11. Spline Housing Assy Replacement
To replace spline housing (IC) assy, it is necessary to loosen tension on timing belt
and disconnect the spline shaft side of coupling θ. All the various operations for Z-axis motor
replacement and coupling θ replacement must be carried out including the required adjustments.
Since θ positioning upon home return is automatically the θ-axis home, no adjustment is necessary.
Reentry of MS parameters is also not required.
(1) Loosen tension of timing belt θ. (Refer to section 2- 3 Z-axis motor replacement.)
(2) Disconnect coupling θ on spline shaft side only. (Refer to section 2 - 8 Coupling θ replacement.)
(3) Loosen the 2 screws in sheeter pulley until sheeter pulley rotates freely.
(4) Loosen the 2 screws in spline thrust coupler and remove spline housing (IC) assy.
(5) Reassemble in reverse sequence. Afterwards, check spline housing Z direction. (Refer to QA Table,
Head, Spline housing Z direction.)

12. O-Ring Replacement
(1) Use a pincet or similar tool to remove O-ring from inside Z slider shaft taking care not to damage the
inside of the shaft.
(2) Insert new O-ring snugly into the shaft.
(3) After replacement, lightly coat the contact surface of the nozzle to the O-ring with grease and
join/separate with shaft several times to coat O-ring.
