m35 hh socket size

[m715]

I got my m109 home, What is the best way to remove the center bolt in the hyd head. Do I use a thin wall deep socket and what size? I have no fuel to injectors and have checked fuel shut off. I want to see if plunger is stuck. Thanks mark.

I think its 7/8, i usually use a 10inch extension 3/8 drive to clear the injector lines.

Thanks,I got the bolt out. I put some b12 cleaner in the hole and let set for a hour. I put a wood rod in and watched it go up and down and spin as I pushed the starter. I am now getting fuel to as least one injector now. My batteries got week so I stopped for today. I need to get set up for deer hunting Monday so this truck will have to wait. thanks for your help.
