Your local motorfactors should have them in stock or get one within a day or so.
I'd expect you to have some of the big factors around your nearest city. Google it and you should have a few crop up.

Black Jimny's don't get stuck!

Thankyou

On my twin cam the power steering belt has to come off first: there is a pin inside a quadrant on the tensioner pulley that undoes and the pulley pivots. To get the tension back you need to fit a hex key into a hole in the adjuster and apply tension whilst tightening the bolt. (This is a minor miracle if you can do it)

To change the actual fan belt you need to undo the pivot bolt at the bottom of the alternator. If it wont come undone you will have to use huge tyre levers to force the alternator round, or spend a day taking out the radiator and stripping the engine to get the alternator brackets off the engine like I did :(

Here is the power steering tensioner on a twin cam, don't know what is on a single cam I'm afraid.
(If this is noisy like mine, a new one is £140 :woohoo: :woohoo: :woohoo: )


If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)

The one at the bottom of the alternator with a head made of plasticene that now has a round hole in it, but should be a hexagon key?

I had to take out the radiator to get tools to it, but it wouldn't move for anything, so I took the brackets off the engine,(I took the drivers side engine mount off too), but this might have been to get the rusty water pipe off that I sorted at the same time..
You might get the alternator brackets off with the radiator still in.
The other end of the bolt goes through a welded on nut in the rear bracket, pity, as you can just about get to it, if it were a nut you could undo it.

Try removing the top adjustment bolt and forcing the alternator round, be careful what you lever against so you don't break anything.

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)

Right managed to get the alternator belt on.

What I did was spray the pivot bolt with WD40 leave to soak in,then I loosened the top two off. After that I put the belt on and got a tyre lever or an iron bar to pull the alternator over and tighten the belt to the required amount, while I held the alternator in place I tightened up the top two nuts.

Now I had to take the power steering belt off to get the other belt on, so got that off ok by unscrewing the power steering pump off, this gave it just enough to take it off, but the problem I found was that putting it back on was hard, if i put the belt on first the bolts wont go back in, if i put the bolts in first the belt wont go back on. I managed to find a way round this by Jacking up the front left tyre side putting the tyre lever i had between the bottom of the pump and the ground and turning the jack slowly to the required height, using the weight of the car to do that work. Tightened up the nuts and job done.

It was awkward as I didnt take out the radiator so shaved of a couple of layers of skin on my knuckles doing it.

Feeling chuffed as I did this all myself and next year planning to put new suspension new AT tyres on it etc.

Thnaks for your help people.
