rulloyd Posted November 9, 2020 Report Share Posted November 9, 2020 When fitting the alternator on my gt6 I have found it fouls the new engine valance panels bought from the club shop. đ©đ©Shortening the fan belt is not an option as the alternator is prevented from recoiling very far thanks to the cast mounting bracket being in the way.   The GT6 bracket is quite long and lowers the alternator -I have no idea why.  But I see the TR6 mounting bracket appears to be quite a bit different and may sort out my problem.  Any ideas why and any reason I shouldnât use the tr6 bracket instead? couple of links showing the difference below: https://www.ebay.co.uk/itm/Triumph-TR6-Spitfire-light-weight-alternator-bracket/254672161711?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D56f7cca2d37e49b2ab642fc6d3e29ec5%26pid%3D100675%26rk%3D1%26rkt%3D15%26mehot%3Dnone%26sd%3D254672161711%26itm%3D254672161711%26pmt%3D0%26noa%3D1%26pg%3D2380057%26brand%3DTriumph&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3Ab65c3ea7-2218-11eb-8b8b-820f3ba11088%7Cparentrq%3Aaa2764e51750ad331bbb238bffe61298%7Ciid%3A1  https://www.ebay.co.uk/itm/Triumph-GT6-light-weight-alternator-bracket/254678919493?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D56f7cca2d37e49b2ab642fc6d3e29ec5%26pid%3D100675%26rk%3D3%26rkt%3D15%26mehot%3Dnone%26sd%3D254672161711%26itm%3D254678919493%26pmt%3D0%26noa%3D1%26pg%3D2380057%26brand%3DTriumph&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3Ab65c3ea7-2218-11eb-8b8b-820f3ba11088%7Cparentrq%3Aaa2764e51750ad331bbb238bffe61298%7Ciid%3A1  Any advice much appreciated.  Rich Link to comment Share on other sites More sharing options...
rulloyd Posted November 9, 2020 Author Report Share Posted November 9, 2020 Incidentally, the TR6 mounting is advertised for the Spitfire also. Â Is this right? Rich Link to comment Share on other sites More sharing options...
NonMember Posted November 9, 2020 Report Share Posted November 9, 2020 The alternator mounting bracket on nearly all small Triumph engines is the same, whether it be Spitfire, Toledo, 2000 or TR. The GT6 is the exception because fitting the alternator on the normal bracket would foul the bonnet. Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 9, 2020 Report Share Posted November 9, 2020 just what alternator are you fitting as the various makes have variation in their lower mounts pete  Link to comment Share on other sites More sharing options...
Colin Lindsay Posted November 9, 2020 Report Share Posted November 9, 2020 The side valences are probably made to the original spec which was for dynamo, which sits higher than the alternator. (It's possible the alternator is fitted lower so as not to foul the bonnet when it's closed, being bigger and broader than the dynamo.) When I bought my valences I had to modify the top of the passenger side to allow the alternator to sit on the correct brackets, ands this little cut-out allows for quite a bit of adjustment on the belt.  Link to comment Share on other sites More sharing options...

rulloyd Posted November 9, 2020 Author Report Share Posted November 9, 2020 5 hours ago, Pete Lewis said: just what alternator are you fitting as the various makes have variation in their lower mounts pete  The standard GT6 alternator what ever that is. Like Colin, I think Iâll have to modify the valance which is quite annoying as these are the new ones the club shop have recently had manufactured and they are powder coated.  Grrrr. incidentally, the ânewâ fan vowel will also have to be modified as there is no way it will join the side valances without pressing hard against the rad at the top - which canât be right. I did mention all these problems to Angie but she said that no one else has fed back đ©đ©đ© Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 9, 2020 Report Share Posted November 9, 2020 so i hazard a guess its a lucas A127 or similar the only thing to keep an eye on is the tail mount this has a tight fitting tube /bush inserted. it is very important the lug is equally spaced with bush showing each side or the lug this is due to wild case expansion due to heat , if the lug is all one end it will very soon break it off im sure Doug did a bit of faf and fettling on some side shields Pete Link to comment Share on other sites More sharing options...
Gully Posted November 9, 2020 Report Share Posted November 9, 2020 The original fitment alternator was the Lucas ACR 15 according to the parts book. Interestingly, the parts book also shows the valances without any cut outs, which is endorsed by image 8.22 in John Thomason's Guide to Originality, so something is wrong with the replacement parts.

Is that bush supplied and fitted with the alternator. Dave Edited November 9, 2020 by daverclasper Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 9, 2020 Report Share Posted November 9, 2020 YES its part of the unit ,if it needs one it will have one , eg, with no tube/bush the hole will be far too large not a good pic but this shows the type of rear sliding bush in the rear lug the lug needs to be central on the bush pete Link to comment Share on other sites More sharing options...

Gully It's probable that the valences are fine, photo on left below (mine were altered to take an oil cooler and a non-standard alternator originally, and the currently fitted version is a 55amp uprated replacement ) and it's the bracket that Rich is using that's the problem, especially if it differs from the others he's looked at - it may be lowering the alternator a shade too far. It's interesting however that the photo of the aftermarket alloy versions to the right below also shows the top edge cut out for the alternator, although not as drastically as mine. Space is at a premium and the slightest deviation may cause fitting problems.    1 Link to comment Share on other sites More sharing options...

I should think the mount is right as thereâs only 2 choices right? I see that all GT6 use the same one. All GT6:  214268 (alternator) everything else: 147899 (alternator) incidentally, where do the valances connect to at the top front if you donât have the radiator cowl like the yellow GT6 pictured? thanks for all the input Rich Link to comment Share on other sites More sharing options...
