Axle Nut size? Empty Axle Nut size?

Post  northun_munky on Thu Aug 12 2010, 13:20

I'm looking to attempt to tighten the chain on my 'cat as it is tres loose. I've studied the haynes manual but I'm falling at the first hurdle as I dont have a socket large enough...

What size will i be needing?

Cheers in advance

do you have the toolkit under the seat? there is a spanner with an extension piece to get you by until you get a socket. Do you have a torque wrench if so rear axle nut is 117nm.

Yep 24mm and 117 Nm.

If you don't have a torque wrench then it is ARGH hard as I bloomin can tight without an extender (pretty much).

With an extender it is 'still quite a bit of effort' tight (pretty much)

Cheers guys,

I don't have a torque wrench so I'll give it the quite a bit of effort tight with the extender. If I have a toolkit that is! lol!

*BUMP*

How did you get on with the chain tightening??

Just got home after work and thought something didn't feel right (didn't know what but impressed at thought anyway!)

Anyhows jumps off bike once home and decided to check the chain, bugger, it's that slack the play allows it to go up and touch underneath swing arm and feels still could go bit further!!! Rolling Eyes Rolling Eyes

So this weekend lookin at tightening the chain, looking at rear axle theres plenty of room to play with, do we think should work or does that sound far to slack to be good and possible new chain/sprocket ?? As previously mentioned i'm as much use as trap door on canoe when comes to mechanics but thought might try this one meself, god help me!!!

Any help greatly appreciated, great

Sounds a bit loose, mine was adjusted like that after the tyre change and I wasn't happy.

You may find gear changing not as smooth as well as other issues, the right 'tension' seems to be important on the 'Cats.

When you do tighten it, turn the wheel and check - do this a good few times. New chain if you have some slack and other times too tight. In any case good time to also clean it and relube.

I never seem to get the nut re-tightened properly.

Thats what thought, just felt dodgy ride home for some reason, might try tensioning first then keeping eye on it to see about replacing altogether, cheers! Very Happy

Nowhere near touching the swing arm now, there is about 15mm movement whilst on sidestand, can see exactly how slack it was just seeing the standing position of chain, was hanging about 3" below swing arm and now perfect straight line between rear and front sprocket, and like i say didn't realise why it felt dodgy before hand but can tell after, it is picking the throttle up straight away, and pulls lot better!
