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.
