Another pivot pin removal question

[Donnyviking]

Acquired a used T250. Pivot pins are shot. The nut and bolt both turn, so I need to remove the plate with the zerk fitting to hold the bolt head, however I can't get the plate off. Service manual says use grease pressure, but that doesn't work since the grease just flows through. I tried air pressure through zerk hole with same results. I also tried a 1/8" NPT pipe into zerk hole to pry, but this didn't work either. It's hard to believe an O ring could hold the plate that tight. I really didn't want to use torch with the grease present. Any other creative thoughts on removing this damn plate?

Make an adapter for a slide hammer. I welded a zerk at an angle into a nut and then welded the correct thread nut for my slide hammer. I welded the zerk at an angle for clearance as my slide hammer to to long to fit between the arms. 99% of the time the threads in the cap are strong enough to pop it out. Dumb question, you did remove the snap ring holding the cap?

If you don't have a slide hammer like I did when I did my s250 I made a little puller out of a 1/8" pipe nipple, 3/8 bolt and nut and piece of 3/4 angle iron. It popped them out pretty slick. I drilled a hole in the angle iron, put the bolt through the hole with the nut on it already. Stuck the 1/8 nipple on the end of the bolt and welded it there. Then just thread the nipple into the hole, tighten the nut up and it will pull it out. I would take a pic for you but I am away from home.

Thanks for the information. Yes snap ring was removed. I tried the slide hammer idea. I used brass NPT which was stupid on my part. Broke fitting so drilled out and tapped to 1/2-13 than ran long bolt thru hole. Kept turning bolt until plug was out. Scarred the side of the plate and bore. Lots of dirt in grease. I need to put a plug into the plate to get 1/8 NPT again or just change to a standard thread zerk fitting. Thanks again for the help.

When i had one that would keep turning, i had a helper on the end of the spanner on the arm and i pushed the machine into a tree, providing friction to allow the bolt to be un-done or done up.
No reason why you can't go for a bigger grease nipple thread.
