So my 11yr old grandson is visiting, we are taking a engine apart for fun.  He is learning how to use wrenches and socket and we are having a great time.  However, this old chicago rusty engine now has me at a standtill, I don't want to bore him so I think he as seen enough of removing stuck fasteners and so the rest of the disassembly need to go smoothly.

I can't seem to remove the distributor, I've soaked the joints, and hammered it, but it's not coming out. 

Am I doing something wrong? 

The ear on the distributor for the bolt is broken off, the aluminum distributor is also now broken off from my pounding and I the outer hollow shaft and the rotating spring advance assembly are all that's left.  No force seems to make the outer portion move.  

No hammering on aluminum cast parts.  Oil pump, distributor, big no, or expect it to break.

#1 thing I have found to help disassemble these engines without breaking bolts, etc. - Heat the entire thing to 160-190 degrees F.   Easiest to do if it is still running, but a space heater and a heat gun will do it also.  About 2KW of heaters did it for me.

#2 thing, Kano Aerokroil or similar penetrant.

#3 patience!  Carefully turn bolts, etc.  feeling if the bolt is turning, or twisting off.  After years of experience, I can usually tell.  Once a bolt starts to move, if it starts to get stiffer again, stop, turn the other way, then go back to loosening, until it sticks.  Repeat many times.

 

I hope you’ve got a replacement distributor ready to go. I believe they’re also annoy so easy part to find these days. 

Cheers
