Twist my nut

[Benjiboi]

I need to loosen a nut on my FXR150 so I can re-adjust the chain, but the problem is that the hexagon shape has some rounded corners and is started to look rounded.
What is the tool to use, it is on there fairly tight??
Also what is the ideal slack for a chain??
The manual says 10-20mm does that sound correct.:

A ring spanner would be closest.
Yes 10-20mm.

Use a well fitted socket wrench that hopefully has minimal movement around the bolt. Depends how tight it got put on haha but yeah it's probably fairly tight. Yeah I think slack from its highest to lowest point halfway between sprockets should be between 1-2 inches.

Thanks I won't be fumbling in the dark now lol

I believe 6 sided socket would probably be a better fit than 12 sided, but if its already rounded who knows. That or the exact spanner as mentioned. Cresents will round it out quick smart

Get a 6 sided that fits good, if that fails, you may get away with finding an imperial thats slightly smaller and wacking it on then out with the man bar to try and loosen it off. I've gotten away with it in the past. Then replace the nut with something thats not had it...

A no slip socket works wonders in cases like this

If it's really bad you may need a pipe wrench, make sure you have a new one to replace with.
10mm seems pretty tight.

Plumbers call them "nut-fuckers" because they, quite simply, fuck nuts.

6 sided will be an impact socket which you can normally buy as singles from any good engineering supply store.
Even if the corners of the nut are well rounded off,the flats will still pick up on each other.



The TL1000 has a hex front axle with clipped corners that a 6 sided 27mm socket works best on.

Centre socket above is a flank-drive socket. It is practically impossible to round off nut or bolts with them. Instead of pushing on the edges of the hex the force is applied on the flats. Snap-On were the first with them I think.

If you need you can drop by home and I can loosen it with the rattle gun or a ring spanner and a mallet. PM me if needed.

Just a quick round trip from CHCH

Yup, snapon make a good socket, bloody expensive but.
Another good option are the Metrinch ones. They also use the flank drive system, but are designed as a looser fit, so the one socket or spanner will work on both metric and imperial stuff.

Remember to use WD40 or CRC spray a few days before you attack it with the spanners.

Usually I'd say that wheel nuts undone for chain adjustment are easy to remove but since this is a learner bike, who knows? Get a new nut, clean up the axle bolt threads and you should be sorted.

6 sided will be an impact socket...

Most decent brands also do single hex sockets in non-impact (I have all sizes under 14mm as single and double hex in Koken). This can be important when you have no clearance for the thick wall of an impact socket.

I've taken the nut off today with a ring spanner, turns out it wasn't that hard.
But since i'm new with bikes and whatnot it seemed like a bigger deal at first.

Anyway thanks for all the posts definately very helpful
