Title: Stuck pro neck 2
Post by: Hmoon27 on July 05, 2012, 09:11 PM: Brought a bike of eBay (survivor) with a pro neck 2 stem on it and tange arx forks.

Stripped the whole bike , came to the stem and it just won't budge! Got the bolt undone and wedge is nice and loose , gave it a good spray with wd and left overnight, but no joy.
I've just turned it upside down ,taped up the hole on the stem and tied a rag around it so no fluid escapes , I've then completely filled the fork tube with 3 in one penetrant spray to see if this helps.
Don't really want to put the forks in a vice and give it a twist as I don't want to risk bending the forks?
Or am I missing a trick with the large bolt on the stem, what does this actually do? :idiot2:
What'd ya reckon boys?

Plus-gas the outside of the stem shaft ie inside the forks and then grab the top of the forks in the vice at the brake hole and plenty of rags, put the bars back in and give it a twist :daumenhoch:

Post by: Hmoon27 on July 05, 2012, 09:59 PM: That was my next move spen :daumenhoch:
I also took the bolt right out so the wedge fell out the bottom of the forks , but to no avail >:( thought if I could get the wedge out, I could try knocking the stem out from below?
