See links below. Best to study written instructions first, then look at YouTube videos to see the procedure (just Google what you want to see, such as adjust front derailleur, and click on "Videos." Many videos are inaccurate or leave out steps, so I do not recommend going only by them. Even better, if you have a bike co-op nearby, or a bike shop that has repair clinics/classes then try that out. In-person assistance is always best.

Since you didn't specify which derailleur needed adjusting, I have included links to adjusting both the front and rear derailleurs.

I have a Kawasaki kx20s 10 speed boys mountain bike that needs the rear brake cable replaced and both the front and rear derailer gear cables adjusted or possibly replaced. Is there a manual or diagram of...

1st The brakes: Once you have ran the cable through appropriate cable holders and to the brakes-you hold the brake calipers shut-remove excess slack from cable by pulling on it with pliers and back off a little before tightening the nut holding the cable(amount you have to back off tension depends on how strait your wheel is).
The Front Derailer doesn't usually have adjustment so you put the gear lever in top gear-loosen the nut holding the cable-push the derailer into the right position-remove slack from cable with pliers then tighten the nut.
The Rear Derailer: will need to be done the same way if your running a new cable..*But there is a screw on the derailer near the junction of the 2 parts that adjusts the position of the derailer- so you can do minor adjustments-**NOTE-there are 2 screws- 1 changes the position in or out and the other changes the angle**

I have a SRAM 3.0 rear derailer. It is difficult going into the two largest gears, I have a 7 speed cassette. I notice there is no barrel adjustment on it. Any suggestions

The barrel is for fine tuning the indexing among the gears. Limit screws set the inner and outer physical swing of the derailleur.

A simple web search for "Sram 3.0 Mountain Bike Rear Derailleur adjustment" finds the manual.

There IS a barrel adjuster.

Hufyy 26" Tundra 18 speed bike....GEars are clicking

Sounds like the rear derailer needs adjustment. Are you handy with tools? There should be a micro adjuster on the cable for the rear derailer. It might be located at the shifter on the handle bars, or at the rear derailur. Follow the cable from shifter to derailer, Look for an adjusting nut, when you find it, turn it counter clockwise to remove slack from the line. Go one turn at a time, ride it and shift through the gears. Repeat until the noise stops or you run out of adjustment. If that doesn't fix it, you need to srew the adjuster all the way back in, shift it to the highest gear, loosen the bolt the holds the cable on the derailer and pull the cable tight and tighten the bolt back down. If you are unsure about doing this, go to your local bike shop and have them fix it AND show you how to do it.

Adjusting front derailer

Typically adjusting the front derailleur is a matter of adjusting the two adjusting screws on the derailleur. So turn the bike upside down. It should sit on its seat and handle bars. Find the two adjusting screws one will prevent the derailleur from traveling too far out preventing the chain from coming off. The other screw prevents the derailleur from traveling too far in keeping the chain from falling off that way. Now once you have found the screws slowly start turning the pedals like it was being ridden. Move the derailleur out as far as it will go if you see the chain is about to come off adjust the screw. Do same for inside screw. Now move the back derailleur all the way in and retest front derailleur, repeater with rear derailleur all the was out. Hope that helps. Oh, the back derailleur adjusts same way.
