My new build arrived today
The stem Allen bolt is fooked, rounded out & rusted to Fook
Need it off as to get the forks off
Any tips :-\
Lee :idiot2:
-
Drill (better if you know someone with a pillar drill)
A steady hand
and a rubber hammer :daumenhoch:
Oh and WD40
-
If it protrudes from the stem, an external stud extractor would do the job.
-
The bolt is not protruding
Just tried drilling with no impact what so ever
:idiot2: :'( >:D :2gunsfiring_v1: :2gunsfiring_v1:

Get a hold of some spline bits.
The one for VW driveshafts is just a fraction bigger than a 6mm allen key - you should be able to get this spline bit at a good car accessory shop.
Get this VW driveshaft spline bit, and hammer it into the the allen bolt.
Also before you do it, pour a kettle of boiling water over it - the heat may help you out.

put up a picture of the offending bolt so we can see what we are dealing with.

Desperate times calls for desperate measures
Hack sawed the Cnut off >:D
Wanted to keep the forks as now the remainder of the stem & wedge etc is stuck firm
Lee ;)
-
So the bolt didn't protrude, but you managed to hacksaw it off?
Or - you hacksawed through the stem?????
-
Through the stem, pics to follow
-
Bet that stem took some sawage!
Is there a bunch of stem junk stuck in the fork's steerer tube now?
-
Gonna be hard to get the rest out now :(

This is what I'm left with on the forks

If anyone knows or can get the remainder of the stem out for me
I would be eternally grateful
Would like to keep the forks original to the frame
Or should I just get another set
Lee :D

What stem was it ?
-
Hammer the shit out of it from underneath.
Be sure that the drift you use fits nicely in the steerer tube.
Maybe give it a tap at the top too, to break the seal.
I wish you had tried my spline tool method in the allen bolt. You could have used the stem itself to shift the shaft!
But you could start by whacking the bolt itself - maybe push the wedge bit down and free off the steerer tube.
Good luck . . . !

Just some cheapo shoite thing
-
big hammer and smash it to fook :daumenhoch:
-
Or just let the Man Mountain Dordy ::) growl at it and the fooker will fall apart :shocked:

Wrap some insulating tape round the threads to protect them a bit.
Hammer the fook out of what's left of the stem wedge downwards, if it drops down drill a hole through the shaft, put a bolt in it, hold shaft in vice, bar through forks and turn.
