Sprockets and chain

[StuMiller]

How hard is it to change a front and rear sprocket as well as put on a new chain? Any special tools required? I've got the standard range (socket set, shifters, etc)...

Any threads that can assist as I'm thinking of changing the the front sprocket and going down a tooth for better take off?? (I'm pretty sure that's right) and less top end speed?

Any help is appreciated.

Cheers.

Robracer's guide was pretty good....

Reasonably easy job mate. The only issue could be cracking the retaining nut on your front sprocket. They can be bloody tight.

I had all sorts of trouble pulling mine off (no smart arse comments please). In the end we used a big breaker bar with about a 1.5 metre length of pipe on it. I swung of the end of that while a mate sat on the bike with his foot firmly on the brake.

As Stace has said, some are stoopidly tight. When i did the Zed we had the breaker bar on and it was lifting the back of the bike up - with 95kg ON the bike. If you cant get it go to a tyre shop or good workshop, they will whip it off for you no problem. Then you can go home and complete the job.

If you have a compressor, that usually gets the front sprocket off, don't use this on the rear sprocket!. A chain tool works wonders. Splitting the chain = grind off rivot and punch out the pin (chain tool or centre punch). Putting the plates back on the link is a bitch unless you have the correct tool and compressing the rivot is also better with the correct tool. I got a chain tool for $90 that does each step and turned a 2 hour job into a 10 minute job.

Where can I buy a chain tool from?

From memory there are a few shops all close together in Hobart - one of them surely would have one. I have had mine for 10+ years now so they are a worthwile investment.

UMMMM Mike, A compressor won't do SWA without the rattle gun to attach to it You'll need a big arse compressor and rattle gun though. The $100 specials won't even blow wind up its arse (No pun intended)

Most good engineering supply shops have chain tools.

Try Blue Point 1/2" drive impact gun @ 780 ft/lb. It will even remove Staces bolt

I got a $150 compressor from Supercrap Auto, came with a free tool kit including a rattle gun - this has never failed to remove a front sprocket (CBR600 several times, Zx10r couple of times and one of Eelco's bikes either Crim or Gixxer). Last front sprocket change two weeks ago, compressor is around 4 years old

Getting vice grips which fit snuggle between the two pins has my plates on in seconds
