Andy Borris Posted December 15, 2011 Share Posted December 15, 2011 What thread is used into the rear trailing arm for the studs, ?ThanksAndy Link to comment Share on other sites More sharing options...
Nick Jones Posted December 15, 2011 Share Posted December 15, 2011 If you mean the ring of studs that hold the back-plate and wheel bearing housing into the trailing arm - 1/4" UNF. Not a great engineering choice!Nick Link to comment Share on other sites More sharing options...
Andy Borris Posted December 15, 2011 Author Share Posted December 15, 2011 Thanks NickGot some new s/h arms on the way and I'd like to clean the threads before fitting, need to check that I've got the right tap!Andy Link to comment Share on other sites More sharing options...
Nick Jones Posted December 15, 2011 Share Posted December 15, 2011 Use Loctite when fitting the studs and note the torque settings on the nuts! It's not high and they do pull out..... as you may well already know! I don't know if the competition boys fit bigger ones - there's not alot of meat there......Nick Link to comment Share on other sites More sharing options...

nang Posted December 16, 2011 Share Posted December 16, 2011 Was about to say the same thing, easier to Helicoil them before you fit them! Link to comment Share on other sites More sharing options...
dazzer Posted December 16, 2011 Share Posted December 16, 2011 I helicoiled the loose ones, same size though and no problems as yet. Have snapped a subframe bush and an arm off during competition in two seperate incidents but the studs continue to hang on in there. Link to comment Share on other sites More sharing options...
Lord Sorbington Posted December 16, 2011 Share Posted December 16, 2011 They seem pretty tough but the correct tightening torque is only about 12ftlb. It's so tempting to tighten them beyond that but then your problems start................. Link to comment Share on other sites More sharing options...

Andy Borris Posted December 16, 2011 Author Share Posted December 16, 2011 Never used Helicoils, but I see that they came in a variety of sizes, would there be any advantage in using a UNC Helicoil in the arms?After all, that's the thread Triumph should have used!Andy Link to comment Share on other sites More sharing options...
Richard B Posted December 16, 2011 Share Posted December 16, 2011 Helicoil it in 5/15UNF and you can continue to use the original studs. Change to UNC and you will need new studs.TBH if helicoiled you should not have a problem in the future with UNF.Kit on eBay costs about £20 - £25. I usually use Re-Coil as Helicoil is a tradename.
