Hi there,

put your bicyles on upside down position,wheel should on top so you can work freelywork on ,then rotate the pedal to check what the problem it should be freely rotating,check break pads if it was engage even w/o pressing control.release brake cable wire to loosen.if not in the break,check the sprocket gear if connecting to the chain belt,check your sprocket release lock,if damage replace sprocket, check the bearing of the two wheel center shafting if worn out replace bearing,on front wheel there are two quick release nuts,loosen and pull out wheel and loosen all nuts and lock plate bearing,pull out shafting with the bearing,examine mostly bearing worn out also shafting in some occasion its worn out also,possible if you want replace one set center shafting and bearing ts not costly,on rear wheel with sprocket it different to disconnect,beacause there is sprocket,you should dismantle the locked plate and lock nuts of sprocket before the shafting assymble same procedure now on front wheel when after disconnecting sprocket on rear wheel.hope this will guide you and solved your problem have anice day.

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....

The chain doesn't move when the pedals are turned


Take you calibrated eyeball and evaluate what DOES move or what components of the bike may be preventing it (like brakes). Elevate the rear wheel so it CAN turn and rotate the pedals. I assume the pedals turn because you say they do. Is the chain even engaged on the chainring?

Does a 2020 JD gas have a differential lock


Some had this option. If yours does it will have a pedal on the left side foot plate toward the rear end. If the pedal has been removed the shaft should still be there sticking out of the transmission housing behind the PTO engage lever.You have to hold the foot pedal down to keep it engaged. Sometimes when you release it will stay there until you take pressure off the locking mechanism by turning the steering wheel one way or the other while the tractor is moving.

Diamondback Outlook - When pedaling the rear sprocket is turning without engaging the wheel/axle


Sounds like the pawls inside the cassette body have stripped out. You need a new wheel or take it to BIke Shop for evaluation and repair depending on cost.

Pedals spin wheel doesn't turn


Bottom brackets just connect the cranks to the bike and keep the drivetrain aligned while you wail on the pedals.

I assume you mean the rear wheel spins freely when you pedal after a coast or stop. That would be the pawls in the rear cassette, freewheel or axle failing to engage. When you coast, the whirring, clicking sound you would hear is the pawls gliding over the detents. When you apply forward torque, they drop into the detents and provide drive. Like a ratchet.

Have a shop look at it. Don't ride the bike if it's going to do that. You may stand up and stomp on the pedals and have it let go and wake up with a broken jaw because you went over the handlebars, if you survive being run over. The rear wheel and drive components are not beginner bike mechanics.

You don't say what kind of drive it is.

Rear wheels-


Both wheels should spin in 2nd gear. Only one wheel may spin in 1st, but if you put a little pressure on the one wheel that spins it should make the other wheel start spinning.
But both wheels should spin in high gear at the same time.
Hope this helps. If there is more help you can also ask these guys at this website. http://www.shopjandl.com/ I get my parts from them and they seem to also work on them as well
