Earles Fork Steering Stem removal?
Been a while since I've been on proper after getting my R90/6 all sorted and many happy miles. Now I'm starting a new project to do a close as I can RS54 Rennsport replica with my R75/6 I picked up. Don't worry, it needed a full rebuild anyway!
Big question, can I heat the cast iron lower triple of an Earles Fork to remove the original stem with a puller? The original stem is twisted/bent out enough at the steering lock to stop the bearing from slipping past and it would just be so much easier for me to machine a new one. Probably out of stainless. I will post pictures later.
What do you think? Anyone with experience in this swap?

Probably yours is much worse than mine, as I'm planning to use a file on the damage and call it good.
'hope to see more of this project of yours.

I have pressed these out before, several times. If there is damage at the steering lock channel, you need to deal with that before you can press it out. If you aren't going to reuse the stem, take all the measurements you need then cut it off just above the lower bearing surface and just press it out cold.
I deal with the steering lock channel by slowly tapping in the damage with a hammer without getting carried away in any one spot. Cracks can be ground out and welded, finishing out with some decent file work. Keep working the damage at the channel until you can easily slide an old steering head bearing past.
These steering head channels get so badly damaged by trying to force the steering lock, trying to brake it. There is some miss-information going around the web stating the steering lock can be broken by forcing the forks to turn past the lock, this is false! By forcing the steering with the lock engaged causes damage to the steering stem and makes the lock removal even more complicated.
