MaxK Posted March 14, 2024 Posted March 14, 2024 Anyone got a clue how to remove this nut(?) Just keeps spinning, hoping no one tells me its on a left hand thread bolt Its a 2018 Honda CB125R Â Quote
Fiddlesticks Posted March 14, 2024 Posted March 14, 2024 Is there a nut on the inside you can get to with a spanner? Quote
RideWithStyles Posted March 14, 2024 Posted March 14, 2024 if not then you may have to do some proper repair or replacing to do. unfortunately the bolt screws into the swing arm... if thats spinning you might have to take the other side bolt off and hold the nut/push the bolt out from the inside... just use the centre stand and support the bike, remove the wheel as your pretty much gonna have to no back end. worse case you're gonna have to replace the swing arm unless your really handy with a welder/drill and tap.

husoi Posted March 15, 2024 Posted March 15, 2024 If that is the bolt that holds the swing arm you will have a nut on the opposite side. It should be a normal thread because isn't a moving part. Use a 6 side socket not a star one or you risk damaging the bolt before it moves. with the socket in place (ideally a old one) hit it a few times with a hammer to break the lock. The same way you would with a screw. As extreme, you would remove all plastic, protect the inside of the bike and heat it up with a torch (the thread side not the bolt). 1 Quote
Capt Sisko Posted March 15, 2024 Posted March 15, 2024 (edited) As Husoi said and confirmed on the page below that 'nut' is actually the blunt end of the swinging arm pivot and once the other end is undone it should, in theory, just slide out. I say in theory as 1. By the very nature of it, it's got to be a tight sliding fit, and 2. The odds are after six years it's very likely some corrosion has got in and the buggers seized up.  Unless it's seized solid and is going to need heat / a Hydraulics press to free it, it's all perfectly doable at home and not that complicated a job; but be prepared to curse, swear and bang your knuckles doing it. https://www.bike-parts-honda.com/honda-motorcycle/125-MOTO/CBF/2018/CBF125NAJ/Frame/SWINGARM--CHAIN-CASE/100048/F_32/2/32221   Edited March 15, 2024 by Capt Sisko 1 Quote
