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 :yes:

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

[nodrog]

Turn them to the left.

All sound advice.

That WD40 advert from 1957 could be misconstrued for present day S & M advice :msn-wink:

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.

he never mentioned there were any nuts......

[mossy1200]

Some BMWs have bolts going all the way through with a nut at the other side. Not sure its a very common system.

Not on the non krautscycles

Giving the head of the bolt a sharp taps helps too. Impact effect

You can also shout BOO when you're undoing them. Spook effect :wacko:

They might also turn turtle esp if you use the freeze spray.

Laugh but it works it the impact frees the threads.

Oh I'm not laughing. In the past I've employed all manner of ways to free seized or thread locked bolts. A tap with a hammer works wonders. A spray with CRC or WD40, if one can get the stuff into the right place, is tried and true. Simple dunking in hot water also has worked in the past. Bit hard to get a wheel into the bathtub though I'd venture...

[george formby]

The amount of heat I applied could be achieved by holding your tongue on the bolt. A hair dryer would be easier.

Bugger, I took the bolts out of a Honda. Could have given myself a wee primp at the same time.

A bit of warmy coolly tappy tap tap sounds the go.

Esp if the misses is home.
Bad enough getting parts into the oven and dishwasher

Yeah, once, my missus walked in with one of her girlfriends when I had my leather suit spread out on the lounge floor. On top of a few towels spread out, using her hairdryer to work the dubbin/beeswax into the suit...if looks could kill :laugh:

Kinda makes a few stuck rotor bolts seem like a piece of weez...

[Hawkeye]

Tried the heat but still no luck. Probably because my heat gun packed in after 15 secs :Oops::cry:. So it's off to Bunnings to get a replacement tonight. Tried the hair dryer but that only got me grief. Her who must be obeyed wasn't too happy about me having her brand new blowwie thing in the garage:bash:

No nut, just bolt with hex key.

Blowie in the garage. A good start to the night but won't do much for your rotors.

I pay (qualified) people to do jobs I find difficult.

It's worked so far ..

[Hawkeye]

Heat and rattle gun did the trick. Red Loctight on the threads as surmised.

You must have a mate ... that would do her for free .. <_<

Sooooo, pay a lot of people then I am thinking, do you? :bleh:

I heard some retards get special rates, do you have a card or something. :msn-wink:

Think I saw you in that movie "Top of the lake" But you had a scottish accent and you had gotten you daughter pregnant.:devil2::shutup:

That wasn't me ... and it was the neigbours daughter .. :innocent:
