Mini Excavator Pulling Teeth

[whatsupdoc]

I need to replace all the bucket teeth (5) and one tooth adapter. The teeth are
held by a roll pin installed top to bottom. I managed to remove one pin
without issue but the rest are frozen. I tried some heat and a 3lb hammer but it did not seem to help.

I stopped before I mashed them, so any tricks ?

Do you have the correct size punch? Also are they tapered or straight? Penetratung oil, heat, cooling and persistence with the correct size punch wins the day. I learned all about this removing a PTO knuckle this winter thanks to the folks on this forum. Good luck.

If you give better details you might get better answers.
Like make and model, and pictures.

There are lots of utoob vids dealing with this subject too.

Its a Yanmar Vio35, image is the bottom of the bucket.
I cut out and welded on a new tooth adapter (right side in the pic)
and replaced two other teeth but two remain.
The crazy thing is both moved, one moved at least 3/8" and the other
maybe 1/8". Heat and beat numerous times but no joy.

I used the machine today so that is why its dirty but it was clean when I
went to drive the pins out.
