My manual tells me when I need special tools but doesn't say anything about removing/fitting the front sprocket.

As it has a squared section on the outside and the nut section on the inside, do I use a long socket or something on the square section ?

Do you have a photo John? I'm guessing it's a bit different to the earlier 9's going off your question.

and that's when the trouble started...........

mate, they use a massive robot to install these at the factory, with something like 300nM applied ( or at least it feels that much..)

You can use a long breaker-bar on the right-sized sprocket - bung a big piece of timber in the back wheel so it locks up against the swingarm - say a couple of prayers and heave your guts out. Good luck.

When I did Mel's front sprocket a few years ago.......the workshop took 2 goes with the gas-axe to get the fucken nut to loosen up. Its a nightmare. If your sprocket has already been done, then maybe the breaker bar or an air rattle-gun will do the trick.

This is my problem...could just use a nut but want speedo drive (uses the square bit for the pulses.

Make sure you used single hex socket, ohhhh and rattle gun for the win. It takes 2 minutes to swap it with a rattle gun

ER6n is the same. Lotsa swearing to get the fukker off. Rear brake on, extension bar jammed in sprocket (new ones getting fitted afterwards) and a complete fukker to get off. Rattle gun didn't work. BIG breaker bar did. eventually.

Definitely don't have one of them on my 9 and I would stay away from the square section when you're trying to loosen it, unless you want to shear the sucker off that is. Looks like you need one of those 6-point deep impact sockets. I bought one from repco for about $30 to remove the drive shaft lock nuts off the car to replace them. I always use a big piece of timber through the rear wheel and against the swingarm like Gos said and breaker bar. Makes a lovely big cracking sound when it finally lets go too and for a split second I always think I've broken something.

This is the socket I use.

Yep that's the socket.

27mm socket on most.
I did Hoffy's the other week. And even with a shithot electric rattle gun, it took a good 5 seconds before the nut started turning.

I shit hot 1/2inch electric rattle gun will have up to or about 400nm of breakaway torque. So if the nut if done up to about 300+ it may take a second or 2. Where as good air gun will start at 500nm and go well above 1000 depending on brand.

I took mine off the other day using a shit hot cordless rattle gun and t only took about 2 secs and that was factory tightened.

Don't try to use the square section, whatever you do. It'll just collapse and stuff the nut completely. The bit I could never understand is why the hex section has rounded corners from new.

Yep, all the above in particular the deep socket Kev posted..
Before I got a "shit hot" rattle gun, I use to have the misses on the bike standing on the rear brake, a block of timber thru the rear wheel and use breaker bar. Busted a couple of cheap sockets doing that too...

I never found it that hard, Ride out to Glenn's and get him to take it off, easy as!

Have rattle gun so just need socket.

You mean trailer it out!

Or better still just call him as the bike is there anyway

Look for Kinchrome 4wd hub sockets in stores like auto pro. There's a few different sizes and they're just like the one in the picture.
