DIY: Chain and Sprockets

[ad_man53]

This is for the same size sprockets, if u are changing the gearing then do the rear sprocket before the. chain

1:- First step is to loosen the rear wheel and push it as far forward as you can.

[ad_man53]

2:- now put a screw driver under the lock washer and bend it up. if u have a rattle gun it'll be easy to get off as u can just hold the rear wheel and undo it, other wise u are going to have to hold the rear brake as u loosen the nut.

[ad_man53]

3:- now pull off the nut and the washer, and pull off the sprocket.

[ad_man53]

4:- Now put on the new sprocket and put the washer on and make sure it goes on properly.

[ad_man53]

5:- Put the nut back on and do it up, then bend the lock washer over so if the sprocket nut doesn't fall off

[ad_man53]

6:- now get some pliers and take off the split link, and pull it out.

[ad_man53]

7:- then drop the bottom half of the chain so it looks like this.

[ad_man53]

8:- Now join the new chain to the old chain with the slipt link and crab the bottom half of the chain and pull the chain around.

[ad_man53]

9:- when i join up the chain u can see there is left over and the links don't join up right,

[ad_man53]

10:-Back the chain off one tooth so that 2 inside links are next to each other as in the pic, and mark the the one that needs to be cut off. (The first outside link)

[ad_man53]

11:- then drop the bottom half of the chain again and place the chain around the sprocket and grind off the buldges on the link u marked.

[ad_man53]

12:-Put a a screw driver between the link's and pop off the outside plate. It won't just fall off so wiggle it around a bit

[ad_man53]

13:-Pull the link out and line the chain up again and put in the new split link.

[ad_man53]

14:-Make sure it goes on this way, if it's the other way and can get caught and fall off.

[ad_man53]

15:- now pull the wheel off and take out all the sprocket bolts, then put the new sprocket on and tighten it up. Put the wheel back in and tension the chain. You can have it a little bit tighter then normal because it will stretch heaps in the first ride. Just keep an eye on the tension and adjust it as it gets loose.

good job writtig that up dude, wat bike is that? ur 125?

[ad_man53]

nah my 250f, the old chain is rusty because i didn't spray it after i washed it last because i knew i was getting a new one

[METAL_MULISHA13]

Ohh thank you Adam, your a great help!

Next time i need a new chain or sprockets ill read this again! This is another sticky up the top again! :D

[nutty professor]

1) Grind the plates off in a vice, that way the iron waste goes on the floor and not into the grease on the brand new chain

2) Loctite the sprocket bolts and the countershaft nut.

3)Use a torque wrench and the factory torque specs

Is there any easy way to tell that a chain is worn & should be changed ? I've snapped a chain going over a set of doubles & ate shit pretty hard, now I'm paranoid I'm going to do it over my ramp. Is there any easy way to tell when I should replace a chain ?

the propper way is to take the chain off and messure the elongation ie, the difference between fully compressed to fully extended can remember the exact limits check your manual......the easy way is to pull on a link thats on the rear of the rear sproket if it shows more than 1/2 a tooth its worn.

Thanks buddy !

ah kool, ive never seen this forum before and its good to know i do it pretty similar to this

[610]

thats pretty comprehensive. but heres a question, went riding in clay and mud now my whole bike is caked in mud. have taken the chain off. is there a way to clean it really good. i.e. bath it in fuel or something. obviously holding off until someone gives me tried and proven advice. as fuel may eat the o rings or something. though i dont think mine is an oring chain.
