Bicycle repair and maintenance for the regular bike rider. No frills here but the basic stuff everybody needs to know that can help you save money and have fun. So from where ever you are on this planet, read on,fix it, get on your bike and ride!
There wasn't much left on the bike but I still had to get it down to the bare frame. First thing to go is the fork. I'm not planning on using the bike in trails anytime soon so no need for the extra weight of the suspension fork. It will be replaced by a leaner rigid fork.
Removal of a threaded fork is quite easy. After removing the stem by unscrewing the top bolt a few turns, punching it down with a hammer and pulling it out, you can start removing the fork by unscrewing the locking nut, that's the real big one. Then the rest comes off easy, the washer, unscrew the bearing cone off and then just slide the fork out. The bearing cups on the frame can be removed by gently tapping them inside the frame with a hammer and a long piece of steel like a worn out screwdriver. I've re-installed all those components back on the fork afterwards for storage. Until I locate a decent replacement fork, I don't want to lose those bits in my shop somewhere.
Next up is the crank arms and the sealed cartridge bottom bracket. Here you need bike specific tools like the puller and the sealed BB socket. There's no going around those.
To remove the cranks, start by taking off the locking nuts inside the crank arm with a 14mm socket wrench. Before you insert the puller tool, lubricate everything that moves on it. The friction you are about to create is the enemy of that tool. Protect your investment and make the job easier by taking a few seconds to do this. Clean the threads in the crank arm with an old tooth brush before you proceed. Screw the tool in by hand all the way in. If you are having a hard time doing this by hand, you have dirt in there, clean it again. If you don't screw it all the way in, you take a chance of pulling the threads out and if you do that, YOU are screwed! Once you have all that done, turn the handle and the arm should come right off.
Next is the sealed bottom bracket cartridge. Insert the special socket on the chain side and go clockwise in order to unscrew it. The thread is reversed on that side of the bike. Once it's out, remove the cartridge and proceed to remove the holder on the other side by unscrewing it counter-clockwise.
My seat post was stuck, so I installed a seat on it to use for leverage and managed to pull it out easily.
The last thing left to remove was the stickers. The best way to go about that is to heat the sticker using a hair blower on the warmest setting. This will melt the glue partially and help you remove the stickers with less residue on the frame. Whatever is still left can be removed with WD40 or other stuff made for that.
That's it for now. Next step will be to prepare the frame for primer and paint.
I'm a guy with a passion for bicycles, plastic models and general homebuilt mayhem of all sorts. I wish to share my knowledge with the world and help you out in the process. I live in Canada – the best country in the world for cyclists but don’t just take it from me, book yourself some holidays to Canada and see for yourself!
