Chain and sprocket adventure - Front sprocket advice

So I finally saved up my pennies and bought a chain and sprockets. Yay! I'm all excited about putting them on, but I can't get the bolt on the front sprocket loose. Fudge!

Do any of you lovely gentlemen have some quick and dirty advice for popping this sucker loose? I suppose I ought to mention that I poked a metal bar between the swing arm and the wheel to keep it from spinning, I just don't seem to have the muscles to loosen the bolt.

I haven't been riding since May and I'm about flip my lid if I don't get some saddle time soon. Aack!

Is the chain still on the bike? When I did my 17t sprocket i just put the bike in first gear, put a socket and ratchet on the bolt and put a little foot power to it and it came right loose, If I recall it should'nt have a huge amount of torque holding it together

Yep, chain is still on it. It keeps moving on the rear stand when I try to loosen the bolt. I suppose a smart person would put it back on the ground to dick with it, but I have only just realized that.

Yeah, having the rear wheel in the air kinda defeats the holding ability of the drivetrain

It must be the heat. I swear I'm not this dumb in real life.

A cheater pipe is your friend. I use a 1 1/2 ft piece of thick copper pipe that will fit over the rachet. Make sure the bike is in gear. Sit on the bike, put the rachet on the bolt in about the 3'oclock position then slide the pipe over the rachet and reach down with your left hand and pull up on the pipe. Should give you enough leverage to break it loose fairly easily. Also helps to hold down the rear brake so the bike doesn't try to lurch forward when you're pulling. Hope this helps!

Breaker bar with a piece of pipe over the end for more mechanical advantage or if worse comes to worse, an impact gun.

Here's a novel approach for the front sprocket:

I'm not fond of using a rachet to break fasteners of that size loose or letting the transmission hold back the torque. I use a broom handle through the rear wheel against the swingarm.

Are you going with a rivet(staked) or clip type master link?

I'm going with the rivet type.

I've been watching the vids from these guys, and they seem quite helpful. It just sucks that I got stuck on the first step.

But the good news is I got the dang bolt free! I don't own a cheater bar, so I shoved a piece of metal down a piece of PVC, slid the nonsense over the wrench handle, and crossed my fingers that my shenanigans would work. Probably super-unsafe, but it resulted in success and nobody lost and eye.

I pondered which is was when I made the post. Thanks for sorting me out.

Thanks to all who offered advice on helping me bust a nut. The bike is back together and I'm pleased as punch.
