I have taken the bike apart and the belt, etc. seem to be working well. I think that it is the crank assembly that needs to be replaced but I can't seem to figure out how to remove the foot crank arms and get the crank assembly free. How can I fix this and is it worth it because the bike is so old and the part is so expensive?
Dear Sir:
Please do the following:
Use aflat screwdriver to unseat the tabs that hold the front top cover in place.This will expose the flywheel and pedal arm connection points. Rotate theflywheel by hand and determine whether lubrication will accomplish the repairs.If the bearings are exposed, use a grease gun with an extension nozzle and lubricateboth bearings with lithium grease. If the bearings are damaged or sealed,proceed to the next step.2
Removethe front and side covers on the main frame. Hold the flywheel with one handand use a box wrench to loosen the bolts that secure the pedal arms at eachside of the flywheel. Pull the arms away from the flywheel and remove thebearings from each side.3
Test thebearings as before. Lubricate exposed bearings with lithium grease andreinstall them. Sealed bearings must be replaced. Reattach the pedal arms tothe flywheel. Replace the main frame covers and front top cover to complete therepairs.sincerely. God bless you.

If console lights up but doesnt respond when buttons are pressed, you more than likely have a console problem. Key pad issue would be my best guess.
SOURCE: Elliptical magnetic resistance not fully assembled.
There are 2 springs on this unit one pushes the eddy magnets towards the flywheel one is used to pull it away. Find the pictures and parts list here. http://www.iconservice.com/pdf/NEL70950.pdf
SOURCE: Calibration Mode for nordic track treadmill model
Hello there, The calibration mode for a nordictrack is as follows.
With the safety key out, hold the stop and speed up arrow at the same time while inserting the key. Release the buttons. You will then be in diagnostics.
You then press the stop button one time.
If you are trying to calibrate the incline you just need to hit the incline up button and the machine will do an incline calibration. The unit should go all the way to the top and return to the bottom when completed.
If you need to calibrate the speed you will need to press and hold the speed up button on the console until the display reads 85. The machine should then be running at its maximum speed (either 10 or 12 mph depending on the unit)
The display will show a speed on the console and should be within .3 of the maximum speed.
If it is not then it will need to be adjusted using a potentiometer on the control pwb.
To access the control pwb open the hood cover. Should be 3 screws in the rear of the cover and 2 screws on the bottom of the unit.
Once inside the cover locate the control pwb. On the control pwb there will be a yellow/orange potentiometer. This is the adjusting part.
Use a non-metallic phillips head screw driver to adjust the potentiometer either clockwise for faster or counterclockwise for slower.
Hope this helps!
Good Luck! Tim

Remove
the bolts or screws securing the console to the upright assembly. Lift the
console and confirm that the cable connections are secure. Remove the cover
from the console's battery bay and install a fresh set of batteries. Replace
the battery cover.
2
Detach
the ends of the pedals from the crank axles. Remove the left and right disc
shields and side shields. Inspect the interior of the base unit and locate the
flywheel.
3
Inspect
the flywheel as it turns. Locate the magnet installed on the flywheel. Turn the
flywheel until the magnet passes in front of the nearby reed switch. Loosen the
screw securing the switch in place. Rotate the switch to reduce the gap between
it and the magnet. Tighten the screw.
4
Replace
the left and right disc shields and side shields. Reattach the ends of the
pedals to the crank axles.
Finally tight the flexible cord form keypanel vs display board and then tight the display board vs lower board.
See if you can meassure +5VDC from lower board to display board.
see the block diagram for your final diagnostic.
Sincerely. Merry Christmas.

Remove the screws or bolts securing the ends of the pedals
to the crank axles. Slide the ends of the pedals off the axles. Remove any
screws or bolts securing the left and right disc shields to the base unit. Pull
or pry the disc shields off the base unit and set them aside.
Step 2
Remove any screws or bolts securing the left and right side
shields to the base unit. Detach the side shields and set them aside. Examine
the interior of the base unit and locate the drive belt.
Step 3
Pull the drive belt free of the crank pulley, flywheel and
any other pulleys. Discard the old drive belt and install a new belt in its
place. Turn the crank axles by hand to confirm that the belt will turn smoothly
when the device is in use.

Kneel next to the left side of the elliptical's base. Use the Phillips screwdriver to tighten the two screws located in the center of the left pedal.
2
Use the Allen wrench to remove the bolt securing the left pedal arm to the pedal leg and body arm. Use the Phillips screwdriver to remove the screw securing the rear end of the pedal leg to the crank arm.
3
Pull the end of the pedal leg free of the crank arm. Wipe the crank arm clean, then apply a fresh coating of machine grease or silicone lubricant. Replace the end of the pedal leg back onto the crank arm and use the previously removed screw to secure it back into place.
4
Join the front end of the left pedal arm to the ends of the pedal leg and body arm. Use the previously removed bolt to connect the pieces together.
5
Move to the right side of the elliptical and repeat the above steps on the right pedal arm.
