WeeGee Posted April 20, 2007 Report Share Posted April 20, 2007 (edited) Just got a pair of Middleburns and a Gigapipe BB (Splined), i'm installing it using a bit of copper grease on the splines and bolt thread! problem is it doesn't want to butt up against the BB "backing flange". Is it usual to see about 1mm of spline between the crank and the BB or should it do up tight against the BF??

tom 20 Posted April 20, 2007 Report Share Posted April 20, 2007 I didn't bother putting grease on mine (echo forged), i put them on as i got them. They seem to be fine, they did come loose a couple of times on the first few rides but after that they stay tight.I screwed them right up to the backing flange and i think thats where they are supposed to be.Tom..

Could just be that the Burns are a really tight fit, problem is I don't want to just keep tightening incase I strip the thead or split the crank (Probably quite hard to do) Quote Link to comment Share on other sites More sharing options...
WeeGee Posted April 20, 2007 Author Report Share Posted April 20, 2007 Right, sort of answering my own question! Middleburns ARE damn tight but they will go on all the way. Quote Link to comment Share on other sites More sharing options...
26inch Posted April 22, 2007 Report Share Posted April 22, 2007 just tighten to the correct torque setting, for the first few rides they will come loose abit, but just retighten them, eventually they will settle Quote Link to comment Share on other sites More sharing options...
darrenhopper Posted April 22, 2007 Report Share Posted April 22, 2007 It'll be fine. Just be sure not to let it get loose enough to wiggle. That'll do all sorts of damage. Keep tightening them periodically & they'll eventually find a spot where they're happy. Quote Link to comment Share on other sites More sharing options...
tomtrials Posted April 22, 2007 Report Share Posted April 22, 2007 only time i would advise grease if they start creakin badly other than that like the other guys said keep an eye on them and tighten them up every so often Quote Link to comment Share on other sites More sharing options...
WeeGee Posted April 22, 2007 Author Report Share Posted April 22, 2007 (edited) Cheers for the advice, reason I used copper grease is because I gave in and downloaded the instuctions from Middleburn! It explained about using Grease/Anti sieze compound-copperslip QUOTE:"To ensure the crankset mounts against the backstop flange, prevent creaking and is necessary for accurate torque to be measured".I used a torque wrench but the problem was without the grease the crank sticks, the torque wrench was "giving" way before the crank was buttted against the BB Backstop! With the grease it pulled straight on and then I torqued it up properly! Jjust have to keep an eye on it now!

Jjust have to keep an eye on it now!good using a torque wrench but just take an 8 mm out with you so you can nip them up if needs be no need to have a torque setting just tighten them as much as you can and they will be fine.
