TIP:
When mounting the RDU, the slot in the drive hub must align with
the lead screw slot in the bar.
FIGURE 6. ALIGN THE DRIVE HUB SLOT WITH THE LEAD SCREW
1. Inside the torque arms are mounted to (radial direction is optional) RDU housing.
2. Mount the hydraulic motor to the RDU.
3. Slide the RDU onto the boring bar.
4. Make sure the key slots in the boring bar and the RDU drive hub are aligned.
5. Push the bar drive key into the key slot.
CAUTION
The rotational drive key must be in place before operating the
boring bar. Failure to do so may damage the machine.
6. Adjust the shaft collars into place in the RDU. Tighten the clamping screws to
lock the shaft collars to the boring bar.
7. Secure the torque arms to insure the RDU does not rotate when energized.
WARNING
Loose torque arms can seriously injure the operator and damage
the machine. Secure the torque arms to a stationary structure
strong enough to withstand the full torque of the RDU.
