SOURCE: STAIRMASTER 4600CL RIGHT PEDAL LOSES RESISTANCE AND SLIPS

http://support.nautilus.com/support/stairmaster.jsp?lid=StairMaster you can download and view all manuals here. If by drive sprocket you mean the hub that both step chains go over.....replace the entire hub. faster easier and less hassle. cost difference is about 40 dollars.

SOURCE: stairmaster 4600pt pedal falls without warning

i have the stairmaster 4000pt which was bought new in 2003. in 2007, i started experiencing the same problem, the right pedal would sometime slip and fall to the floor. i called the local fitness store and they came and replaced the hub assembly and that resolved the problem until now. The left pedal is now slipping.

Pedal slipping


Chances are the right hand clutch sprocket is failing. You can replace just the right hand side or the whole drive hub assembly. I usually find if the right hand side is gone, the left hand side is not too far behind. I will provide a link for the product I am referencing.

Why does one pedal drop on my Stairmaster Stepper but the other pedal operates correctly? Stairmaster Steppers, How to Troubleshoot when one Pedal Drops (Loses Resistance) while the Other Pedal Operates Correctly
  • If one pedal drops while the other operates correctly on your Stairmaster stepper, this problem commonly occurs when the drive sprocket on one side or the other becomes defective
  • Usually, when one drive sprocket fails, the other isn't too far behind
  • The best approach to resolve this problem is to install a new hub assembly
