About Component Replacement and Tension Adjustment—Correct adjustment is very
important to the service life of components and operation of the machine. Your Milnor dealer
can do this work. If you know how to do this work (for example, correctly align belts and
pulleys), and you want to do it, speak to your dealer or Milnor for part numbers. Replace worn
components before you make tension adjustments.
• Machines that use rods with full threads and nuts to hold the position of the motor
base—Turn the nuts on the rods as necesary to adjust tension. Tighten the nuts.
• Machines that use a spring to hold tension on the motor base—Use the metal tube supplied
with the machine. Put the tube on the rod that the spring is attached to or remove the tube to
increase or decrease tension. Replace the spring if necessary.

How to Find a Worn Pulley
1. Broken cord—damage from a sharp object.
2. Cracks—belt is too large for the pulley.
3. Shiny side walls—oil or grease on belt.
4. The belt layers disconnect—Oil or grease.
5. Bands on side walls—dirt, particles.
6. Incorrect: The pulley is too worn.
7. Correct: The belt only touches the side
walls. You can put a thin strip of paper into
the space between the belt and the pulley.
