fayjo56 Posted April 28, 2013 Share Posted April 28, 2013 I need a fan belt for the MW. Is there a 'known' modern equivalent easily available? (I havent tried Bygone Bedford Bits yet). Quote Link to comment Share on other sites More sharing options...
paulbrook Posted April 28, 2013 Share Posted April 28, 2013 The answer is almost certainly yes.... As I recall the normal v belt comes in 4 widths - A, B, C, and Z (dont ask as I have no idea why!!) and the length is measured by the overall outer length. Funnily enough my local agricultural engineer has a wall full of the various sizes. I have pulled belts down off his wall for a 1930s tractor and a Champ amongst others. So I think you will get one no problem. Have a look at http://www.beltingonline.com/vee-and-wedge-belts-213/help-identifying-v-belts-591/?zenid=3i3rg9p4vh8evp6ss7mb8obv94 Cheers!

I have had problems sourcing new belts for wartime Bedford, Austin and Humber especially as the angle of vee and width do not equate to the British Standard A, B, C, etc. There was apparantly, at the time a BS Automotive standard which is no longer recognised. A compromise has to be made and it usually means having to find a belt that rides a little higher in order to get grip on the flanks. Sometimes it is worth looking around autojumbles, if you have a list of numbers from various makers, ie John Bull, Ferodo, etc. Quote Link to comment Share on other sites More sharing options...
rampant rivet Posted April 28, 2013 Share Posted April 28, 2013 Yes I too will be looking for a belt well two really as I'll want a spare if you have any luck give us a nod please :cool2: I have to find a new water pump first as the one fitted to my engine is the wrong type plus it leaks :blush: Quote Link to comment Share on other sites More sharing options...
paulbrook Posted April 28, 2013 Share Posted April 28, 2013 Its well worth having a go with the on line calculator in my post above - it seems to me that a snug if slightly imperfectly fitted new belt might be a better bet than trusting a 40-60 year old one. But like all these things it is up to the individual owner! Quote Link to comment Share on other sites More sharing options...
paulbrook Posted April 28, 2013 Share Posted April 28, 2013 Oh and www.simplybearings.co.uk are pretty good too. Quote Link to comment Share on other sites More sharing options...
AndyB Posted April 29, 2013 Share Posted April 29, 2013 Just looked at the one fitted, it is a Fenner B1080 B41 P13 ? Quote Link to comment Share on other sites More sharing options...
guy66 Posted April 29, 2013 Share Posted April 29, 2013 Hello, I have a industrial belt on my QL and tomorrow will have a look witch size it is. Guy Quote Link to comment Share on other sites More sharing options...
paulbrook Posted April 29, 2013 Share Posted April 29, 2013 Just looked at the one fitted, it is a Fenner B1080 B41 P13 ? so a 41 inch/1080 mm B section... shame that 1080 mm is 42 inches though so not sure why the metric/imperial numbers differ. Still you get the idea.. Quote Link to comment Share on other sites More sharing options...
Chrisg Posted April 29, 2013 Share Posted April 29, 2013 The imperial size is normally the internal measurement and the metric is possibly the pitch length which is about half way around the circumference of the belt. Just to make it more complicated different manufactures have different ways o marking belts Quote Link to comment Share on other sites More sharing options...
paulbrook Posted April 29, 2013 Share Posted April 29, 2013 Well at least we have established that a B41 is a good starter for ten... Quote Link to comment Share on other sites More sharing options...

guy66 Posted May 2, 2013 Share Posted May 2, 2013 Hello, just had a look at the v-belt I fitted on my QL. it is; La 17x1030 it is a bit thigh and think 1040 may be a better choice. Guy Quote Link to comment Share on other sites More sharing options...
fayjo56 Posted May 4, 2013 Author Share Posted May 4, 2013 Hi guys, got my B41, it fits fine but doesnt leave alot for adjustment, so a B40 is probably the way to go. Quote Link to comment Share on other sites More sharing options...
MWMike Posted May 6, 2013 Share Posted May 6, 2013 Try Chris Morter - he has taken over from his dad John, he has sorted my Water pump and i'm sure will have fan belts! Chris Morter - Tel: 01953 602581 Quote Link to comment Share on other sites More sharing options...
