Removing lower shock bolt--heat needed?

Changing out my shocks for Ohlins on my 2010 R12GS, 34K miles and they are TOAST. The Reprom calls for 212F heat to remove the swingarm shock bolt. Just how the hell are you supposed to heat that swingarm up without blistering the crap out of the paint--and maybe roasting some other components close by? I have a heat gun but if anyone has any experience and/or tricks for this, I'd appreciate you letting me know. TIA!

I've taken this bolt out with no heat on 2 new GS's with no issues. I recall the lower bolt on the front was a bit tight once and needed some heat.

Thanks quirky, maybe I'll just try it without the heat then. On my '07 RT I almost ruined the bolt head it was so damn tight. Didn't want a repeat of THAT! Maybe their shops have complained also, as heating it takes more time and can be risky.

But if anyone else has had to use heat, please chime in.

You may or may not need it, but I would use heat just to make sure you do not gall the threads. Heat it until the bolt sizzles spit.

Jim, apparently you have done this before---how did you heat the swingarm up without blistering the paint or worse? Any tricks?

Soldering iron

If you have a heavy duty soldering iron you can try to heat it the bolt by itself.

I do have one--thanks Felipe--I will try that first. Dunno if the heat will make it thru to the threaded area of the bolt but its worth a try.

Edit: took a look, I think there will be too much "heat sink effect" for the heat to make it all the way to the threads. But I'll try it and see.

I usually use a heat gun. You can get one for $10 from Harbor Freight. No chance of damage like that.

Some also use a map gas torch, but you have to be more careful with it.

Look at it from the other side, and see if you can touch with the soldering iron the threaded side first.

A little heat properly applied will make things easier.

Didn't know the other end was exposed--I'll take a look.

I doubt the threads are visible. Use a heat gun and you'll be fine ;)

There is no access from the other side on an R1200.

My heat gun is old, has only one temp--hot as hell. I think you could weld with it, lol. I'll pick up a cheap H-F 2-temp unit and use the low 500F setting. Just trying to avoid paint blistering and other unwanted effects. Like melting my rear fender extender.

used a $10.00 HF heat gun...

I ride an R1100RT and used a $10.00 HF heat gun on the HIGH setting (carefully) and had no problems with paint blistering... just focus the heat on the exposed portion of the bolt... an infrared thermometer to gauge how hot you are getting it might also be helpful, although I didn't need one...
