Caterpillar Excavator 335

To ensure that the table will perform accurately, there are a few points of inspection that should be performed occasionally. There are basically four points of interest when inspecting the table: the platter face and I.D., runout, backlash and popout.

Platter Face Runout: To check the platter runout, mount an indicator to the body of the table. Position the stylus on the face of the platter and index the table 360 degrees (3600). The runout should be 0.0005" or less.

Platter I.D. Runout: To check the platter I.D. runnout, mount the indicator to the body of the table. Position the stylus on the through-hole in the platter and index the table 360 degrees (3600). The runout should be 0.0005" or less.

Backlash Between Worm And Gear: To check the backlash between the worm and gear, the air supply must first be disconnected. Place a magnet on the face of the platter at a radius of 4". Mount an indicator on the body of the table and position the stylus on the magnet. Use an aluminum bar to rock the platter back and forth (apply approximately 10 ft-lb while testing). Backlash should be between 0.0001" and 0.0006".

Popout: To check popout, first disconnect the air supply from the unit. Then, index the table 360 degrees. Mount an indicator to the body of the table. Position the stylus on the face of the platter and zero the dial. Connect the air supply and read the popout from the indicator dial. Popout should be between 0.0001" and 0.0005";

Warning: Adjustments to the tilting rotary table are not field serviceable. If out of tolerance, contact your HAAS dealer.

Backlash in the system can be compensated for by the use of Parameter 15. Contact HAAS service department for details.

Lubrication: The table is lubricated with MOBIL SHC 630. Do not let the oil level drop below the sight glass level.

Check if the oil level is above the sight glass level

If the oil level is low, fill the table through the pipe plug in the middle-top of the body. Fill to the top of the sight glass. Do not overfill!

If the oil is dirty, drain and refill with fresh oil (SHC-630). If the rotary axis needs to be refilled with oil, please contact HAAS for information. Do not attempt to refill!

Clean up: After use, it is important to clean the rotary table. Remove all metal chips from the unit.

Check if all metal chips are removed from the unit

Warning: DO NOT SUBMERGE THE UNIT IN COOLANT

Coolant lines on the work piece spraying away from the rotary table
