5. Remove the jig.
Be careful that C and the C packings are not removed from B
and that the spline shaft is not broken when removing the jig.
* Machine is different, but
what to do is the same.
III. "B" + jig though "C"
IV. Remove the jig, being careful
not to let C separate from B
6. Insert (3) into (2).
The convex side of (3) should face upwards.
7. Insert the spline shaft (B) into the (2) and (3) assembled in
Step 6.
Be careful of direction of assembly seeing the left figure
when
inserting the shaft.
8. Fix (3) onto the spline shaft (B) with (4) and (5).
Push (3) until C goes into the step section of B (no gap
between C and B). Provisionally fix (3), aligning C with D as
shown at left.
* There should be no gap between B, C and (3).
* Be careful that (4) is straightened and that ⑤ is inserted
fully when fixing (3).
③ hollowset hole
Installing guide
(Vertical groove)
Provisionally fix (3) so that the installing guide and
the hollowset screw of (3) are aligned with the joint
D.
* Figure of nozzle installed. What to do is the same.
1. The code of the bearing case (B) should be the same as
that of the spline housing (C).
2. The code of the bearing case (B) should
face outwards. Put an Allen key into the
adjusting screw at the end of the motor shaft.
Turn the shaft until the code of (B) faces
outwards.

(Do not use a ball-
point Allen key; it can
be slide easily.)
* Apply grease to the jig.
The groove should be filled with
grease.
The joint hole
should face
outwards.

3. The shaft code of the spline housing (C) should face
outwards.
Make the code of (C) face outwards so that it faces in the
same direction as that of the bearing case (B).
4. Apply grease to the spline housing (C) slightly. The shaft
groove should be filled with grease. (See Figure 18.)

5. Insert the bearing case (B) into the spline housing (C)
lightly.
Position the mouth of the joint (with C assembled)
outwards, and insert (B) into (C), aligning the bearing balls in
the (B) shaft with the groove of (C). Be careful no to let the
bearing ball jump out.
6. Repeat Steps 1 to 4 until the total of twelve (12)
kits are created.

4. Insert the spline shaft (B) through (3) and (4).
(3) should be between (4)s. Check the direction of (3).
5. Insert the spline shaft (B) through (2) and (5).
Insert B through greased (2) and (5). Check the direction of (5).
6. Join (6) to the kit above (in Step 5) with (7) and (8).
Assembling torque : 108 +/-9 N•cm. Check the direction of (6).

extended so that the ends of the
shafts do not touch any other parts
when mounting the unit on the θ-
