Stuck dowel pins in transmission

(1/4) > >>

Hey, it's me, back with another episode of things that are unbearable stuck in my motor. This time, we are talking about dowel pins. Specifically the two outlined in the picture. This is the last thing I need to get out before I can start cleaning this engine, and of course this is giving me problems.

They are soaked in WD40 right now, but I am scared of using pliers on the one, because I will probably nick the bearing part. And the other one holding the transmission fork is not moving at all, in spite of me using a telescope magnet the best I've learned.

Selector try wigglihg selector with magnet attached, they usually fall out.
Casing dosnt HAVE to come out to cleam but look for it every time you move case in case it falls out!

Wiggled with the best of them. Damn thing haven't even budged. I guess I could clean the engine still though. And also paint it, as no paint is coming near that assembly. But this is starting to become a matter of pride. Every damn thing has to go out of this engine, if it becomes the end of me!

Which it probably will… :)

McCabe-Thiele (Ted):
One of my dowel pins did not fall out easily on my 400 as I could get new replacements easily I used a pair of pliers to extract one - It seemed to be held in by oil underneath it that acted like a suction glue effect.

I would soak with a  bespoke  releasing fluid like Plus Gas Formula A overnight rather than standard WD40 then try to rotate the one you can grip - mine came out with a magnet after rotating slightly.

Heat the casing gently below the pin. As the oil expands it will push the pin out.
