Zerk fitting replacement?

I made a device one time to break fittings free.
I had a small hydraulic cylinder and one of those port-a-power hand pumps. I took one side of the cylinder and filled it with grease, on the other side of the cylinder I attached the hose from the hand pump. I would then attach a hose from the grease packed side of the cylinder to the fitting hole. You'd have to remove the fitting and attach the hose directly into the fitting hole, as the fitting wouldn't hold the pressure. The hand pump was capable of applying 10,000 psi, and would force the grease into the joint.
It worked really well until I finally destroyed the cylinder, because it wasn't rated for 10K psi, but I freed up several stuck fittings before it broke.

I did this with a porta power,hooked up a steel break line up to the threaded zerk hole an pushed hyd oil in to it.it was on spring pins. some took some did not, ended up replacing pins

Spring pins seem like the worst, I guess they catch lots of road grime and whatnot.

I've found it really helps to grease the springs more frequently than you grease the rest of the truck. It seems to help keep them free.
