Pushing rather than hammering makes me more comfortable to attempt greasing the bearings, I see no other option for me and that vintage folding bike I got... I'll see if I'll remember to report back with the results, I have quite a selection of C-clamps!
@@ReferenceBicycle I just tried with a massive clamp I have; no budging, the clamp started bending, it would have snapped a dedicated tool in half. The pin doesn't even look that rusted, but no amount of clamping, torch heating, and pounding achieved anything! I'll just leave it be and throw away the whole bike when the bearings will fail :(
I can honestly say I have never seen that happen before. I would try a 3-jaw gear puller. You can get them at Harbor Freight or Amazon. The spindle to arm bore is typically a slip fit, so I’m surprised it won’t release, unless it’s extremely corroded or somehow got deformed. No guarantees, but I would give it a long soak with Sea Foam Deep Creep then try a gear puller. Let me know how it goes.
Yeah, it’s not ideal. I haven’t done that method in probably 20 years, but it doesn’t stay centered on the cotter. You really need two sets of hands (3 if you are trying to use a bench vise). The Park and Bikesmith tools self center and make it a one-person job.

Yes, the C-clamp method works fine. It’s just more cumbersome than using the BikesmithDesign tool. Good luck! 🍀

But how do we get the crank arm off it it's stuck? Got the pins out but the arm is stuck on

Interesting. I’m willing to wager that a c clamp for this job would result in a lot of swearing.
