'twas the shine that caught me, too... plus the ease of adjustment. No more loosening the bolt that goes through the waterpump housing and getting water leaks...

Ian The clip is just a folded strip of thin stainless steel offcut, used the same material for alternator fan shroud and for the fuel pipe clip fixed by one of the water pump housing bolts.

However, a rigging screw/turnbuckle will be A4 stainless and not A2 because of the salt water immersion, and a failure potentially means the mast coming down rather than the fan belt coming loose.

Iain T Posted June 7, 2020 Report Share Posted June 7, 2020 +1 for Colin's solution it looks good and I need some s/s bling on my black engine! I take it you just cut off one of the legs of the end U bracket? Link to comment Share on other sites More sharing options...

I take it you just cut off one of the legs of the end U bracket? Yep; measure the length so as to order the correct size of the one you want, then one of the end clips requires trimmed at one side. This kind gent has saved me a lot of typing: https://myquickfix.co.uk/2016/07/10/gt6-spitfire-diy-alternator-bracket-improvement/ This one is only £4.99 and in the right length: https://www.gsproducts.co.uk/8mm-stainless-steel-rigging-screw-jaw-jaw/ Link to comment Share on other sites More sharing options...

JohnD Posted June 7, 2020 Report Share Posted June 7, 2020 No, Colin, not if the clevis is in front of the alternator and you have lined that up, using shims or whatever. Look at your own pic and imagine that. PS why the fibre washers under the locknuts? They'll work loose. Link to comment Share on other sites More sharing options...

No idea, they were there when I bought it... that photo was taken in 2010 and it hasn't dropped off yet! (It does get adjusted regularly at fanbelt changes etc.. maybe next time I'll remove them...)

JohnD Posted June 8, 2020 Report Share Posted June 8, 2020 You made me think again! This part is stainless and stainless is prone to seizing, as small areas cold-weld together. If the lock-nut is forced against the barrel, could the washer be to protect it from seizing? But no! Cold-welding is the result of micromovement and localised heating. A washer may prevent contact between the nut and the barrel, but allow more movement at the threads, which when the nut is locked are forced together, and may cold-weld and seize, like this: The engine bay is as hostile an environment as the sea, which rigging screws are designed for. Heat is said to be a factor in inducing cold-welding! Antiseize lubricants are recommended, so Hypoid gear oil??? But I think I will use copper grease on the threads, and leave the nut-to-barrel interface naked. Thanks, Colin, for making me think and research!

Iain T Posted June 8, 2020 Report Share Posted June 8, 2020 Ooooh this is getting much too technical when a simple bracket will suffice? If you need an offset then 68vitesse's gets my vote. Link to comment Share on other sites More sharing options...

Iain T Posted June 9, 2020 Report Share Posted June 9, 2020 Colin, I'm with you there we all need more fun🤡 in these trying times the Jokes section has kept my spirits up🥃 If you want a turnbuckle (they do look good) why not rose jointed ends to take up any offset? If they are good enough for track rod ends they must be good enough for adjusting a fan belt tension. I'm off to do some general car twiddling so I'll investigate!

JohnD Posted June 9, 2020 Report Share Posted June 9, 2020 36 minutes ago, Pete Lewis said: but a rose joint does not aid support like a strap might Pete Eh? Please explain, Pete. Colin's attachment to the alternator is in double shear, very secure, when a joint would has to be in single. That your meaning? Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 9, 2020 Report Share Posted June 9, 2020 I thought a rose joint allows swivel a strap is fixed the alternator is supported by 3 lugs if its a A127 type design some euro have a solid full length lower boss , so more supported/ stable just a thought Pete Link to comment Share on other sites More sharing options...
Gully Posted November 4, 2020 Report Share Posted November 4, 2020 The alternator bracket on my GT6 has been a bit of a bodge for a while. Looking at the parts book, it wasn't an original one and the forked section has always seemed a little short. When I changed my alternator a few years ago for one of the same type and pulley size, at the most extended position the fan belt was a little too loose, so I bolted a wishbone shim to the end of the bracket to extend the adjustment fork. It's worked fine for 2-3 years, but has never been a particularly elegant solution, so at the weekend I installed a shiny, rose-jointed one purchased from eBay. Really pleased with it and yes, I did use lots of copper slip 😀 Gully Link to comment Share on other sites More sharing options...
