Sigil Posted October 19, 2011 Posted October 19, 2011 I am unable to losen the nut that connects the rear wheel so that i can adjust my chain. I am at university and dont have meny tools. i have a torque wrench that i will use to tighten it once i have adjusted the chain. but i am unable to losen the nut itself. when undoing the nut the other end rotates (quite alot of force needed) but when using the spanner that is supplied with the bike (small in length). the torque wrench maxes out at 200 Nm. I have noticed that the rear wheel is slightly out of alignment as well... bit annoyed as i got the bike from a dealer and they fitted new tires so have overtightened and miss aligned the rear wheel... I am ment to be going home on the friday plymouth to reading so quite a reasonable distance. If i cant get it sorted out at uni we have some decent spanners at home and know a couple of keen bikers that might be able to help me sort this out there.but ofc i would prefer to know my chain and rear wheel are correct for the journey... you guys (and girls) have any recommendations or ideas? i am heading out to get some WD40 to try and losen the nut now.Thanks.

Sigil Posted October 19, 2011 Author Posted October 19, 2011 sigh just realised i should of put this on the pitstop section so if a mod can move it for me Quote
Boro Jake Posted October 19, 2011 Posted October 19, 2011 Get a haf inch wrench then get a pole to get some leaverage on it.. Also helps someone else on the other nut Quote
GazW Posted October 19, 2011 Posted October 19, 2011 All else fails, if your uni has an engineering department, ask to borrow a blowtorch, gently heat the nut. Or ask if they have an impact driver. Quote
iWannaGoFast Posted October 19, 2011 Posted October 19, 2011 Had the same problem with the adjustment bolt.Guy at my local bike place ended up getting an oxyacetylene torch on the bugger. Quote
megawatt Posted October 19, 2011 Posted October 19, 2011 Don't need a gas torch anywhere near your bike . Just borrow a spanner or large mole grips to hold the other end of spindle and a length of steel tube to slide over your spanner to increase the leverage. Quote
Colin the Bear Posted October 19, 2011 Posted October 19, 2011 Two spanners needed. Sounds like your axle is a long bolt with a nut on the end. Hold one end with the right sized spanner. A ring spanner is best if you dont have a socket. Whilst holding the bolt end unscrew the nut with another correct sized spanner or socket.Some axles have a pin through so the nut can't work loose and drop off, others use a locknut, an extra nut on the end.I wouldn't use your torque wrench for general tightening. It's a precision instrument , not a work horse.Tapping, emphasise tapping, the nut end spanner with a mallet will help to undo the nut. Don't let it slip and round the nut. You know what to ask Father Christmas for this year, socket set etc Quote
BikerBoy414 Posted October 19, 2011 Posted October 19, 2011 ah nuts. the overtightened nut, mans natural enemy haha yay. oh great. first off, what your gonna need is two spanners. Sounds like your axle is a long bolt with a nut on the end. Hold one end with the right sized spanner. A ring spanner is best if you dont have a socket. Whilst holding the bolt end unscrew the nut with another correct sized spanner or socket. haha j/k i just copied it lol oh great now im cool lol Quote
mealexme Posted October 19, 2011 Posted October 19, 2011 I just undid my front wheel lol. Used molegrips and a socket wrench. I dont think molegrips are recomended as they can destroy the nut if you use it over and over again because theteeth can round it offI cant loan you the molegrips as theyre not mine, but I can give you the socket set for a bit if that helps? Depending on when your going, because im not planning on going to plymouth again till friday lol (the course im doing should end at about half 2) if its any help? Quote
Boro Jake Posted October 19, 2011 Posted October 19, 2011 Its a rear wheel, the garage will of tightend the nuts right up as they should. From what it sounds like your tools are the problem Quote
XmisterIS Posted October 19, 2011 Posted October 19, 2011 As others have said, you need a longer lever - spanner and a length of pipe to increase the torque that you can apply.Also, do they not teach spelling and grammar at Uni anymore?!(coat ... gone ...) Quote
Sigil Posted October 19, 2011 Author Posted October 19, 2011 cheers for the responses surprised there was so meny i think ill leave it till i get home and use some decent spanners, ill put some WD40 on it now so that it gets time to soak in a little. Tools cost so much , need to slowly build up a set... do love the idea of being able to fix/maintain most things on the bike tho and cheers for the offer alex but ill go home and see if i can sort it out there Quote

