Removing front rotor bolts?

[Hawkeye]

I'm renewing the front rotor on the bike but can't get the bolts out. I've tried a torque wrench and also a rattle gun but neither of these will budge the bolts.
Reading the manual, they also suggest replacing the bolts and that the bolts come already coated in a loc tight coating.
So I'm presuming the originals also had a loc tight coating. Bolts have been in 17 years so well and truely seized.

So any suggestions on the best way to get these loose without stripping the bolts or completely buggering the wheel.

I recently managed to remove some impervious bolts with fossilised loctite by warming them. Gentle application of a heat gun. Said heat softens the loctite. Apparently.

No idea how you would romove them, though. Might need a gym instructor.

Heat was option 3 but thought I would just check in here first before resorting to blow tourching the wheel.

Try a hot air gun first. Another thing I've seen find was use a soldering iron on the bolt head for a while... Just don't touch the bolt after. Heat is the best thing to get loctite off.

He's not saying blowtorch the wheel - use a heat gun. Somewhere around 60 -80 deg C is usually enough to expand the alloy enough to make movement possible - well below what will damage the coating on the wheel.

Hi Grumph. That's what I meant. Got a paint stripper gun so can control the heat

I have a gas soldering iron with removable tip and 18volt dewalt impact driver if you want to bring around.

Turn them to the left.

All sound advice.

That WD40 advert from 1957 could be misconstrued for present day S & M advice

If heat is applied ... heat the nut. NOT the bolt.

Heat makes things expand ... make the nut bigger and NOT both.

As said ... replace parts removed with new. (peace of mind ... and all that)

I have read about freeze in a can. By all accounts the bizz

Not necessary correct FJ.
Heat also weakens chemical bonds like rust and electrolysis and also weakens Loctite.
Cycles of heat to cause expansion and contraction help free stuck fasteners.

PS the rotors are likely held only by bolts.

+1

Heating the bolt to expand everything and they contract as they cool at different rates will destroy the loctites bond.

You could also try heating the whole lot then hitting the bolt with freeze spray; though I expect just normal heat plus rattle gun will suss it right out.
