I've had one with dried grease dirt and had to dig it out with a small wire. I scratched as much dirt out as I could, with a small 'L' shaped wire. Then I filled the hole with Liquid Wrench and scratched out some more dirt each day, refilling with oil afterwards and plugging the hole with a zerk to hold the oil in. I also soaked the ends of the pins each time and rotated them as J J describes, to let the oil soak the joint. After a few days you should be able to add a new zerk and try the grease pressure again, while rotating the spindle. It sounds like a long process but only takes a couple of minutes per day.

Maybe some heat applied might free it up . Could even freeze it with CO2.
There was another product that worked better than all others for loosening things , and was made up with equal parts of Acetone, ATF, and something else. You made it up in small batches, could not store it very long.

Just about any of the manual hydraulic jacks use hydraulic hose with a 10 k rating, and I am thinking that 1/4 in hyd hose has a high rating also.

Will any parts store have high pressure lines like you used?
I just used a grease gun hose with an adapter to match the output of the portapower pump. My desire was to get something thinner than grease flushed through. If you filled the hose with Kroil or some other penetrant and forced that through it would be best.
BTW that Kroil really does penetrate well, I have two 8oz squeeze cans of it, one on my reloading bench and one in the garage...they both are leaking out the bottom seams of the cans

A grease gun can put up as much as 5ooo# .
You might try heating the part with a torch while trying to grease it.

YOu can try the zerk cleaner as mentioned previously. They can work.
You may want to upgrade your grease gun. Better guns are in the 7-10k psi range. I have a linclon 1134 (7k?) and ive used it to get grease into zerks that lower pressure guns couldnt but ymmv.
And Kroil really is great stuff.

As others have said, use a good quality grease gun with a high psi output, some are advertised to reach 10,000 psi! I personally wouldn't bother with tractor hydraulics but I really really like the idea of a Port-a-Power pump to force a good penetrating oil into the fitting! Heating the sleeve good and hot will definitely help also as it has the benefit of expanding the sleeve while it turns whatever grease is in there liquidy again, well...as much as possible anyways. BE DARN CAREFUL OF APPLYING A FLAME TO THE SLEEVE WHILE PUMPING IN FLAMMABLE LIQUID!!! It would be alot safer to do the two things seperately.

I had a zerk on my backhoe that wouldn't take grease. I ended up disassembling that knuckle, removed the zerk, and found a dead-ended hole. After drilling the zerk hole all the way through and cleaning up the burrs it took grease just fine.
