Question about Schwinn Original Airdyne

Open Question

*O I am trying to remove the wedge pin from the left eccentric crank on my Schwinn Airdyne. The nut on the top of the wedge pin is loose and turns freely but will not come of. It just spins freely but

The nut is loose enough so I can turn it with my hand, but it does not seem to be engaging the threads at all. I keep turning it and it never makes any progress moving up the threads to come off.

SOURCE: How to disassemble crank bearing on Schwinn Mesa Mountain Bike

You wil need a couple of special tools, or be fairly creative with the tools you have.

  1. remove the dustcovers in the crank arms at the crank axle
  2. loosen the crank retaining nut/bolt.
  3. thread in a chank puller and pull the crank arms.
  4. remove the lock ring on the adjustable side of the crank axle (Requires lock ring wrench)
  5. remove adjustable bearing cup.
  6. remove axle and bearings
  7. replace or repair as needed.
Once you have it opened up ou can determine if you need new bearings or crank axle.
to assemble, reverse above procedure, insuring bearing play is minimalized.

Hope this helps.
Ed

Your computer's pickup magnet pickup sensor is not reading the magnet as you spin the bike. You probably have too much of a gap in between the magnet sensor and the magnet on your bike. Gently push the metal bracket holding your magnet sensora bit to close the gap and it should then read your magnet, calculate RPMs etc. Terpcafe@yahoo.com

I would take it in for service and let the professionals give it a tune up. You have a very good machine and I am sure that it needs to have the bottom bracket tightened and lubed. We have sold over 5000 Schwinn Air Dynes since 1981 and they are always worth fixing. So give it some love and it will be with you forever. Doctors and sports teams love these machines because it has a measured workload and they can write a program for you. We sell lots of excercise machines, treadmills etc but the Schwinn Air Dyne is the best of all of them.

There is a metal shim needed in the bike/pedal that has to be tapped in to keep the pedal tight. If you dad has used the bike for several hundred miles and/or his feet might actually bend the pedals over time (weight), it is possible the metal piece that the pedal attaches to could become bent slightly, and I have seen a few bikes, that need to be taken to the bike repair store (call a large bicycle/itness store) that has a good repair shop and they often can repair these, but rarely less than $125 for an Airdyne repair/tuneup.

Airdyne Chain Replacement with Master link

This video will demonstrate how to replace the chain with master link on a Schwinn Airdyne.

Caution: be sure to hold the handlebar as it will come loose after removal of the above parts.

How to attach book rack to 1984 Schwinn Airdyne


Remove the computer support brackets by unscrewing the bolts holding it to the bike frame. Get 3-4 inch long bolts (to replace the computer support bracket bolts) and nuts that will tighten on the other end and place the book rack support brackets in front of the large inverted U part of the bike frame. Align the holes of the book rack support with the computer support leg holes. Insert and tighten the new longer bolts with the computer legs on one side of the U and the book support legs on the other side of the U. Once you tightne the nuts, your airdyne now has both the computer and book rack on it.

http://www.fitnessrepairparts.com/diagram/113 This is an on-line link to the schematics for your Airdyne. The large nut between the handlebar (foot part) and the wheel hub are supposed to be pretty snug. Tighten the nut using a 6 or 8 adjustable wrench and tighten the nut clockwise. Be careful not to tighten too hard or the handlebar will not move at all. This is a very easy fix.

Error code 1 on schwinn elliptical 418 how do I fix it. I have replace batteries and unplugged unit. Error 1 shows up as soon as I turn unit on.


E1 error seems to indicate that the servo which controls the elliptical resistance is stuck. Here is how I fixed this (without using a "crank puller", which would be quicker by far).

You will need a very short phillips screw driver (snub nose), a long phillips screw driver, an allen key set, and crescent wrench.

- Remove the batteries from the unit.
- Remove the screws from the plastic housing (with the long phillips screw driver) on the left side. Do not forget the phillips screws at the front - they are smaller screws so don't mix them with the others. This will allow the plastic housing to flex and move around, but not come entirely off.
- Using the crescent wrench, remove the nut holding the left pedal to the crank. Carefully note the order of the washers on the crank attachment.
- Using the allen key, remove the little pedal attachment piece on the left crank arm.
- Using the short phillips screw driver, carefully reach inside the plastic housing on the top and remove the four screws holding the plastic plate on the outside of the fly wheel/crank. You will need to rotate the crank wheel to reach each of the four screws in turn on the inside of the case.
- Pull off the plastic cover for the wheel.
- Reinsert batteries and gently help the revealed cable (bottom) retract the magnet plate. In my case, the servo worked fine again after helping it retract the magnet plate that was somehow stuck/wedged.

Reverse steps to re-assemble.

Owner's manual for older Schwinn Airdyne


http://support.nautilus.com/support/schwinn/uprightbikes/prdcdovr~3550012/Schwinn+Airdyne+Exercise+Bike.jsp
Follow this link and you can download the owners manual as well as the exploded parts schematics. There will be information about the different years. other than the consoles they have remained the same for 20 + years. If you ever need to replace the bottom bearing be sure to get the lock ring as well. It changed from left hand thread to right. Thats it. You can also upgrade the console to the newer version. A little expensive but with proper care a 20 year old Airdyne will last till the frame rusts out from under it.
