12) Position the bearing cart back onto the frame rails, making sure that the rear
bearings are properly engaged with the rear rail. Insert one of the front bearings and
axles into the cart, and tighten the eccentric pivot and set screw enough to hold the
cart in place. Insert the second front bearing, and then adjust and tighten both
eccentric pivots and the corresponding set screws. Move the cart back and forth
several times to ensure that the bearings are all rolling smoothly on the tracks.
13) Move the cart and standoff block back to the left and align to the gantry squaring tab.
Re-insert the flat head tab bolt first, and tighten it securely into the threaded hole in
the standoff block. Also align the slot at the base of the cable channel with the
mounting bolt on top of the standoff block.
14) Insert the two large bolts back into the lower end of the gantry beam, and tighten
securely to the T-nuts in the standoff block channels.
15) Align the rear adapter plate to the bearing cart, then insert and securely tighten all 4
bolts which were removed in step 6 above.
16) Position the cable channel so that it is parallel with the gantry beam over its entire
length, then tighten the mounting bolt at the bottom of the channel. (see photo)
17) Re-assemble both felt pad holders to the bearing cart. Make sure all pads are clean,
lubricated, and properly aligned with the frame rails.
18) Re-mount the plastic bearing guard and bumper-spring assembly. Plug the motor
cables (P201 & P203), back into the controller box, power up the system, and make
test cuts.
