I need to change the supercharger belt on my S type R but do not want to fit the modified kit, does anyone know where I can get an original type belt ?
Thanks
Tony

You may well need to go to a Jaguar Main Dealer for this part. I suspect you have the smooth sided belt with ribs on the reverse side. Such belts are somewhat difficult to source on the internet.

The modification kit is best fitted where higher charger speeds and load together with small pulleys are fitted. This includes a an idler pulley with ribs and shoulders, a 0.8mm shortened mounting bracket, a stronger automatic tensioner and a double sided ribbed belt. The kit was redesigned to reduce chirping noise from the belt when cold and in some cases was fitted to combat belt flinging which could occasionally occur with the original smooth back belt and idler pulley distinguishable by having rounded shoulders and rib-less idler pulley running surface.

The early automatic tensioner can become weak given high mileage. The spring if tired can cause the tensioner arm to oscillate which leads to lack of belt tension. In such instances, the later kit should be fitted which includes all necessary parts. I recall I paid around £273 inc VAT which solved my belt throwing antics at a stroke.

Hope that helps.

Goodyear used to make replacement called a gatorbelt, but unsure if still available? Worth a bit of searching?

I might have got one !!!
When it arrives from the USA we shall see.
Will keep you all posted

Powerhouse used to sell these but they don't seem to list them anymore, let us know how you got on Tony.
