My first thought about the chain continuuin to become loose, is that you need to loosen the nuts on the back wheel, and pull the wheel (while the chain is still attached to bot hsprockets) in order to remove any slack. If it's a continuous issue, chances are that back tire keeps migrating forward because those nuts aren't tight enough.

To the pedal issue-If the pedals are wobbling or vibrating because the aren't snug while on the pedal bar (the bar that the pedals revolve around) it is probably because the peddals are too large. Try buying a new set of pedals. If they are loose and trying to slip off of the pedal bar and if you have tightened the nuts that keep the pedal on the pedal bar and they are continuing to become loose, it could be that you need to use locking nuts.

A quick fix to solving loose pedals is to add washers to the end of the bar until the washers are flush up against the pedal and the nut.

Happy pedaling!

Can you adjust the tension on the wheel?


What sort of tension?
Rim loose on spokes: evenly tighten the spokes to add tension ( very high skill required to keep the rim true. Pro help should be sought)
Too much wheel side play: tighten the wheel to frame axle bolt (unless the bearing is gone, then you'll need new hub bearings).
Chain tension too loose: Move the rear wheel away from the pedals by loosening the axle bolt, pulling back to remove most (but not all) or the slack from the chain. Pay attention to the alignment of the wheel in the frame. Tighten the nuts back down

Chain keeps poppin off


These are the instructions for adjusting the chain. They are taken directly from the manual available at http://ep.yimg.com/ty/cdn/razorama/e100e200e300manual.pdf

To adjust the chain:
1. Loosen the axle
2. Loosen the brake anchor (this is attached with the small bolt in the long slot on the left side of the rear fork)
3. Tighten the tension adjusters on the axle 1/8 to 1/4 turn to tension the chain. Tighten both adjusters the exact same amount to maintain the wheel alignment.
Note: this system of adjusters is common to motorcycles and BMX
bicycles so I your are not familiar with it, if you know anyone who is,
they would not have a problem adjusting it for you.
Chain tension: The chain should be "just not-quite snug" in other
words, not taut or sloppy loose. BE CAREFUL NOT TO ADJUST TOO TIGHT. The tensioning system can easily impart too much tension and snap the chain or bend the motor output shaft. Turn the adjusters 1/8 to 1/4 turn at a time and recheck the tension each time.
4. Once the tension is good, tighten the axle and brake anchor bolt. Test run the scooter. Readjust as needed.

I have a new 455 rancher chainsaw husky 20inch bar chain keeps coming off new chain


You may have a bent bar, or you could be putting the chain on a little too loose. Perhaps the chain is not getting lube ?
Possible that the chain tentssioner and or adjustment is loosening up as you are using the unit. Other than that maybe a defective new blade ?

We changed the pads, rotors, drums and shoes on our 2001 montana, after we were done the break pedal goes to the floor, we were told to change the master cylinder and did,, but it didnt fix the problem,...


After you change brakes you need to bleed air from the brake lines what you need to do is find the bleeder valve its usually rite beside where the brake line goes in the calipers and looks like a grease fitting get someone to pump the brake pedal 3 or 4 times and hold it while someone else loosens the bleeder valve to drain the air out keep the pedal mashed until you get the bleeder valve tightend back up . Do each wheel until fluid comes out check brake fluid while doing this so it doesnt run out. Hope this helps

The chain on the 16 in chain saw keep slipping. Seems the thumb screw will not stay tight? Who can check this and fix?


First thing I would do would be to loosen the thumb screw fully so the chain is as loose as you can get it Next, loosen the chain bar and pull it out as far as possible which will take up the slack in the chain itself. Re tighten the chain bar. Afterward, you can perform detailed adjustment on the chain by playing with the thumb screw.

This solution has always worked for me and my various chainsaws.

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.

Chain keeps coming off Poulan 2150 woodsman gas chainsaw> Common causes?


The most likely cause is a loose chain.
Chain Adjustment
  1. Make sure the chain brake is off (gloves will protest your fingers).
  2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They do not need these really loose - finger tight will do.
  3. Ease the tension adjustment until the chain is obviously loose.
  4. Using one hand, hold the nose of the bar up.
  5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
  6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.

Can not keep chain on bar. Tried 2 different


The inside part of the chain are called drive links. I think when the chains came off the first time (loose chain?) some of these links were slightly deformed (burred). Take a flat file to the burrs on the sides of the drive links. Once repaired keep your chain properly tensioned.

If no burrs please repost. This has piqued my interest. I think a brand new chain will operate correctly.
