Impact Driver - Front Sprocket Removal

[Pedro1974]

Hi

Could anyone tell me if I can use a manual impact driver (Hit with hammer type) on a 32mm nut?

I’m presuming that I will need a powered one but I can’t find anything that tells me which I need ???????

Thanks in advance

Something says to me that axially belting the nut/sprocket, which is attached to the mainshaft is not a very good thing to do.

Are you wanting to use an impact driver because the nut is too tight to undo with a spanner or because the nut is rotating?

I would be wary of using a manual impact driver either way for the reasons stated above.

Edited to add - What bike?

Might be better off buying an electric impact wrench, corded are cheaper, these drive the socket round and round, instead of BASH🢂axially and also round and round.

If I were you I would put the bike in gear, get someone to stand on the rear brake, make sure there is no tab washer still bent up, put some heat into the nut with a paint stripping gun or similar for about a minute then have a go with a long breaker bar and a decent socket.

I was struggling with an air impact gun a month or so ago on a 27mm front sprocket nut, the thing was laughing it off and it was the heat bit that finally solved it, wish I'd done that the first time. It flew off after the heating, felt like I could have undone it by hand if I'd done that first.

I have a 5ft length of heave steel pipe for this very reason. Leverage.
It came in very handy when trying to undo the crank bolt of a 4.4L V8 Beemer engine. The rear opposite corner wheen actually hopped off the ground before the nut gave in. The owners forums nickname this nut as "The Jesus Nut".

Hi All

Thanks for all your advice, and yes, I guessed the sledgehammer quote was a joke!
I’m going to bite the bullet and take it to a shop as I’m going to break something on the bike with the amount of force/leverage I’m putting through it.

Last bit of advise if I may; I’ve gone to put the sprocket cover back on and now I’ve got no clutch lever, so I removed again and there isn’t anything to tension the clutch cable. Is there supposed to be a return spring or something in there?

It’s bad enough that I’m having to pay someone to undo a bolt but now I can’t even get the bike to the bloomin shop!!!

Is it a yamaha? They have the clutch cable on the near side and a pushrod through the engine to the clutch.

You need to ensure you align the cover with the pushrod before you put it on.

Does the clutch cable dgo to the top of the casing you've just removed? If it does you need to ensure the clutch cable mechanism is correctly connected to the pull rod before you bolt the cover back on.

Would depend on the size of bike, but get a breaker bar or i use an old torque wrench (24 inch), something around this size with an extension going into the engine bay to allow some room, put it in gear, put your foot on the rear brake and try to also hold down the front brake, and or do this with the front wheel against something to stop it moving forward. If you have help great but if not, you'll use your left arm to un-do the nut, it's never failed for me....

If it's not playing ball it's either been over torqued or someone used too much loctite....

look out for a locking bolt (not the actual sprocket nut), or a locking washer that's been bent into the nut, this needs to be levered back to allow the nut to turn.

consider buying something if you don't have it, as you'll use it time and time again!! order online if no where open!!

Well this thread made me think about if I need a impact gun , battery type.
Wow! They’re bloody expensive .
I think I’ll stick to six sided sockets and a long extension bar.

Unless someone can recommend a reasonably priced battery powered impact gun??

EDIT : they’re a lot cheaper on thief-bay.

Mine just undid the nut that holds on the rear wheel of my sprint. I know it was done up to 165nm ( as per the manual) and the wheel didn't spin despite being in the air.

Ryobi... it basically just coughs in the general direction of nuts and bolts and they undo
