Front Sprocket Nut....

[nasty]

How fucking tight are these things????

I tried to loosen the damn thing to fit a new front sprocket and couldn't budge the thing, neither could my mate FFS!

Going to my mates garage in the morning to get the windy gun on it.

Before I tackle the tightest of all nuts with a windy gun I have a rather embarrasing question - in all seriousness which direction does the nut rotate to loosen LOL Anti-clockwise or clockwise? I've never changed my sprockets before so I don't have a clue

Any and all insults will be taken like a man! I would like the question answered though

Hi

Normally they undo the conventional anticlockwise direction.

Make sure that any locking washer is released.

Often you have to put something through the rear wheel to lock it against the swinging arm, then put the socket on the nut, put a breaker bar on it and then put a scaffolding pole on it. Take care to avoid damaging the wheel and swinging arm and get someone to hold the bike steady.

All the best

Quite often a bar is more successful than a windy-gun. Give it a try though, it'll either work or it won't.

On my zx7r it needed my old man standing on the rear brake, the bike up against a wall, a breaker bar with a full length piece of scaffold bar, and a quick hard jolt to crack it open and avoiding spinning the rear wheel instead

It was ridiculously tight I have to admit haha

Try spraying on some penetrating lube like Plusgas and leaving it for a couple of hours. Might help.

The toughest bit is breaking that initial 'crack', a bit hard jolt should do this, and douse it in WD40 beforehand

Yeah, usually they are done up to around a zillion Nm.

Would agree that a metal bar slipped over the end of a breaker bar is the best bet, get a mate or neighbour to stand on the back brake and then you lean on the bar. Used this method on my RXS this week after the chain snapped at 42,000 miles.

The one on my Honda CBR 1000 is easy to get on and off.

The splines do all the work of transferring the power, the bolt is just to hold it in place.

Unless the design on your bike is significantly different, some pratt has over tightened it! Probably with a 'windy gun'

On my old bike the previous owner had decided to use thread lock, just in case I had to seriously heat it up to get the thing off so I had to change the seals as well.

I'm with G, I really don't like the idea of putting that much force into the final drive shaft bearings or chain.

I prefer to use the bar to a hammer-gun because I dislike putting repetetive shock-loadings through the gear clusters.

I suspect that neither is any more damaging than the other but there's a good argument for both (or not using either). A shock -loading wll require less ultimate force to release a tight fastener for sure.
