Carefully insert the RAD driveshaft into the inner spindle and lift the unit upward as far as it will go. Rotate
the RAD output shaft until the driveshaft key is lined up with the inner spindle keyway. This will be visible
through a small window on the left side of the RAD hub. At this point, the RAD will not fall out, so holding
it in place is not required.
There are two adjustable keys on the RAD mounting hub that need to be lined up with the keyway
notches of the outer spindle. It is not possible to see that these are aligned, so it is a little bit of trial and
error when installing the unit. If the unit has never been installed on this particular machine, it would be
best to temporarily remove these keys during the initial installation.
Before rotating the tool engage the drawbar to finish installing the unit, using a small shim under the inner
spindle drive key in case it is not perfectly aligned to prevent bending of the key. A small flat screwdriver
works well.
NOTE: Verify that the RAD hub is against the bottom face of the outer spindle. If not, the inner, or
outer keys, are not lined up, repeat the prior procedure until it is correct.
At this point, the RAD must be aligned so that the hub face is 90° to the travel of the X axis. With an
indicator touching the output face of the RAD, move the Y axis back and forth to see the amount of error.
There are two (2) adjusting set screws and an adjustment block on the RAD hub. The two set screws
push against the adjustment block to turn the head left or right. The adjusting block is keyed to the outer
spindle. The two screws mounting the adjusting block to the hub need to be slightly loose.
