Parts differences between 4 roller and 5 roller machines
 

This page was created to document differences between four and five roller machines.  I discovered that the idler adjusting rod is longer on the five roller machine.  I did not notice it until I had one off both machines together.  I will start documenting the part numbers and let you know so that if you buy parts from someon you will know if it will fit your machine or how much modification will have to be done to make it work.
