1979 Ford 1300 Front Axle Removal

[mag944]

Moving this post from general discussion, hoping to find some help as I am new to posting on this forum. Recently purchased a 1979 Ford 1300 (Shibuara) tractor. Very good condition overall and everything checks out except for some play in the front axle. I want to check the shims but I can't get either the front or rear piovt shaft covers off. These are the covers that have two bolts and a grease nipple in the center. Is there a trick I've missed because brute force isn't working.
Thanks in advance for your assistance.

I've been into a 1220 and a 1700 front end.. but never a 1300 or apparrently a 1500 that it shares commonality with.

here's a parts listing and diagram of that front end.. rear cap looks fairly straight forward.. any chance of getting an impact wrench on them? ive seen an impact loosen bolts that would otherwise shear off on a straight pull. also dousing with penetrant oil and a whack to teh head with a hammer to swage the threads a bit sometimes helps. if you can get penetrant to the back it would help.. but probably not likely on this design.
