68vitesse Posted March 23, 2019 Report Share Posted March 23, 2019 Ian your comments made me curious and I found this. https://www.brighthubengineering.com/machine-design/64676-v-belts-types-by-size-classification/ Regards Paul Link to comment Share on other sites More sharing options...
Ian Foster Posted March 25, 2019 Report Share Posted March 25, 2019 Hi Paul That link doesn't seem to show the differences in angle that differentiates a 'V' from a 'wide V'. I found a few sources when I was researching, but not sure I kept anything. Another attached photo showing my current wide V GCB belt alongside the AVX10 and you can see how the edges of the AVX10 have cupped. There's always something ready to trip us up !.

Pete Lewis Posted March 25, 2019 Report Share Posted March 25, 2019 think club shop use the fan belt type and length as shop part numbers FROM THE CATALOGUE cant type all the varieties but as this depends on model year and suchlike the lengths/type/width should if not feint or run upside down are/were printed on your belt.

iana Posted March 31, 2019 Author Report Share Posted March 31, 2019 just looking for a replacement top hose and on ebay there are traders doing a complete set of hoses, the only one i need to replace is the top hose as its damaged - is it worth buying the complete set and keeping the others as spares or will they deteriorate in the store Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 31, 2019 Report Share Posted March 31, 2019 Rimmers and others do just a top hose, eg GRH263 Current orrible rubber doesnt store well even on car the olde ones can be better than replacements of dubious birth ,silicon sets have a lifetime warranty but do cost a lot more ££ If you buy the set store in the dark and cool.

iana Posted March 31, 2019 Author Report Share Posted March 31, 2019 Pete - would this be a better buy then (cant run to silione hoses this year) https://www.ebay.co.uk/itm/TRIUMPH-VITESSE-1600-2000-MK1-MK2-NEW-TOP-RADIATOR-HOSE-GRH263/352463806106?hash=item52107ade9a:g:i4oAAOSwantboAB0&frcectupt=true or this is my other option https://www.ebay.co.uk/itm/NEW-TRIUMPH-VITESSE-1600-2000-TOP-RADIATOR-HOSE-RH622-GRH263-132634/362594201454?hash=item546c4c6f6e:g:Cq0AAOSw2bFcRuTo&frcectupt=true Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 31, 2019 Report Share Posted March 31, 2019 NoS can be better than some modern offerings, but even old rubber has a shelf life The answer is ......down to preference, at least a top hose is an easy change without much coolant losses. nothing lasts for ever , Some say hoses have become a annual service change due to their ability to crack, split, blown , The w pump bypass on my 2000 has lasted 2 years and inards have seperated Pete Link to comment Share on other sites More sharing options...
iana Posted March 31, 2019 Author Report Share Posted March 31, 2019 OK thanks, I guess Ill pick the second one and start saving for a silicone set - hopefully the club will do them on offer! Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 1, 2019 Report Share Posted April 1, 2019 its down to use and expectation you can get 3 nasty sets for the price of a silicon set and if you can find a hose to match these type of suppliers have a wide selection to pick from and lots of other bright ideas to browse https://www.carbuildersolutions.com/uk/ pete Link to comment Share on other sites More sharing options...
iana Posted April 1, 2019 Author Report Share Posted April 1, 2019 right decided to shorten the bracket, is this ok, I could turn the backet to Emile the spacer but the bracket will need further adaption. just need to measure fan belt now and get one. The old belt was a 10A1085, the bit of bracket I chopped off was 45mm to the centre of the bolt hole, so simply do I need a 10A1040? Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 1, 2019 Report Share Posted April 1, 2019 No as the length change to the strap is not proportional to the overall length /diameter of the belt I would suggest if no other way to measure what you need is to simulate the previous position wrap a cord around the pullies and measure its length ,, then get the revised position and repeat , the difference is what you need to change the 1085 too It obviously wont give the belt length but will give the difference Pete 1 Link to comment Share on other sites More sharing options...
68vitesse Posted April 1, 2019 Report Share Posted April 1, 2019 Cut the old belt wrap it around the pulleys, the overlap is the reduction in length. Regards Paul 1 Link to comment Share on other sites More sharing options...

Regards Paul That was my last resort to finding the correct new length fan belt , I'd measured the new length with a piece of electrical flex and came up with 1040mm - I then did as Pete suggested and this indicated a difference of 40mm on the 1085mm belt, so 1045mm .

NonMember Posted April 2, 2019 Report Share Posted April 2, 2019 Small point (or maybe not) but... some of those photos look to me as if the alternator pulley is not in line with the crank and water pump pulleys. You may need to adjust your assorted packing to get them lined up. It makes a fair difference to belt life. Link to comment Share on other sites More sharing options...
