GN250 Front Chain Socket nut

[Jonah]

Hi,

I'm trying to replace the chain set on my Suzuki GN250 and I can't get the front sprocket nut off.

I've checked the manual and followed the instructions

1. Flatten locking washer
2. Lock the chain by putting on the back brake

But I'm getting no movement from the nut at all.

Before I start getting violent with this thing I wondered if I'm missing anything obvious (like the nut being reverse threaded)

Sod that -put a solid pole through ya back wheel and under your swing arm--Now loosen it

Why not just pop it in first gear? Single piston should hold it up.

I think you'll find the pole will be more use on top of the swing arm.

Take it to your local tyre service centre. They did mine with their wheel nut rattle gun for free.

I have been told few times that is not very good for the gearbox.

Didnt fooken work when i tried last, just turned the engine over and over

Is the nut reverse thread? i forget

It will be high strrength loctited. Suzuki like doing that. You can either carefully heat it up with a oxy torch, or just use a big breaker bar and gorilla muscles.

It'll get there eventually if you twist hard enough.

Yea um er well oops -bucha get the point though

[FilthyLuka]

Yeah, i had this same problem

Locked the rear wheel with a metal bar, put a meter long 1" drive strong arm (man bar) on the nut, got a 100 kilo wookie to stand on it. Went CCRRAACCCKK when the loctite gave...

You will probably snap anything under 1/2" drive

use a smaller socket and place it on the nut then hit the back of the socket with a hammer hard but dont miss . it sometimes breaks the lock with the shock of hitting it

emphasis on carefully heat it up with a oxy torch. You don't want to start munting main shaft seals

Though if there's access to Oxy then there's probably access to air driven tools too. So scare the buggery out of it with a rattle gun, all you need to do is shock the nut loose from it's binding agent whether it's loctite or similar or just bonded by contaminants.

When you put the new sprocket on, clean the thread & nut thoroughly and use a slight smear of coppercote on the thread, torque it up to the specified setting and bend a fresh locking tab from the locking washer
