	Dear gurus... Good place to buy polyvee belts and idlers on-line please! Need a new drive belt for the XJ8 and some idlers (A/C delete) Pulleys are 7 rib (7pk) but I don't mind 6 rib given that the A/C is gone now. If I wrap sttring around and play with the tensioner, I get 2170 to 2230 mm lengths. 2200 mm at the centre of travel. Standard sizes: www.clshah.com/cimage10/105707multipullbelts.pdf Do I want to go with a 2170 or a 2205 length? (having measured with string) 2002-2008 Mk5 Fiesta 1.3i with A/C is coming up at a 6PK2170 belt in the Dayco catalogue - sound about right? 7PK2170 seems like an uncommon belt - US only, on the good old CROWN Vic: www.ebay.com/itm/Goodyear-Gatorback-4070855-Belt-7PK2170-HONDA-LINCOLN-FORD-/230678087203?fits=Year:1992\|Make:Ford\|Model:CROWN%20Victoria&hash=item35b57c4623&item=230678087203&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr#ht_500wt_1413 6PK2205 also uncommon, and 7PK2205 is poor quality wobbly children's play pony. Idlers. Jaguar ones are stupid money: www.britishparts.co.uk/.sc/ms/cat/Jaguar%20XJ8%20-%20XJR--Belts-Tensioners Is there a UK equivalent of Rock Auto for these? (20 quid P&P, plus VAT from the US) www.rockauto.com/catalog/moreinfo.php?pk=1390705 www.rockauto.com/catalog/moreinfo.php?pk=2168006

	Halfords - forget searching by car, but you can just search by belt part no FWIW. Only have the 6PK2170 @ 27.67 though! Euro car parts (-25% discounts avail) and GSF both let you search online by belt part number too. Ordered a 6PK2205 Continental belt from Euro Car parts in the end - 2205 mm should be in the middle of the adjustment range and the missing rib shouldn't hurt it without the A/C to drive, will see how close the string gets...

	For measurements, the best way is to get a belt that's too long and then cut it down to fit, then measure it. You might be lucky but the string method can be quite far out, depending on the number of pulleys and whether the belt rides inside or outside each. Google or yellow pages for an industrial belt supplier, they'll have a lot more sizes and are a fraction of the price of motor factors. 7pk is a strange one but you can very easily cut some ribs off an 8 or 10 pk using a stanley knife. I design belt driven compressors as part of my job and trying various belts is the best way to get the right length, particularly if there's not a lot of adjustment and/or a lot of pulleys. For idlers, I'd go to a scrappy with an idea of what you need and find something off the shelf. Or maybe you could find a motor factor with a parts book.

	you will find any place that sell bearings will normally keep belts on the shelf, and a damn sight cheaper too,
