Riding yesterday and clutch cable went, felt like a rubber band breaking. Had a look today, not broken at either end. Can I fix this myself?

The clutch cable would be the first thing to look at in this case. Check the cable to see if you can see a break, it is usually at one of the ends, very seldom in the middle. If the cable is not broken then something in the clutch assembly could have collapsed, but the cable is the easiest to look at first.

Well, you only need the clutch to release, and that cannot be major. Inspect the cable completely, does it move at the trans end when you pulll it. What is inside is essentially a fork on a release bearing, a rod, and the clutch spring plate.

They dont often just come loose, you will most likely need a new cable

FIRST THERE ISNT A SPEEDOCABLE. SOUNDS LIKE THE VSS(VEHICLE SPEEED SENSOR ) WIRING IS DAMAGED OR THE SENSOR WENT BAD. THE COMPUTER USES THIS AS A REFERENCE SIGNAL TO KNOW WHEN THE TRANSMISSION SHOULD SHIFT.

There are four possibilities. From worst to easiest to fix: (don't worry, a link provided below has diagrams of all the parts in exploded view with part names)

1. There are two springs holding the brake shoes firmly against pivot post and brake lever cam, the ends of these can wear through and break. These provide most of the spring tension felt in a cable operated expanding shoe brake. Requires wheel removal and simple removal of brake hub to access.

2. The cam that expands the shoes (when rear lever is actuated) runs through a waterproofing rubber grommet. This grommet can often tear and bind up, reducing the return spring's effectiveness.

3. There is a spring behind the brake's foot pedal frame mount and the plate that pulls the front of the cable end. This maybe either dislodged or the angled ends broken off.

There is a compression spring at rear wheel end of cable, between cable stop and lever arm. This can be removed, stretched and replaced or packed with spacers to provide additional spring.

Check site below: Wheels/tyres/drive - Rear wheel parts #6 (shoe springs) part #7 (brake cam)
Frame/Footrests - part #4 (pedal return spring) part #9 (compression spring)

If this helps let me know below, ...Cheers.

Since it happened suddenly, the problem is probably in the cable. Look at the end of the cable where it connects to the clutch arm. Pull the lever. Does the arm move? If not, replace the cable. Check also that the spring is not broken. If the arm does move as it should then the shaft the arm connects to may be broken.

sounds like a selecter fork broke or dislodge

You blew the clutch cylinder or the related slave cylinder.  Refill with brake fluid and check for leaks and remember to bleed out the air.

I had the same problem. To remove the rubber band, I had to remove a plastic housing that keeps the band in place. It's a bit difficult, but I managed to without breaking anything with two small flat point screwdrivers. I couldn't find any original replacement part, so I looked for something similar in the market. The rubber has to be really soft to pick up the paper, also a reason why it cracks a lot. If the rubber is flat, then try to use fine sandpaper on it to give it some texture. clean it well, so it won't mess up the paper. Put the rubber band on the housing and clip it on. This should end with all the paper jams and weird noises. The job is easier done, if you remove the housing of the printer (six screws). Never use brute force. If it doesn't come out, there's something that you're doing wrong. Be patient, so you won't break anything. Good luck!

Generic problem for all Vacuums
The rubber band that turns

The rubber band that turns the roller on the vacuum keeps breaking. I just bought a new rubber band, put it on, and it broke immediately. Can it be fixed?

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
I see there could be 2 problems – either your revolving brush has hair or thread buildup in the ends of the brushroll of which is causing the belt to break and would need to be cleaned out, or check the bearings on each end – they could be **** as well, or the motor shaft or motor assm is not tuning freely and in that case the motor should be replaced and it is not the belt – one other thing is to make sure the motor is in there securely. Once you get the belt on then roll the pulley and the belt together to make sure the belt is on correctly if the brushroll spins freely.
