Power Steering Ram, Clutch Housing Grease

So, I got my 64 Super Major a few weeks ago and ran it a little bit then put it in the car port. I dont think its wise to run it before I change the fluids and filters but I did fish out the old grease gun and hit all the zerks I could find. The manual I had didnt have a listing of the zerks but the one I got in the mail does have a diagram. So, Ill be doing a triple re-check to make sure I havent missed any. I did come across a couple of issues that I would like to make sure I get some feedback on before I proceed. 1) On the power steering ram there are 2 zerks; one is on the very front of the cylinder and the other one is further back on the top. 2) There is a zerk in the housing where the clutch pedal/rod assembly enters the housing. Ill try to get some pictures linked below. My concerns are that when I was greasing the zerk on the front of the cylinder I gave it 5 or 6 pumps there was no increased pressure. I looked around to see if there was any grease being expelled or pushed out somewhere by the zerk. Seeing no grease pushing out anywhere I gave it a few more pumps and still no visible grease being pushed out. I figured that either the old crusty grease was so hard that no new grease was able to push the old out of the way or the machine and no grease in the bearing. I figured I would move on to the other zerk and maybe the first one to show some grease after some time. While greasing the second zerk, again 5 or 6 pumps there was no sign of any old grease being displaced. Given that I wasnt sure exactly how much grease these almost 60-year-old cylinders take I figured I would stop until I could find some better information. Additionally, I dont want to push grease passed that backing plates, and mix grease and hydraulic fluids. I moved on to the zerk for the clutch, while cleaning the zerk off, I had the same thought so I looked at the manual I had. That old manual 1958? Described grease in a cup and turning the lid down turn. The more recent manual doesnt show I zerk in the housing. So here I am; asking if anyone could share some insights.

The greasers on the clutch shaft only need a couple of pumps per week otherwise all you
will do is push grease into the clutch housing. It will not hurt as it is a big empty
space but you are wasting grease.

The stuffer cap is for tractors with the heavy duty 13 clutch and thrust bearing so
if you do not have it, you have a normal clutch.

The power steering ram greasers just lubricate the ball joint, again a couple of pumps
per week is fine.

Thanks!
