These instructions must be followed closely, or the entire Motorized Driven Roller may be damaged beyond repair.


All machines equipped with a Regal Modsort Conveyor Module must be inspected at least monthly to ensure that no premature wear or damage has occurred. The Modsort module should be cleaned/inspected more frequently if it is noted that too much foreign material (dust, product, dirt) is building up between inspections. It is critical to specifically investigate the Axle Locks. If the Axle Locks are not properly positioned, the entire motorized driver roller (MDR) will be damaged beyond repair.

Monthly Preventative Maintenance

While the Modsort is powered off, complete the following checklist at least monthly:

  1. Remove any foreign material from on, under, and around the belts and rollers.
  2. Look for shavings or belt dust under the Modsort module that would indicate misaligned or damaged components.
  3. Look for oil leakage that would indicate faulty bearings or seals in rollers, motors, reducers, etc. 
  4. Make sure all the Spheres in the Roller-Top Belt move freely. Ensure that the Spheres are free from any tape, string, or other foreign objects.
  5. Tighten all bolted connections as needed. 
  6. Adjust the tension of the transfer belt as needed.

Axle Lock Positioning and Adjustment


It is critical to inspect the Axle Lock at least monthly for premature wear or incorrect tightening. Proper Axle Lock installation/adjustment is crucial to preserving the longevity of the MDR. If the Axle Lock is not installed correctly, the following sequence will occur:

  1. The torqued hex axle of the drive roller will wear out the Axle Lock and/or the Modsort module side frame.
  2. The unlocked axle will rotate freely.
  3. The freely-rotating axle will cause the multi-conductor wire to twist up and fail.
  4. The entire MDR will be damaged beyond repair.

Inspect the Axle Lock for Proper Positioning

  1. Power down the Modsort module.
  2. Ensure that the Roller Shaft/Cord is drawn up and fully through the Axle Lock Base Plate and Lock Plate. 
  3. Ensure the shoulder of the axle is butted against the conveyor frame.

Adjust the Axle Lock

Warning: Do not over-torque the nuts. Follow the torqueing guideline. If the nuts are torqued over 80 in-lbs, they can fail.

  1. Tighten the Base Plate Nut.
  2. Ensure the Lock Plate has been installed in the correct position. It should fit tightly against the angled edge of the Base Plate.
  3. Tighten the Lock Plate Nut.
  4. Use a torque wrench to tighten the Base Plate Nut and the Lock Plate Nut to 80 in-lbs.
