Easy - take off tires, then caps over axle/castle nuts if you have them.
- take cotter pins and axle nuts off both ends of axle. Right side - remove brake drum, then remove two brake shoes, simple Springs connect them, you can pull apart intact, remove any collars, washers off the axle behind brakes, then there might be 4 bolts and a plate - the other side you can see the bearing. Now - this is important - for. The side with the brakes, take a socket bigger than the threads but size of axle lip - and you place that deep socket (side with brakes!) over the threads (threads will be inside deep socket) lip of socket touches lip of axle about 2-3 inches down - hit that w a hammer and the axle will go out to the left if facing rear of four wheeler. Next - remove brake lines and breather hose for rear end.
There are bolts that attach the rear end to the swing arm (to the right) take them out and maybe the bottom guard for rear end. Then where the rear end attaches to drive shaft tube portion of swing arm there are four bolts - when all that is done you'll be able to remove rear end. Undo top bolt or you might get away w/bottom for shock - next two pivot shaft nuts - big socket like, Allen head in middle - remove nut from pivot shaft (left and right side where swing arm pivots) then takeallAllen head and unscrew two thick bolts that the pivot shaft nuts tighten to our - there's a collar and bearing in there where the bike's swing arms pivot at. I've done it a dozen times - if you have any problems or that wasn't too clear, message me, I'll dig up some tech sheets from a service manual I got on a bike that year - close to same model - same mechanics, Yamaha was pretty universal. I got a 98 & 99 Yamaha 2wd and a 96 Yamaha 3504wd. All pretty easy to work on. I have a swing arm I might get rid of from Florida and a decent rate if yours is done for and you gotta replace. I sell and buy off eBay to keep most of my toys on the trail.Good luck

SOURCE: Vt250F Swing arm bearings need replacing

You need to tap the old races out with a large hammer and a drift. A steel chisel works, a punch with a flat end works better. Position the punch or chisel on the visible edge from the opposite side and hit it firmly. Move your device to the opposite edge and hit it again. You don't want to drive only one side out, twisting the race. It needs to be driven fairly evenly, close to straight out. Rarely, you have to cut the race out, if you must do that I would use a rotary tool with a cutting disc.

SOURCE: no front brakes on 95 yamaha big bear atv

gravity bleed. make sure fluid is always full. crack open the bleeder screw and let the brake fluid drip until no bubbles. Then close bleeder top off fluid and replace cap. Now, pull the brake handle. If there is no pressure or has bleed down, the master cylinder is kaput.

Rear wheel removal on yamaha cygnus


Everywhere I read is wrong. For Yamaha Cygnus-X 125cc rear wheel removal
It is removed from the right hand side. Do not start dismantling the gear box side !
Remove 5 bolts of exhaust. Careful don't loose exhaust seal where it connects to engine. You may need friend to lean the bike over to access bolts underneath.
2. Remove main 24mm bolt on axle
No need to loosen brake !
3. Remove 3 bolts holding swing arm. That's the big triangular bit.
4. Pull off the swinging arm and on axle is special shaped washer. Note which way it comes off.
5. Pull off the wheel leaving brake shows behind.

Resr end of bike seems to twitch at times could it be swingarm


Things to check. Is the chain adjusted correctly and is the rear axle tight. With the rear wheel off the ground can the wheel be rocked around on the axle (Are there bad wheel bearings?). If you still have the problem after these checks, raise the rear wheel off the ground,take off the wheel, unbolt the shock (check mounting bolts for looseness), grab the rear swing arm to see if it moves or wiggles at the pivot points. You probably have bad swing arm bearings. If the swing arm bearings are bad you will probably have to change both bearings and the long inner bushing to fix the problem.

How to replace swing arm bearings on 1970 sportster


Get the bike up off the ground and make sure it's secure. Remove the rear wheel and the rear shocks. Look for anything else that may be attached to the swing arm such a brake rod return springs etc.

Once you have everthing off the swing arm, take the pivot bolt out and the swing arm with the bearings slides off the frame. Remvove the screw and lockwasher, bearing lockwasher, the right bearing locknut, and the bearing outer spacer. Using a punch, turn out the left bearing locknut from the fork hub and remove the spacer. From inside the fork, press or drive out the bearings and bearing spacers by applying pressure against the spacer. Press or drive out the bearing shields from fork inner side.

Hope this helps,

Good Luck

Gear shaft


If you are trying to change the boot over the U joint at the swing arm, you don't need to remove any shaft to do that. You do however have to remove the swing arm.
