SOURCE: 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.

SOURCE: 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.

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.

SOURCE: I need to tighten the chian on my schwinn airdyne.

Two places to tighten the chain and it requires you to loosen the nuts on BOTH sides of the bike, almost at the same time. Start at the fan wheel (top) of the bike. First thing you need to do is to loosen the little nut at the hub of the fan wheel on both sides. Unscrew it almost to the point of taking it off, but leave it screwed on the end of the bolt so it will stay on the bike. Then use an adjustable wrench to loosen the nut a bit on one side and then do the same on the other side OR use both hands and loosen both at the same time by unscrewing with adjustable wrench in opposite directions on both sides. Once the wheel is loose, you want to sit in front of the bike and pull both of the large nuts at the same time toward you and the chain will tighten. The goal is to have the fan wheel centered and for you to be able to see about 1/4" inch of clear gap behind the nut on both sides. Then use your fingers to tighten the nuts to the frame just enough until you can use the adjustable wrench again. I have sometimes used a flat head screwdriver to insert into the gaps to prevent the chain from loosening up. The tighten the nut on both sides of the bike. Be sure you tighten the little nuts as well (they are called chain tensioners). That SHOULD do the trick. However, if your bike chain is still too loose, you need to do the same for the chain at the pedal area, That requires the same thing all over again, but in most cases, the chain loosens at the top part of the bike (fan wheel place). However, if you do work on the pedal area, you want the chain to be pushed toward the fan and not toward the **** side of the bike. It may sound crazy but that's the only way to tighten the chain. give me a thumbs up with my solution.

Pedals turn freely with no resistance. Is there a broken belt or chain?


What think you if its a problem with the crank axle connection on the driver blade if you can not optical see a problem with chain or belt, then it must be this kind of problem or a pedalforce-adjuster can be broken or just not set

How to replace a chain with master link on a Schwinn Airdyne


Airdyne Chain Replacement with Master link

This video will demonstrate how to replace the chain with master link on a Schwinn Airdyne.
  • First remove the cotter pin and clevis pin from the user's right handlebar. Then lower the connecting arm and handlebar.
Caution: be sure to hold the handlebar as it will come loose after removal of the above parts.
  • Remove the connecting arm and pedal and crank arm by removing the wedge pin. To simplify this process loosen the nut and tap on it with a small hammer until the pin is loosened.
  • Remove the nut, wedge pin, crank arm and connecting arm.
  • Next remove the chain guard; there are three screws attaching it as shown in the video.
  • Remove the chain by locating the master link. Remove the lock pin and the cover, and then disconnect the chain.
  • Place the new chain on the sprockets as shown in the video.
  • Install the master link, cover and lock.
  • Re-install the chain guard and attaching screws.
  • Re-assemble the connecting arm to the handlebar and eccentric.
  • Be sure the brass bushing is installed in the front inner side of the connecting arm before installing the clevis pin and cotter pin.
  • Install the crank arm with pedal.
Be sure when completing this step that the crank arm is installed in the opposite position as the users left side crank arm.
  • Install the nut onto the wedge pin and tighten.
  • This completes the procedure.

How To Identify the Model of a Schwinn Airdyne Exercise Bike

  • We'd like to share some characteristics of the Schwinn Airdyne bikes that can be used to help you identify the model of your Airdyne bike.

Does your Airdyne bike have two chains or a chain and a belt?

  • AD3, AD4 bikes have two chains.
  • AD Pro/Comp and AD Evolution Pro/Comp bikes have a chain and a belt.

How do the crank arms attach to the Airdyne, by wedge pin or bolt?

  • AD3, AD4 and certain AD Pro/Comp crank arms attach by wedge pin.
  • Certain AD Pro/Comp bikes have crank arms that attach by bolt.
  • AD Evolution Pro/Comp bikes have crank arms that attach by bolt.

Squeaking belt on airdyne bike


I love my Schwinn Evo Comp AirDyne. After 2 years it suddenly developed a bad squeak and about .5" of increased play in the pedals (ie the pedal could rotate back and forth about .5" before turning the fan). Both these symptoms were caused by a broken spring in the chain tensioner. (Schwinn pn 13000371. See part 80 in blowup 5 of http://www.fitnessrepairparts.com/diagram/114 ~$9).
To replace this:
  1. disconnect the right hand (as you sit on it) connecting arm (ie the piece that connects the pedal to the big handle) from the lever arm (ie the big handle you pull back and forth) by removing the connecting bolt with an Allen head wrench and an adjustable wrench. Note the order of the three internal washers as you remove the connecting bolt. Rotate the connecting arm towards the back of the bike to get it out of the way.
  2. remove the four phillips head bolts that hold down large right hand plastic cover. With the connecting arm out of the way this cover can be pulled far enough out to gain access to the chain tensioner.
  3. remove the broken spring and replace it. I fashioned a similar spring with less tension which seems to work as a kluge. The original spring broke at the outermost loop, so I might have been able to reuse it by just bending down another loop.
  4. could lube the chain while you are in there, but you can also lube it anytime from the other side
  5. put it all back together

The pedal mechanism is loose when try to ride


Can you be more specific? There can be several reasons for this. Pedal arms can be worn out, hub in fan can need overhauling. Does the chain move with the pedals? Are the pedal arms loose or the pedals themselves? Pedal hub could also need overhauling. If the overhauling seems to be the issue, best bet would be to take the machine to a local Bike shop, If you're pretty handy, and can do the repair yourself, give me more specific details and I can suggest better instructions on repair.
