My fan belt got a bit mangled so I immediately went down to the cornershop motor factors.... Didn't have one in so I ordered one up (as a spare!)

Went down to the slightly more warehouse spares place, they have one suitable for a 2cv... something called a 'Gates 6210MC'... but... even with the alternator pushed down as far as it will go, it's still about a belts width to small to go on... I swapped it for the next size up (Gates) which fitted fine! :roll: (there is also scope to move the alternator up to take the slack off slightly larger belts as well surely?)

Well! I got my 'cornershop' belt today and it's another 'Gates 6210MC' :shock: :roll:

Gates 6210MC AVX10 x 750la (if that means summat to sum one!) is not quite right if you want to stick that in your xml database! :ugeek:

You dont have one of the last rubber pulley fans do you? you need the bigger belt

i used to know what size it was off by heart but now i have to write stuff down.




then spend days trying to find "that" bit of paper :?

No it's a metal one.... Haven't had this problem with other off the shelf belts!

I just think there is a too small one in the 'system', Having just read off other manufacturer's lists! :?

I'd heard that cars built in the last year or two, ('89, '90), used a different sized(bigger?) belt because one of the pulleys was different. And have in the past been sold a belt that was slightly too small. However my car's an '88 and both pulleys look normal.

Does any one have a picture, or accurate description, of a late type, bigger pulley, so that my vague idea could become a bit of definite knowledge.

Joolz,
the rubber mounted pulleys are very easy to spot.
My guess is that Citroen had finally acknowledged there was a problem with the 'spun' fan pulleys and decided to isolate the metal part of the pulley from high speed vibration of the crankshaft.

ken

I bid 763mm for belt length to suit those pulleys.

p.s. @ imo,
You don't happen to have a replacement Iskra type alternator fitted, by any chance?
On some of those, the driven pulley diameter is larger than on the original versions.
