Grease Fitting Problem

I have a problem with some grease fittings that are plugged up. The fittings are not the problem since I can remove them and pump grease through them. But when I put them back in my grease gun will just not pump anything through them.

I purchased one of those grease fitting cleaners. It's the kind you fill with penetrating oil then put on the fitting and strike it with a hammer to inject the penetrating oil. Even this does nothing. I have tried repeatedly but it doesn't work. These grease fittings are on the bottom of my front spindles. You can see one of the fittings I'm talking about in the first picture. The second picture shows the fittings on the top of the spindles. These work correctly.

The funny thing is that the parts book drawing does not show those bottom grease fittings. It only shows the top ones as you see in #3 in the last picture. Anyone have any ideas?

By the way, this is a MF202.

I have seen times when old grease is rock hard in back of the fittings and has to be dug out with a
drill bit or small screwdriver.

It just seems kind of strange that the top fittings on both sides are fine but the bottom fittings on both sides are plugged up. Surely if someone bothers to lube the spindles they would do the bottom ones too. They're like nine inches apart and in plain site.

I'm still wondering why the parts book doesn't show a fitting on the bottom. Will one of you 202 owners please confirm that you have fittings on the bottom of the spindles as well as the top?
 

Where does that fitting go? It looks like it's in where there would have been a center drill to turn the spindle forging before it got welded to the upright shaft. Does that fitting actually go somewhere or is it a ruse? I'd start taking it apart to see where it goes, and possibly try sticking a drill bit in there to clear out any possible hard grease.

Something just doesn't look right.

I have a keyless chuck that I took off a non working drill motor. I put a small drill bit in that and stuck it in the hole. turning it by hand. It just feels like solid metal in there. I'm beginning to think you are on the right track. That why I asked other 202 owners to look at their machines and see if there are zerk fittings there on theirs. I know there are at least two 202 owners here.
 

Looking at my 8N just now, I see that there is only one grease fitting and it is in the middle of the spindle housing.

On the 202 the fitting is about two inches from the top. So, what I'm planning is cleaning the grease around the top joint and wrapping some plastic wrap around it. Then I will have someone hold it the best they can while I pump grease into it. I'm hoping this will force the grease to head to the bottom and I'll see it coming out, that is if it's supposed to work like the 8N does.

Trouble is that I have to get some more grease cartridges next time I go to town. I'll let you guys know how it works out.
 
On our tractors, if you took the weight off of it, the grease could find it's way down easier.
