    Got the belt and was looking forward to putting it on my mower but it did not fit which was frustrating, had a look at the reviews and was informed to place the belt in boiling water for 5 mins and it takes two people to fit it. Don't give up as it will fit.

    The part fitted perfectly although the forum advice of soaking it in hot water for 5 minutes really helped. If you are doing this for the first time do remember to fit it to the smaller, grooved drive first then use a smooth tool such as a screwdriver blade to get the last few cms onto the smooth blade drive.

    Received part very quickly. Like other customers have noted though, the belt can be tough to fit. Immersed in boiling water and fitted straight from the bowl is the only way. I am used to mechanical DIY but this will be a fiddle for the less well-trained!. A small instruction leaflet would help. Working very well and as described. Thanks
