Stuck nuts?

[007brendan]

I'm trying to remove my swingarm and the linkage connected to the rear shock but one of the nuts is on there super tight.  I tried blasting it with wd40 but it didnt' help.  I'm starting to round the edges.  How do you remove these suckers!!??

Should I use an impact driver?  There's a bunch at home depot in the $80-90 range, but they're all 1/4 inch bits and look to be designed for screws.  Will they work to unstick something like this?

Look for an impact driver at an auto parts store - they are usually closer to $20.

Can you try heating up the area with a torch? The heat will ruin some stuff, so I don't know what you're planning on replacing.....

How about PB Blaster? Spray it on and it'll eat through any rust/thread lock. You may need a couple of applications.

If you have a hollow steel tube, you can slap that on the end of your wrench to give yourself some more torque.

Or save the headache and grab an impact driver. It's not like you'll never use it again.

If you do end up rounding the nut, I would recommend turbo sockets. They're reverse threaded and eat into the nut, and they'll pull it right off.

Edit: These be the sockets I was talking about:

Thanks, I'll check it out.

I'm replacing sprockets and chain, so I had to pull the wheel.  Since I was pulling the wheel, I figured I'd replace the rear shock with a gsxr750 shock I had.  And as long as I was replacing the shock, I figured I might as well pull off the swingarm and linkage to check the bearings and lubricate them.  You know how it goes...

An impact driver for sure.
The purpose made socket is probably going to be some silly price but maybe u can make your own up(depends on what bits u get with the driver)

Yes an impact driver if you can't have access to a rattle gun, of if you have the space to put the ring of the appropriate spanner on the nut, then put the ring of the next size up in the open end of the spanner to give you extra leverage. Of course after spraying you favorite penetrating oil or freeze n release.

If you happen to have a chisel and ball pean hammer handy that will work as well.

Just make sure it's a cold steel chisel not a wood chisel...lol

Bluehaze had rounded the nut on his linkage, I tried Vice Grips, but anything tight enough to get a grip also collapsed the soft nut, seizing it to the bolt. In the end I had to use a cut-off wheel on a hand held die grinder.

I ended up getting an impact wrench, advertised as being able to deliver 200 ft-lbs, which came in handy for some of the other bolts, but did absolutely nothing for the linkage bolt.  The thing was totally seized.  I resorted to grinding it down with a dremel and a hand file, and then hammering it off with a chisel.

Hammer and chisel works good, but sometimes space constraints are a problem. Also you ruin the nut.

You animal....I saved the bolt, it didn't have one grind mark on the threads, we just had to make a trip to the hardware store for a new nut.
