JaMiE.oNzA Posted July 30, 2009 Report Share Posted July 30, 2009 (edited) Hi guys, ive managed to round the nut off on my internal tensioner of my onza pro .Does anyone know a method of getting it off?Its originally a 10mm nut, ive tried using a 9mm spanner but its too small and a 10mm won't grip the nut.Help and advice very much appreciated.Thanks for your timeJamie Edited August 16, 2009 by JaMiE.oNzA Quote Link to comment Share on other sites More sharing options...
RossMcd Posted July 30, 2009 Report Share Posted July 30, 2009 Try using mole grips They should offer optimum grip on the bolt and get it off no problem Quote Link to comment Share on other sites More sharing options...
JaMiE.oNzA Posted July 30, 2009 Author Report Share Posted July 30, 2009 Try using mole grips They should offer optimum grip on the bolt and get it off no problem i dont think i would be able to fit mole grips in the tight space, its one of onza's worst designs i think. its really hard to access with an adjustable etc Quote Link to comment Share on other sites More sharing options...
RossMcd Posted July 30, 2009 Report Share Posted July 30, 2009 What about a pair of needlenose pliers? I know you get needlenose mole grips which would work im sure! Quote Link to comment Share on other sites More sharing options...

Sam Nichols Posted July 30, 2009 Report Share Posted July 30, 2009 Am I right in thinking it's a long threaded rod that the nuts on, and the other end is simply threaded into the frame/other end of the tensioner?If so there should be enough poking out so you can get a mole grip on there and unscrew the whole thing with the nut still on. That's a last resort though as you'll chew up the threads. Quote Link to comment Share on other sites More sharing options...

craigjames Posted July 30, 2009 Report Share Posted July 30, 2009 Its not a bad design at all, you were evidently using the wrong tool or using it incorrectly. Can you get a ring spanner on it if the bolts not completely rounded? Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted July 30, 2009 Report Share Posted July 30, 2009 It's just a bit fiddly getting the spanner in place, using the open end is obviously easier to place over the nut, but as the chainstay blocks the spanner from sliding all the way over the nut, it has a reduced contact area and therefore grip on the nut, thus slipping.Mine are slowly getting that way.

craigjames Posted July 30, 2009 Report Share Posted July 30, 2009 Swap for an allen bolt once you get them out Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted July 31, 2009 Report Share Posted July 31, 2009 Swap for an allen bolt once you get them out It already is an allen bolt, the nut just locks against the frame ensuring the bolt doesn't loosen itself over time. Quote Link to comment Share on other sites More sharing options...

hdmackay Posted August 1, 2009 Report Share Posted August 1, 2009 Wait...I have a feeling I have misunderstood this... but the answer seems quite simple to me.If it's the nut that you tighten so the bolt won't move, put the 3mm allen key in the end of the bolt (the bit you tighten when you are moving the wheel back) and keep on turning it till the bolt comes out and then the nut will just fall off?
