Ingah Posted May 21, 2009 Posted May 21, 2009 To summarise my story: i've taken off the nuts that hold the rear sprocket in place and now i'm trying to put them back on but when I turn the nut the bolt is turning with it! So they aren't tightening. Have tried to hold the bolt in place with a screwdriver but that doesn't work. Tried banging it with a hammer too - even tried to chisel a slot in the bolt with my screwdriver, no joy. Any ideas guys? Quote
Guest Posted May 21, 2009 Posted May 21, 2009 What shape is the head of the bolt? How much room you got to work in? Quote
Ingah Posted May 21, 2009 Author Posted May 21, 2009 Bolt is a circle shape and the nuts are hex shaped around the outside and again circular in the middle. Bolt is about 10mm diameter. have got 3 to do and can fit a flat head screwdriver under the nut on one but tried putting pressure there whilst turning and no joy. Quote

Ingah Posted May 21, 2009 Author Posted May 21, 2009 The sprocket is already fitted, although the wheel is off the bike.I removed the nuts with the intention of taking the sprocket off (to allow me easy access for cleaning), but i forgot there was a curclip also holding the sprocket on, which i don't have the tool to remove. So i tried to screw the nuts back on, which is where i've come unstuck.After googling locktite, it appears that it is some sort of adhesive. I don't want to glue the nuts back on or else i'll never be able to change the sprocket again! (unless of course, the locktite is easily removed?)This isn't my bike, but as it's very similar i've drawn arrows to the nut/bolt things that i can't tighten. Quote

(unless of course, the locktite is easily removed?) is there anyway of holding them from the other side...?can you get the nuts off? if so, then undo the nuts and unwind the threaded rods / bolts otherwise known as studs, you apply locktit to these locking them in place.. then when you fit the nuts they stay still.. basically you need to get the studs tight first....a circlip can be removed with a small screwdriver being prised underneath the edge, but cover with a cloth to stop it pinging off into oblivion... or springing into your face...

Ingah Posted May 21, 2009 Author Posted May 21, 2009 is there anyway of holding them from the other side...?No, afraid not, because they go into the wheel hub (is i believe the word), and even from the other side you can't get at them - the only way to get to them would be to take off the sprocket!can you get the nuts off? if so, then undo the nuts and unwind the threaded rods / bolts otherwise known as studs, you apply locktit to these locking them in place.. then when you fit the nuts they stay still.. basically you need to get the studs tight first....I getcha, but looks like i'd have to remove the sprocket first so that i don't glue the bolts to it tooa circlip can be removed with a small screwdriver being prised underneath the edge, but cover with a cloth to stop it pinging off into oblivion... or springing into your face...After previously watching my mechanic struggling for near an hour with this method (he'd left the correct tool at work or something), i'm not too eager to try it out myself (although thanks for the suggestion). Do you know what the name of the tool i require to get it off easily? (trip down to Halfords to buy said tool i guess). Looks like i'll have to undo them nuts again and take the sprocket off, then sort it all out so it stops driving me crazy (i vaguely remember my old mechanic struggling with these nuts too when he changed my chain and sprockets so it would be nice to sort them once and for all!)