It may take a bit more time than a garage, especially without a manual (The forum is my manual, thanks guys/girls) but it will save you a lot of moneyIts surprising what you can do with a socket set, a wrench, a screwdriver (normally flat head) and a megawatt(sp) (other members are available )Also no worries As others have said, you need a longer lever - spanner and a length of pipe to increase the torque that you can apply.Also, do they not teach spelling and grammar at Uni anymore?!(coat ... gone ...) sigh, my spelling is unbelievably crap... always has been. but im going to be a engineer so hopefully its acceptable along with the bad handwriting and being a bit boring lol so yeah deal with the spelling and thanks for the help ^^Or a doctor Quote
uk190 Posted October 20, 2011 Posted October 20, 2011 be very careful when letting anyone near your bike with a blow torch.it is easy to boil the grease out of wheel bearings etc i am not saying that it should never ever be done. just makes sure they/you are careful. Quote
megawatt Posted October 20, 2011 Posted October 20, 2011 You will need a small number of spanners anyway mate. Adjusting the chain is regular , essential maintenance, which should be done BEFORE a long journey. I'm certain that, someone will lend you the tools, IF YOU ASK. Get it done NOW, before you have a major problem on that long homeward journey. Quote

Get it done NOW, before you have a major problem on that long homeward journey. I'l put my socket set in my bag encase you change your mind. No inconvenience to me either way because I am taking my rucksack into plymouth with me tomorrow anyway. Cant garuntee it will fit though as I use the parents adjustable spanner and mole grips for the rear axle... lol (que techno and other experienced mechanics to tell me I need a torque wrench )But if you do change your mind, as I said, my course in plym finishes at half 2. I will pm you my number just encase Quote
Sigil Posted October 20, 2011 Author Posted October 20, 2011 I would like to do it before i go but really dont have the time, going to be leaving at 2pm and dont want to rush home.Cheers for the offer alex but i think i will need to do it when i get home. The chain is not that lose but is on the limit of the 35mm slack allowance (its 25-35mm slack recommended) and just wanted to put it another 5mm tighter, altho i think the alignment is slightly out... what is quite annoying considering the shop changed the tyres for me and i have only done 500miles it really shouldent need altering again. I need to be heading back after university so i think ill get it sorted at home (going to take the torque wrench back with me). Quote
Guest philgale Posted October 21, 2011 Posted October 21, 2011 When you say the wrench maxes out at 200nm its not torqued up to that is it? i hope its not book says on mine 120nm i think off the top of my head... Quote
Matt Strange Posted October 21, 2011 Posted October 21, 2011 I have a 2 foot 1/2 inch drive breaker bar = no such thing as a nut I can't undo on the bike http://www.halfords.com/webapp/wcs/stor ... yId_165469^^^^a brilliant piece of kit ^^^^ Quote
Boro Jake Posted October 21, 2011 Posted October 21, 2011 Amazes me people buying cheap tools to maintain there bike when they run the risk of rounding nuts off and spending expensive garage bills to sort it out Quote
Sigil Posted October 24, 2011 Author Posted October 24, 2011 got the bike sorted now. went home and still couldn't undo the bolt with some proper spanners so took it to a local garage. basically the guys who changed my tyres at the shop managed to over tighten the bolt, have the rear wheel out of alignment and have the axle bolt on... backwards.... >< and this is there job, not happy tbh.But its all sorted now Quote
Fozzie Posted October 25, 2011 Posted October 25, 2011 When they did the tyre change on my CBR they screwed the alignment, chewed the paint off the rim a bit and then said it was like that when it came in 27mm spanner on ebay for £6 made by Silverline. Tools are cheap as sin mate. Ebay it! Spend £50 and you'll have all the tools you should need for doing all the general servicing needs Quote
