 1.5mm
or longer wood support into the spindle and keep its balance while moving it to spindle
head. Then, insert the support in the exact center of the spindle head body.

② Since the spindle cartridge is longer at the rear side, insert B141 11133E spur gear into the
spindle body so that it fits with the drive key hole before installing the bearing housing into
the spindle head body.
※ Before installing the spur gear, apply lubricant or W40 t o the milling spindle evenly in an
attempt to facilitate the work.
③ When the spindle cartridge starts inserted into the spindle body head, insert 400mm or
longer M16×2.0 stud bolts (x4) into the tap place (for fixing the bearing housing) and adjust
the balance by tightening the nut slowly while pushing in the cartridge.
※ Care must be taken when inserting the O-ring lest that it should be damaged.
④ Keep pushing in the spindle cartridge along
with the spur gear inch by inch. By the time the
spindle cartridge starts inserted into the rear
bearing on the spindle head body, keep it
balanced while inserting it.

1.5 Installing the boring spindle
1) Fitting the bearing cap on site
① Before installing the boring spindle into the spindle cartridge, you must perform measuring
for the fitting work on the rear B14120273 bearing cap.
② Measure the outer race of each bearing of R10153 angular bearing set. (“A”)
③ Measure the outer race of B13120063 outer collar. (“B”)
④ Measure the depth of B14120262 bearing
housing. (“C”)
⑤ Use the formula below to calculate the
target and fit the bearing cap on site
accordingly. (D)
※ Sectional target size of the bearing cap:
“D” = {“C” - (“A + B”)} + 0.03mm
2) Installing the boring spindle
Hook a rope between B14111011C boring spindle and crane, and lift up the spindle while
keeping it balanced. Then, insert it into the spindle with special car e of the horizontal balance.
※ When inserting the spindle, the key should fit into the key hole with the applicable key
number and in the right direction.

adjusting the runout to below 0.03mm, impact on the lock nut using the chisel and hammer
and tighten the set-screw to fix the lock nut.
※ If you do not adjust the runout of the outer collar, installing the bearing housing may be
interrupted by the outer collar .
