Take side panels off, you have on the right side the alternator on top, middle pulley and bottom eccentric hub assembly on each side of the pedals are return springs disengage them. their a braket that holds the alternator loosen bolt so that the Poly-V Belt can be removed. Now inspect by hand if thier is a slippage both ways on the eccentric Hub assembly if so replace the eccentric hub assembly .
Display reads CONFIG RQRD or NTM CONFIG RQD on Stairmaster Equipment
Probable Cause
The message CONFIG RQRD or NTM CONFIG RQD appears when the console needs to be configured for the machine type it is installed. This message is common when the console has been replaced or if the settings have been changed. Message is commonly seen on various Stairmaster equipment such as bike models 3000CE, 3300CE, 3400CE, 3600RC, 3800RC and 3900RC; stepper models 4400PT, 4600PT, 4400CL, 4600CL and SC916; stepmill models 7000PT and SM916; elliptical model ClubStride 5100.
Corrective Action
Make sure the unit is in an "idle" state. "Idle" state means the console is not displaying an error or any message that requires data input. The display should basically be freshly powered up, scrolling the EKG or welcome message
Configure the console for the proper machine type by pressing Level UP, 80, ENTER
Using the Level UP or Level DOWN keys, scroll through to the proper machine type (Bike, Elliptical, Stairclimber or Stepmill)
Once the proper machine type is shown on the display select the machine type by pressing ENTER
This completes the steps necessary when your Stairmasterdisplay readsCONFIG RQRD or NTM CONFIG RQD
If you have not already done this, remove the HR grips and check for a broken terminal or loose wire. Over time, sweat can get behind the grips and cause the terminal to rust and eventual cause a bad connection.

Speed Sensor Testing and Adjustment for Stairmaster 4400cl and 4600cl Steppers
Testing and Adjustment of Stairmaster 4600CL and 4400CL Speed SensorTools Needed: Volt Meter, 7/16" Wrench
A common misconception about battery powered units, it that it only requires you to step on the pedals to power the console; when in fact the speed sensor plays a major role in powering the console.
If you step on the pedals and they fall to the floor due to the console not powering up so there is no resistance, you should check the speed sensor.
The speed sensor is mounted to the alternator and reads the speed sensor disc when the unit is pedaled producing an AC voltage. The voltage from the speed sensor can be tested at the connection of the speed sensor to the lower control board. The connection is a red and black wire. Using AC setting on your volt meter at its lowest range, place the red lead to the red wire and the black lead to the black wire. Make sure the leads of the volt meter are making a good connection. Now step on the unit and verify the voltage from the speed sensor. A good speed sensor will produce about 3 VAC before the console powers up.
If the voltage is not correct, inspect the adjustment of the speed sensor. It may be necessary to adjust the sensor closer to the speed sensor disc. Proper gap of the speed sensor to the disc is about the thickness of a business card.

Remove the mid cover and top covers and unplug the battery from the
power control board.Locate pins #1 & 2 in the end of the cable. Use a
voltmeter on the new battery to verify that the voltage is a minimum of 6.1 VDC. Connect the new battery to the proper terminals and reinstall the battery. Replace the covers and you are done. This video will show you how to remove the covers. It can be a bit tricky the first time.

Follow the steps in this video. It does not show the removal of the overlay, but gets you all the way to the point of simply peeling the old overlay off and sticking the new one on.

Sound s like it maybe the hub assembly they have a one-way bearing in them and that could be cause the problem go to
http://www.gympart.com/ or call them 1-800-496-7278 they will have the parts for your
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.
