Got mah trusty 12-ton floor press. On one side it came out after an ungodly amount of persuasion, the other seems it likes it there and refuses to move. I figured I would ask before just letting the press go at it full force.
These came out of a sandrail I'm redoing. Chances are they have never been serviced. The links themselves were extremely worn with pretty much oval holes.
On a related note, is there a fairly priced 18mm reamer out there suitable for this job? For what I recall the correct reamer has the cutting are towards the middle of the reamer so it can align itself between the top and bottom. I see inexpensive 18mm reamers but the cutters are at the end. I was planning on taking these to the shop to have them reamed but if I can find a reamer close enough to what that would cost me... |

| An automotive machine shop with a wrist pin hone/rod machine should be able to ream them at minimal cost. |

Here in Alaska everything seems to be more expensive so I'm hoping it is. Meaning it will give me an excuse to buy yet another tool 
It finally came out. What was funny is that it took about 4 tries: It would CA-CLUNK! loudly, move a quarter inch or so, and get stuck again. Oh the joys of working with ancient neglected stuff  |

Ive had to boil the tough ones in a pot of hot oil. I think the manual has the recommended temp. Evenly expanding the carrier and letting oil get into the pin really helps in removal.
Carcraft had a a cheap reamer for this, I picked up some core spindles/carriers and rebuilt and sold them to pay for the reamer plus a bit extra

Yes, heat the spindle, and let the heat draw some oil in.
And you need a dedicated reamer that can pilot off the other king pin bushing. If you mess it up then you did all the work for nothing.
