    If  by chance you have an old belt,  if if cracked, take it to a parts supplier,  and they should be able to measure  it on a proper belt checker.   Also, you could cut the belt and measure the extended length.    I think it is a A series belt.

    Hope it helps.  Cheers-Peter.

    The belt that was on it is too big, it doesn’t sit properly in the pulley’s and its too long. I think the previous owner just put on whatever he had lying about. I would just order one from parts but its closed so was going to get one on the net is I had the correct length and width.

    Any help would be appreciated, event the make and model of one on some ones car.

    Try this to get the length.

    How wide is the belt that you emoved?

    If the inside width of the water pump pulley at the top is 1/2 inch, it should be a A belt.   If 5/8″, could be called a B series.  One chap here said it should be an A, and another thought perhaps a B33.

    To check the length,  slacken the generator to the closed position, then if you have  some thin, but strong cardboard,  cut a piece around 1 inch wide,  with the help of another pair of hands, please the strio on the top of the water pump pulley, then around the  generator, then down and around the crank and back to the top, and mark the length. Then measure the length.

    If it is an A belt, subtract 2 inches, and that shoud be the length. If it is 5/8, I think you need to subtrack 3 inches.

    Talk to your friendly local parts shop, and ask if you can return the belt if it is damaged should the length not be correct.

    Happy Austineering-Peter

    Hi Dave,

    The correct A40 Devon fan belts are available through Longbridge Motor Spares the new spares supplier for the club.
