Gearbox Sprocket, wot thread!
 

Hi can someone advise me, I am going to do a chain and sprocket change on my XT660R and I've got all the relevant bits (hard hat, goggles, big hammer, ear-defenders for the missus) but can someone tell me before I start is the gearbox sprocket retaining nut left or right hand thread.
Cheers

Right hand thread.

I changed the chain and sprox on mine last week. As my wife wasn't able to help, I was expecting an epic battle with the gearbox sprocket nut, involving a game of Twister with brake pedal, but it was a lot easier than I anticipated. Someone on a forum suggested putting the bike in gear and putting the front wheel against a wall (why did I never think of that before?) and with a 24" breaker bar it came off pretty easily. It's only torqued to 120NM, which is tight but not stupid tight.

One tip from past experience: use a drift or punch and make sure the retaining washer is absolutely 100% flat against the sprocket before you try to turn it. Even the slightest proudness of the washer will turn difficult into impossible.

And yes, it is a normal right-hand thread.

Hi Black Dog, cheers for that info

Got myself one of these when I changed the chain and sprockets last time.
Also needed an impact driver socket to fit on the sprocket nut, a few pounds from Halfords.

I have an old car battery in the garage that will not start the car but gives enough power for this.

It's my new favourite power tool.
Used it to remove the flywheel on the Morini for cam belt changes and it laughs at the wheel nuts on the campervan.

Hi all, I finally got round to renewing the chain and sprockets on the R and blimey, was the gearbox-sprocket nut tight, even with the missus on the brake!! ended up at the local garage and got it loosened with an air-gun, and even that was a struggle.
Back home I found on the wheel hub three of the bolt threads ends badly chewed from when the chain jumped ergo three f'd nuts (serves me right for not checking through the crud before spinning them off with a drill!!) I can replace the nuts, but is there a way to re-dress the bolt thread ends, I can't find a thread file here in France.

Ha Ha Got meself a thread file, re-dressed the bolt ends fitted new nuts, opened up the chain kit (AFAM its been in the garage 2 months) and whats this? some hollow pin type joining-link so now I'm searching for a hollow pin type joining-link fitting tool ho hum

Isn't this the type where you are supposed to roll the pin over the plate of the link? if so, pin punch!

Hi Bald_Pig sorry about the delay in replying lost the internet for a while, I did look into that with the pin punch but was a bit wary of my precision with the hammer, as luck would have it the solution presented itself, when I was binning the packaging it rattled and Lo stuck up on the inside of the box out of sight was the spring-clip joining link I had ordered so all is well and I'm clocking up the k's.

Why don't you us a split link to join the chain.?:rolltfl:
