This illustration from my mini-excavator parts book shows how the flag pin is supposed to hold the pin from rotating so all movement is between the pin and bushing. Looks like when your pin seized in the bushings it really wallowed out the holes. You have your work cut out for you building that back up.

Thanks for that, most informative.
I'll look forward to cutting , grindong , drilling , swearing etc but I suppose it has to be done, but after we dig the drainage trench

ONLY GONE AN DONE IT..............WAHOOO.:thumbsup::thumbsup:
Found a piece of solid bar just smaller that the pin and cut a piece off about 3" long
Brother Edd held this over the pin with a pair of tongues whilst brother John whacked it with a sledge hammer.
Second strike it started to move and we were able to drift the pin out.
The pin is very worn at either end but perfect in the middle so we cleaned it and put some grease in via a new nipple and it squirted out the hole in the centre. The grooves in the pin for the gease to follow are perfect so here's what we intend to do....
We ground the flag off the end for re-use and are going to put a sleeve over each end the same size as the holes in the outer arm to take up the wear. Then reamer out the holes in the outer arm to the same size as the sleeves.
refit the pin and weld the flag back on so as we can secure it and hey presto good as new at very little cost (bits from under the bench)
Sorted:thumbsup:

Glad you were successful! It didn't sound like it was as difficult as we were all predicting.

Sutol, I call my sledgehammer a special adjusting tool for making precise adjustments.

This picture looks as if the head of the pin was welded to the arm
