Replacing Top Y-axis Reversing Unit
1) Shut down power to the machine
normally. Remove the Y-axis (top) motor
housings using either a 1/8” Allen
wrench or a 5/16” nut driver.
2) Disconnect the motor cable from behind
the motor. Turn the locking collar counter-
clockwise and pull the plug straight out.
3) Remove the motor cable bracket from
the top mounting plate (Y-axis). A 5mm
“ball-end” Allen wrench is required.
Replace the bolt into the top bearing cart
to prevent loss of the nylon spacer
underneath the mounting plate.
