Your best bet, if you don't have a camera, is to take it to your local bike expert or mechanic and ask them to point out the limit screws for you. Otherwise, take a few pictures of the RD and post them, I'll take a look and see if I can point them out for you.

I have a honda trx 350 es my problem is it wont go into any gear the motor was clicking but now its gone dead


Hello,

Have a helper lift the rear wheel of the bicycle slightly off the ground.

2
Kneel beside the bike and turn the pedals slowly by hand. Using the shift lever, adjust the front derailleur so that it rests at about the midpoint of its movement range.

3
If the initial problem is that the chain won't shift onto the largest rear gear, locate the two small side-by-side adjustment screws on the rear derailleur. Turn the left (or upper) adjustment screw counterclockwise a quarter turn with a small Phillips screwdriver. If the initial problem is that the chain won't shift onto the smallest rear gear, skip to step 6.

4
Continue turning the pedals and shift through all the rear gears. If the chain will still not go onto the largest rear gear, shift the chain back down to the smallest rear gear. Turn the right (or lower) adjustment screw clockwise as far as possible before the chain begins to click or rattle.

5
Shift through the gears again to test. If necessary, turn the left (or upper) screw counterclockwise another quarter turn.

6
If the initial problem is that the chain won't shift onto the smallest rear gear, begin by turning the right (or lower) adjustment screw counterclockwise a quarter turn. Shift through the gears to test.

7
If the chain still won't go onto the smallest rear gear, shift the chain to the largest rear gear. Turn the left (or upper) adjustment screw clockwise as far as possible before the chain begins to click or rattle. Shift through all the gears to test.

8
Follow steps 1 through 7 for the front derailleur, which operates on exactly the same mechanism as the rear derailleur (you still lift the rear wheel in step 1). There are two side-by-side adjusting screws that control alignment.
If otherwise,
Tighten the high gear screw, the one that hits a cam when you shift to the smallest sprocket, until you can no longer shift into high gear. Put the shifter in high gear position and while turning the pedals, unscrew the high gear screw until the system engages high gear again. Shift between high gear and the second smallest several times, backing the screw out a little more, just until the derailleur shifts smoothly.

2. Tighten the low gear screw until you no longer get first gear. Repeat the process for this low gear limit - back the screw out just until the bike shifts smoothly from the second largest to the largest sprocket.

3. If you cannot engage high or low gear, or if the above technique does not work for high or low gear, the cable may be improperly adjusted.
Shift into high gear and push the shifter all the way to the end of its travel. Loosen the cable inner wire anchor bolt. That's the bolt with a hole through which the derailleur control wire is clamped. Pull the slack out of the wire, and retighten the anchor bolt.

If your bike has index shifting, you'll find an adjusting barrel either at the derailleur or the shifter. The adjusting barrel is a hollow screw at which the cable outer housing stops, but which the inner wire continues through. Fine adjust the cable tension by turning the adjusting barrel until the clicks on the shifter correspond with proper shifting at the derailleur.

If your bicycle does not engage high gear, or is slow to engage high gear, even though properly adjusted, the cable is probably the culprit. Replace the sticky or rusted cable, and the problem will usually go away.

If you have done everything right, but the bicycle does not shift reliably, the most common reason is that the chain and freewheel are too worn to work properly. If you replace one, you must replace both. A new chain on an old freewheel or visa versa usually skips, and the new part wears out very quickly.

Another possibility is a bent derailleur. The guide pulleys, those little wheels that take up the chain slack, must pivot on the same plane as the freewheel sprockets. Derailleurs become bent when the bike falls over on the right-hand side. Whenever you set a bicycle down, or put it in a car, set it on its left side to protect the derailleur. You can sometimes straighten out a bent derailleur by simply bending it back and readjusting the limit screws.


Hoping this will help to solve the problem, do take care....

As I shift the large gears I can't get into the mountain gear , it needs some adjustments and I don't know just how to do that. Chris


both the foot and wheel gear have two adj screws. turn bic upside down put gear in lowest setting turn wheel with foot peddle.adj front gear so outside gear or the side on the frame is bar-ly going to touch lever.do the same with rear wheel then move level to highest setting.and do the same this time the out side should bar-ly be touching the chain.after a few adj the gear should shift without any binning.

Cannot get rear derailer to work properly 24 inch girls evolution


Don't start messing with the derailleur yet! Make sure your shifting trouble isn't due to something else, such as a warped, dirty, or stretched chain, gummed-up pulleys, crud in the cable housing, trapped cable, or a bent derailleur hanger
Clean the chain and the rear derailleur pulleys. Pull the chain away from each pulley, and turn the pulley to make sure it can move freely. A pulley that offers resistance to turning must be replaced.
Now check the cable to be sure it slides freely. Mud and grit within the cable housing, or on a cable-guide, can keep the derailleur from moving a "full gear" during downshifts. If the cable doesn't slide freely in the housing, you may be able to clean or lube it to restore smooth shifting.
Let the high-gear limit screw. In your highest gear on the shifter, and with the chain on the smallest cog, position the derailleur so the upper pulley exactly matches the teeth of the small cog. Run the chain a bit with the front derailleur in the large ring, adjusting the limit screw until the pulley and the cog seem to match perfectly.

