B5 yanmar mini excavator boom cylinder

[JRA29]

I am needing to remove the boom cylinder from a b5 yanmar, and im having trouble knocking the pin out, its the pin under the floor board i have remove 2 bolts that held a piece of steel that held the pin in place. I cannot get it to budge, i have placed a long bar through the access hole around the fuel tank to try to drive it back toward the seat. Any suggestion will be greatly appreciated.

it may have a groove worn in it, you may need to tie something to the cylinder and pull it up and down some to maybe let it move around some so it can come out. I have seen them worn half in two or better. Maybe it is seized on the ends and a little heat could help it budge loose. If you can wiggle the cylinder on the pin, it may be worn like I said. If it feels tight, maybe just the ends are seized and won't let it move. I have a torch that is straight and not L shaped and makes it easier to get into places like that. Hope I helped.

I was needing to repack the cylinder ill think I will attempt it on the machine.
I just wondered if some else was holding that pin in
