x-ring chain mischief

[Jace009gs]

How do you get the countershaft sprocket off? [aka little one] I have tried to hold the chain while a buddy puts the air impact wrench to the nut but with no success. alls I get is a booboooble..FYI my air impact is not a "heavy duty unit" and maxes at 85ft/lbs...whis is plenty i think in this case but ya....The threads are reversed arn't they? I would feel like a super Dork if they wern't...meaning to loosen up the nut I need to go clockwise and to tighten the nut down I need to go counter clockwise. due to the fact that the engine spins clockwise.... :dunno:

Front sprocket? Circlip not nut on GS500.  My old GS450 was a held on by a nut.

You're very lucky you didn't have access to a larger rattle wrench.

Easy, get it in gear, stick a rod across the swingarm ... then air away ... BTW GS is a clip like he pointed out ... other bikes have nuts ...  :lol:
Cool.

I don't know where you see the need for an impact wrench to remove the front sprocket.  The last time I saw it, it looked like this:


I documented what I did in my Adding a Tooth -- Going Up to a 17T Front Sprocket thread.  No wrench required...

Okay, show us yours.

my bad my bad forgot to mention it's for an Yamaha FZR 600 bike not a gs... :lol:


trust me it's a big old nut 1 and 15/16ths

I got a mate to push on the rear brake pedal to immobilise the rear wheel
then used a socket and a long breaker bar to take the sprocket retaining nut off my GSX400.
You'll need to still have the chain on for this to work obviously.
If the wheel has good strong spokes then the bar through the wheel and across the swing arm may be a better option.

It wont be 15/16ths more likely its 24mm, jap bikes are all metric. You do need to use the correct size tool otherwise you risk damaging the corners of the nut them you really will be screwed.

sledge ya I can't read the socket size...must have been soem junk on it    but yes before I blasted it with the heavy duty impact driver I doubled checked the size.... no no it's a a huge gigantic nut. amost 2" in diam. 1 and 15/16ths

I can assure you that a 90psi air line and a 3/4" drive air impact driver will free up any bolt hehe and sheer auto lug nuts off like toys ....it took more muscle to hold the driver up than to hit the trigger and woooomp the nut was off.

My drive line is all assembled and back on the bike except for one small tiny important piece...How do you guys compress the x-ring chain seals to get the master link/connector pin link in? Do they make a special device for this application??? there is only so much room and my fat hands seems to only beable to compress the seals a little and i can get the side plate on but  not enough for the master clip

4-foot long channel locks.

[Jace009gs]

ya then just clamp down on one side???...get the clip in then get the other side compressed in completing the clipping on the pin...any other methods?

[scratch]

Use the chainbreaker*...just back off the center pin remover, and then re-seat it lightly to keep the pin from backing out of the plate (don't ask how I know), and see-saw the plate on alternating tightening the plate 1 and a half turns each end.

*unless you used a Dremel

But, really, you can solve any problem with 4-foot long channel locks.