Setting the high-gear (small cog) limiting screw.



Once you're sure the derailleur matches the cog, move it just a whisker (1/8 to 1/4 turn) towards the other cogs. (You may need to readjust a bit if you get chain-skip.)

Closeup of setting the limiting screw.



Now adjust the low-gear limit screw. Shift into the lowest gear (largest cog). If it won't go, loosen the limit screw. With the chain on the largest cog (and the front derailleur in the small chainring), adjust the derailleur so the upper pulley exactly matches the teeth of the large cog.Once it's perfect, turn the limit screw so it moves the derailleur a tiny amount towards the other cogs (1/8 to 1/4 turn usually works).

Setting the low-gear (largest cog) limiting screw.



Now shift to the highest gear (smallest cog). Push the shift lever to downshift one gear (go from the smallest cog to the next-smallest). If it doesn't shift, tighten the cable with the barrel adjuster, 1/2 turn counter-clockwise. Backshift and try again. Continue tightening until it shifts. If it overshifts, going from the smallest cog to the third-smallest, loosen the cable by turning 1/2 turn clockwise. Backshift and repeat until it shifts exactly from the small to the next-smallest cog.

Fine adjustment of tension in the derailleur cable.





Now go to the second-smallest ring. Tighten or loosen the cable slightly, until the outer side plates of the chain are just clearing the third-smallest cog. Shift up and down, fine-tuning until you're satisfied.

Checking the position of the chain on the cogs.

My Shimano TX-31 is not lined up correctly. When I shift into 7th the chain comes off because the Derailer goes beyond the 7 sprocket. How do I adjust this? It is also causes a clicking sound when in 1...


There are two screws that limit how far the derailer travels in both directions. Yours is apparently traveling to far out, and not far enough in. See the diagram at the link below. The two screws are identified by number 3. You will need to adjust both of them. With the chain on an intermediate gear, try turning one of them them 1/4 turn, then check the result. You'll soon get it right. Good luck. If you found this useful, please vote

Wont change gears 12or3


There should be one or two limiting screws for the front derailleur that you can use to adjust how far out/in the derailleur moves to shift the chain over. You can ask a friend to lift the back end of the bike off the ground while you do the adjusting of these screws and then try shifting the gear while moving the peddles with your other hand.

I have a 1998 Gt Aggressor 26" bicycle. When shifting in the large gears, it hesitates before shifting or does not shift at all and just clicks. Can you help?


sound like the shift adjustment need moving or the cable to be adjusted from gear shift to the cogs there are a couple of ways to do this first select the low gear so the cable is slack and then look where the cable connects to the cog shift if you loosen the nust holding the cable and pull a little cable through retighten and try shifting.. if this doesnt work look at the way the guide moves the chain across if you see the guide stopping before the chain goes onto the cog look closely and you will see two small screws on the arm one is to stop the guide going to far to the right and one to the left look at the one on the right that shlould be the one for the transit to the large gear cog if you undo the screw half a turn then try the gear shift again see of it move far enough to put the chanin on the cog if not undo a little more.. these screws work for both the small and large cog shifting so the same can be done for the small cog if the chain keeps coming off.. Good Luck A

Shimano 105. Front derailleur won't shift down


It sounds like you could have two different problems. Your derailleur has become contaminated or your shifter may need to be lubed. Either way, the likely solution is the same. The best solution to get the derailleur operating again is to spray it with GT-85 or PB blaster and manually move in back and furth until it is working again. The same goes for the 105 shifter, spray GT-85 inside the shifter by compressing the brake lever and spraying towards the head of the shift cable. This will solve a non-functioning shifter many times.

The only other problem that fits is the limit screws could be wrong or the deraileur is in the wrong position. This would not be the case unless someone adjusted your derailleur before the ride you started have that problem. Or if the derailleur has moved. Both of which require the derailleur to be fully readjusted.

Hope this helps. Thank you

Clucth not disengauging....


try this.you have 2 shifter cables.one is select cable the other is shift cable.first put the transmission selector lever in neutral.then move transmission shift lever to 4th gear.depress clutch to if necessary to shift.move the shift lever to the 4th gear position until contacts stop.then you turn the adjuster turn buckle so the shift cable eye aligns with the eye in the gear shift lever.when installing the cable eye. make sure the flange side of plastic bushing at the shift cable end is on the cotter pin side.the cables should be adjusted so the clearance between the shift lever and both stoppers are equal when the shift lever is moved to 3rd and 4th gear. move the shift lever to each position and check that the shifting is smooth.

Changing gears


goes into gear fine. Your boot is most likely preventing the lever from returning to zero. Then when you try to change this will happen. You need to either adjust your lever postion (1 set screw) or remove the bulky rubber foot pads. I have large feet, so removing the rubber pads was almost a necessity. Before doing that, I had to shift up with the little 1/4 bit of sole that stick out from the sides of your boot (if you have cheap boots like me!). ,,,
