changing chain and spockets

[Mysuzyq]

A 530 chain will actually FIT a 630 sprocket, enough to hold it in place. N1Elkyfan mistakenly ran a 630 chain on a 530 front sprocket thru a whole rally...

Good to know, TCK! A 530 chain on a 630 sprocket may or may not have lasted the whole rally for N1fan though.

What he said.

Putting the old chain on is what I'd do. However, instead of clamping it to the swingarm, use some bailing wire and tie the chain together. A few wraps of that stuff will hold it long enough to break the chain free.

2 things you could try Bert. A spanner wrench would work. It would grab to the teeth. Or, and if youre trying to save the old without gouges in it, I wouldnt recommend this one BUT You could put a pipe wrench on it. A large 18" one should larger enough to hold it and you can just snug your foot against it while you hit it with a impact.

I dont' know why, but I've never had a spanner wrench. I gotsta get me one.

[QUOTE=renobruce;1069579]I'll watch with baited breath. I have one that needs to come off, too. The trick is to loosen the nut while the chain is still on..with the back brake applied.

Count me in as one on the watch list. I just ordered the 530 conversion set-up today, so sometime next week I will be doing this as well.

Hopefully, the threads are right-handed yes? Nothing like trying to loosen something that is left-handed instead of the customary right-handed threads.

Well, between here and Jeff Saunders, I thought I had it. Put the new rear sprocket on, but the wheel on, looped the chain over the sprockets and had my wife stand on the rear brake...........and I tried and tried with my ratchet and 24" pipe............fortunately I have two other ratchets, since I snapped that one in half - it was old and my favorite.........tomorrow, I buy an impact wrench.

I got 24,000 miles out of the last chain and maybe that was just too long to wait.

I use anti-seize on darn near every threaded anything. I had zero problem getting mine off after 15+ years!
Take the bike to someone with a 3/4" drive gun. 1-1,200 pounds of torque in reverse. Do NOT use it to tighten (break off) the nut on the crankshaft!
Then, you will need a new crank.

I just did mine on Saturday. I used a Snap On 1/2" cordless impact and it came off in about 1.5 seconds. I forgot to bend over the lock washer and the impact perfectly smoothed it out as it spun the nut off.

One thing though that bothers me. The old sprocket had two metal discs attached to it with three screws. The new sprocket from Z1 only had one hole with the right spacing to accept the screw. It is holding fine for now but I'm not sure if that is proper.

By the way, what a difference, the bike is so much more quiet and more responsive.

That is for noise dampening. You don't need it.

A 2' breaker bar with a 4' pipe on the end is usually sufficient. LOL

Leverage? You don't need no stinking leverage.

One of my favorite tools...

Did have anyone close to borrow from?

Not really - everyone I know here just takes their bikes to Bill's. I don't mind buying a tool, though, and I think I can manage with a 1/2" - a cheap one. I assume I have to buy a socket specifically for the wrench (rather than just use my own 32mm).

[MikeG]

You can use a standard chrome socket. The impact sockets are for guys who use them all day long. They are softer and will give way before a valuable fastener or expensive impact gun anvil. For occasional use you should be just fine.

Excellent.....I don't see changing occupations in my near future. Even though I've had this urge the past few years to do my own work on the bike (mostly from seeing the incredible work people here have done), I'm a little late to decide it's a 'calling.'
