lordleonusa Posted January 25, 2008 Share Posted January 25, 2008 I presently have an alloy alternator mounting block on my Vitesse, in the Triumph 2000 Mk.2 shape, replacing that heavy old lump of cast iron. When the weather warms up, I will be replacing it with one of the recently made alloy GT6 style blocks from CC, thereby considerably lowering the alternator, and thereby the centre of gravity. I have one of these alloy blocks after pestering Mr.Pearson, plus one of the GT6 alternator adjustment straps, or links, or whatever they are called. I am rather puzzled at the moment as to which length of fan belt I will need? GCB11125 GT6 to KC7905E GCB11088 GT6 from KC7906E GCB11125 GT6-2 to KC76718 GCB11160 or GCB11162 from KC76719 GCB11150 GT6-3 These are the Unipart numbers that I have listed for the GT6s... Obviously the earlier ones are for Dynamo/Generator equipped cars. Does anyone know the correct number/length of the fan belt as fitted to cars with the Vitesse MK.2/GT6-2 engine fitted with a Lucas Alternator? This would give me a starting point, as the Unipart numbers are not much use in the USA. TIA Léon Link to comment Share on other sites More sharing options...
Nick B. Posted January 25, 2008 Share Posted January 25, 2008 Hi Leon my experience with fan belt are less good. It always turns out that the pulley has been change sometime in the past. I usually take the old belt and go to a local autosupply and asks for a fan belt. In your case -just take a measure - and bring the old belt for reference.

lordleonusa Posted January 25, 2008 Author Share Posted January 25, 2008 Thanks, I suppose my question is more like "how long is a piece of string" It might be that the belt presently on my Vitesse will fit, as I had to change it for a slightly different length when I fitted the Bosch Alternator. I will no doubt find out when I try to fit the new bracket. It does seem odd though that there are so many different belts for the GT6.

DaveNotSoSideways Posted January 25, 2008 Share Posted January 25, 2008 I was always at the local motor-repair shop measuring and borrowing belts Link to comment Share on other sites More sharing options...
Jim Posted January 25, 2008 Share Posted January 25, 2008 Leon, here is how to find out. With the Alternator in a suitable position of adjustment. Place string around the pulleys. You will find the length is in the order of 1.1-1.3 Metres. The exact length is model dependant. But say its 1metre 13 cm, that is 1130mm Knowing that, we look at the belts themselves... The fan belt numbering goes: AAA (Manufacturer bollocks) 1 (belt type, v groove in our case, others included ribbed and toothed - no not condoms!) xxxx (length in millimetres) So for my example car, I'd need AAA11130...geddit? Should help you out a bit... Link to comment Share on other sites More sharing options...
