Hydraulic Breaker Repair

Ive got a Bobcat model 2500 breaker that i picked up from a friend, he wants me to keep it since i will use it 2 times a month vs his 1 time every year.

the trouble is the diaphragms need to be replaced. i have pulled the front and rear diaphragms, but am having a heck of a time trying to pull the bolt on the top of the breaker.

Has anyone gone through this before? maybe tips on what worked well to pull that bolt loose.

ive soaked in PB blast, tried 6' cheater bars, 1" impact, i thought of using a 48" pipe wrench and somehow utilizing the hydraulic power of the CTL to break it loose (chain wrench to tree or something)

If i can get this thing running for a few hundred bucks it sure will be handy to keep around.
If you do what you've always done, you'll get what you've always got.

It will take major force to break it loose, you might need to secure the hammer to a concrete wall and drive over the wrench extension with a skid steer or something, my Dad's hammer is getting rebuilt, and the person who did it before put over 800 pounds of torque on the 4 bolts that hold the hammer together.
The amount of energy necessary to refute bullsh*t is an order of magnitude bigger than to produce it

Try a porta power, we break steam turbine bolts that get torqued to 1000ft/lbs.
Alot of times we heat them cherry red first.
