Title: FJ pickup rotor bolt...can't undo
Post by: mr blackstock on February 07, 2016, 06:29:30 AM
Hello all,
I am in the throes of changing over pickup plates, and I am having a bugger of a time getting the bolt out, the 14mm one holding the pickup plate in place.  I bought a manual impact driver, belted the hell out of it to no effect!

Is it a reverse thread? I looked in the manual and it did not state so...
What have others done to remove this bloody bolt?

Much help appreciated,
Cheers, Gareth

How are you keeping the engine from turning? A manual impact driver turns very little during impact. So if the motor can turn even slightly, the driver is turning the engine and not giving the bolt the rotary impact that is intended. I used a breaker bar (longer handle/lever).

G'day,
I have a breaker bar, but it is stopping the engine from turning that is the sticky point, I can put a piece of wood through the back wheel to stop the rotor turning, but something just does not feel right about doing that.  Putting it in 1st gear will not hold it enough...

Does the bolt undo anti-clockwise like I suspect?

cheers, Gareth

A piece of wood wrapped by carpet or rags is standard for keeping the engine from turning, that is what I did. The chain is more than strong enough. I don't remember if the threads are LH, I don't think they are. That bolt is a common issue for many to remove the first time.

I know Your pain.....  :sarcastic:

It was impossible to unscrew it on cold engine. But after short trip to shop and back, when engine was warm not hot, screw gave up after 2 seconds......

It is a standard right hand thread. 
A pneumatic impact driver had difficulty loosening mine.
A hand impact is going to be difficult.  As suggested, try warming it up first, either by riding it or using a hot air gun.

A rattle gun should undo it easy enough, holding it still to torque it up is harder so I made this little bracket to hold the rotor, worked a treat either undoing it or tightening up.

G'day,
Thanks everyone for the good tips, I will heat it up and make a bracket, hopefully that will help.
Nice idea "Bones"

I will try it today,

G'day,
Well I made up a "plate" to stop the rotor turning, it looks a bit industrial and hard core, but as well as using a hair drier to warm it up, it worked a treat!  Thanks again for the tips guys.

Cheers, Gareth
