Service manual

Re-assembly:

11) Remove the front two bearings from the new bearing cart, as in steps 9 and 10

above, and fit the cart over the Y-gantry beam so that the eccentric adjustable

(missing), bearings are towards the front.

12) Insert each bearing axle back into the cart, and through the hub of the bearing. Make

sure the bearings are properly aligned with the steel tracks, and that the bearing

axles are fully inserted into the bearing cart. The head of the axles should be nearly

flush with the cart surface when inserted fully.

13) Adjust the eccentric pivot axles with a 5mm Allen wrench for proper tightness to the

bearing tracks, then tighten the locking set screws with a 2mm Allen wrench. Roll the

cart up and down along the gantry repeatedly to check for smooth and quiet

operation.

14) Insert the top end of the belt and

coupling plate into the bearing cart,

and partially insert the two coupling

screws. Do not tighten the screws

yet.

15) Insert the lower end of the belt and

coupling into the bottom edge of

the cart. Insert the coupling

screws, align the belt with the

center mark on the cart, and

tighten the screws securely.
