help with removing parts

[alanw89]

im trying to take my bike to bits and replace some of the parts(my bikes 3 years old and never had any new bits) but i cant get the swing arm or the cranks off. Is there any method to removing these bits or are mine just stiff.

this is the bit for the swingarm.

The cranks

Also what is the name for the dark metal bar that the cranks are attached to because mine is a bit mangled and my pedals keep coming loose so im going to get a new one.

Thanks in advance

Not sure about the swingarm (what bike is it?), but the crank will need a crank puller Id imagine, a specialist tool you can get from most bike shops, something like this

The axle / bearings that the crank/pedals rotate on is called the bottom bracket, this will be what keeps coming loose Id think. Yours looks like a square taper design from the pics

Its a CBR Thunderace. I dont think its anything decent, i got it about 3 years ago when i was more interested in how it looked but now im trying to make it a bit better, only thing is i think its got a pretty heavy frame but i cant afford a new bike just now so ill just have to put up with it.

Heres a picture of how it looks just now dont have any pics of it all together.

Yeh it does look rather on the heavy side, my brother's girlfriend owns something similar that came from Halfords and it weighs an absolute ton and fell to bits quite quickly

Are you planning on some serious riding with it once its built back up? If so, rather than spending money on bottom brackets etc have you considered buying a complete bike second hand? You could pick up a few year old Specialized Hardrock or similar for ~£100 which would be FAR nicer to ride and maintain.

nope im not planning any serious riding once i put it back together. I actually do most of my riding on back roads and country tracks not any proper trails, (There isnt any trails or i know of nearby)i was planning on saving up money for a hardtail in 6 months maybe because its probably more suitable. This ones only getting taken apart to get rid of lots of squeaks and rattles and all the gunk thats built up.

[Locoblade]

Yep, unless you've got the best part of £1k to spend on a bike, then the general concensus seems to be to stick to hardtails regardless of the type of riding you do.

Right, now im thinking about putting it back together i realise i need some good grease because i wiped it all off when i took it apart. so can anyone recommend any good grease or something and a site where i can get it.


Thanks in advance

Hello, Your local independent biek shop is the best place for grease and tools like crank pullers etc. They will also furnish you with good coffee and good honest advice. Steer clear of the multiples - they havnt a clue!!
