Default Chains...

I've never fucked with mine other than to clean and tighten it... but I've ordered a new set of sprockets and a chain... that will be here next week...but as I know I'm gonna be short on time... I figured I'd get everything ready to start the process.

so I took off the rear tire... then took off the cover for the front sprocket... then realized something... I gotta break the chain to get it off... and that's when I realized another thing...

I HAVE NO IDEA HOW TO DO THIS.

I'm assuming there's a tool that will break it...

what about the new chain and the master link... do I need a special tool for that?

I feel like an idiot... but hell... ya gotta learn some how.


while we're on that topic... any advice about the process that might ease it along?

I'm still not sure how I'm gonna get the front sprocket off.... will the gears hold it enough for me to loosen it or will I need an impact wrench?

thanks

My front sprocket was supposed to be torqued to 90 ft-lbs per the service manual. NOPE. You need an impact. Break that sprocket loose before you cut the chain, and you can use the rear brake to hold it.

To get the chain off, you can just cut it with a grinder/dremel/hacksaw. Most good press/rivet tools also have a pin to press out a link pin. BE SURE to GRIND OFF THE HEAD of the rivet or you'll probably break the tool.

Easiest way to replace the chain is to loosen the front sprocket, count the side plates of the old chain, cut the old chain, cut the new chain, pin/wire/whatever the new chain to the old and pull it through- all before you pull the rear wheel off. Taking the sprocket off the rear is a nothing job- bunch of bolts around 20 ft-lbs. Replace rear wheel, press on side plates, peen rivets. Pressing the side plates and peening the rivets requires some finesse- which is why you should get a spare master link. I pressed the first one too far, and the rivets twisted and cracked. Helps to put a dab of grease on the end of the tool before you peen the rivet.

You did make sure you're getting a rivet master, Right?

I'm not sure what I'm getting... the chain will be pre cutt for me to the length I need for the sprockets I have.

ok... so I should put the rear tire back on and then break the sprocket loose? figures

thanks...

If you get a clip on style master link you dont really need any special tools. just make sure that you put the clip so that the closed end faces the direction that the chain travels, and make sure that is seated in the grooves on the pin good.

Also, if you are by yourself, zip ties are your friend, use them to hold the chain together so you can work with the ends of it easier.

Go to Home depot, buy an electric impact gun, use it to break the front sprocket loose and return it, just dont get it dirty. Also, if you are gonna use a impact gun, make sure that you have the rear brake on, the impact gun has enuff force to spin the rear tire, and roll your bike forward and off a side stand.


What would be real nice is if your base has an auto hobby shop you can use. The guys that work there can usually give you a hand.

And you do know that you can get away without a new chain, just buy a 1 or 2 tooth larger sprocket, and your chain can stretch a few more inches before your replace it. (Please dont take that serious, I heard of one local guy that actually did that and his chain snapped on him)

I've figured an easy fix for this. roll your bike's front tire up against a sturdy wall first when you park it, then you can pull the nut easy. it cant go forward when theres a wall in front of it.

The first time I replaced a chain I wasn't so smart and I had a bike laying on me a few seconds after I started to use the impact gun. The bike wasnt damaged though, it landed on me and I didnt scratch it.
