Rounded sprocket nut

Evening all,

Me again - my weekend project has now resulted in lots of swearing and frustration.

Started inspectting the rear sprocket today as my new chain and sprockets are arriving tomorrow. I have noticed that one of the sprocket bolts are completley rounded. I have cleaned the area up; the rest of the nuts are not looking great so I am going to replace them all. Can anyone suggest the best way of getting this off? Would rather not remove the rear wheel if I can help - I was thinking of either a grip & twist socet or a nut splitter (ebay) unless anyone can offer some assistance?

 

If its that rounded, perhaps it didnt get vey tight. Maybe some fresh vise grips will get it to move. Or setting a chisel and then vectoring lefty-loosy.

But maybe a grip n twist socket should be tried first before potentially mangling it.

 

Is this a Fifth gen? Wait until your new chain and nuts get in before playing with it. Remove the old chain to get it out of the way.

Captain 80s suggestions for vise grip or twist and grip sockets is the way... Just know, you'll need to put a 5 or 6mm (can't remember which) hex key in the head of the stud on the backside of the sprocket to keep the stud stationary. Those studs are actually hex key cap bolts.

You'll need the hex key back in there when you go to torque the new nuts as well. I think they're around 20 ftlbs

 

Thanks both for your replies - have managed to get this free and off now. Started with the vise grips, then managed to get a 13mm socket over the nut (with the aid of a hammer but gentle tapping as worried about the bearings, if that makes sense). Managed to get the nut loose so I know it will come off

Going to replace all of the nuts/bolts as they are looking worn and tired - if anyone has any recommendations please let me know

 

For something as important as sprocket hardware, I'd go with Honda OEM parts. If this is a fifth gen, those part numbers can be found on the Rear Wheel parts drawing.

 

leaving the old chain in position makes it useful to thread the new chain in so you don't need to remove the front sprocket cover [and deal with the horrible filth therein].

i recommend you keep the new chain oiled properly so it doesn't look rusted like the old one.

i apply oil with a paintbrush and push the bike forward to get all the chain covered.

 

^ its just plain wrong to "Chain Shame" someone despite being across the "Pond". You could always get a Scott Oiler that will solve the rust problem. I used to ride through the winters of NJ with salt and crap and never had a rusty chain, (no shaming) my bike was garage kept though. Sucked to drag the water hose out on really cold days. I like a chisel and hammer for some stubborn things (people) or some MAP gas, just be careful around petrol and plastic. Good job getting that nut off!

I agree 100% (the chain is not in a great state) - which is why I am stripping the bike down - it has covered hardly any mileage over the last two years and is a project for me to restore. There is a scotoiler on the bike, but like the rest of the bike is all gunked up and in a bit of a mess.

New chain, sprockets, spark plugs, air filter etc. all arriving this week so will hopefully have everything stripped down and cleaned up.

I'm not a big "product" fan, but Maxima chain clean and lube (not wax) are unbelievably good.
