Hydraulic cylinder leak on JCB 1400B backhoe

What is the easiest method to pull this cylider out? Should I dig a hole as deep as possible, put the boom down in it as far as it will go down so I can pull the cylider straight up and out with a cherry picker or are their better methods?

What do you think the cost will be to get this cylinder repacked or rebuilt?

I attached a weblink of some pics of my hoe for your viewing pleasure :)

Thanks much for any advice!

My land is very rocky (I am talking boulders) and the places I tried to dig were just too rocky so I decided to back up to edge of a hill and extend the hoe as far down as it would go (I did have to move a few rocks out of the way to accomplish) This made it a little more challenging to work on but worked out fine.

I must say it was quite a chore removing the cylinder as the pin that mounts the lower part of the cylinder to the frame do not want to move, I must have beat on it for 2-3 hours with an 8lb sledge and it finally gave but destroyed the bushing in the process (after I got the pin out I ground down the one side some to make it easier to reinstall) the upper pin the mounted the piston to the boom slid out easily.

I used a cherry pick strapped into the back of my pickup to remove and reinstall it, this worked well as it made the cherry picker more mobile and also increased the lift height

The cost to rebuild and rechrome was about $450 not sure if I could have bought a new one for a little $$ more but I shouldn't have anymore trouble with it for a while.

So I am back in business, thanks for your advice folks!
