Maybe it would be easier to put in a 1/4-28 fitting? I have been known to
jack up a front end to get the load off to try to get fittings to take
grease. We had a 60's farm truck once that we would warm the rear springs
with a torch so they would take grease. I normally use a hand gun but for
some stubborn fittings I use an air gun.

Subject: [AT] Bad grease fitting
I've got an ongoing problem with a grease fitting on the front axle pivot of
a MF 255. When I got the tractor, the fitting was missing (19 years
ago....). I put one in, but it fell out before the next service, the
threads were stripped. Being a poor young guy back then, I put JB weld on a
new fitting, put it in the threads till it was snug and let it set up. All
was fine till the past few services, at first it was hard to get it to take
grease, now it won't take any at all.
The problem is the shoulders of the fitting sit down in a hole in the
casting, probably deeper than original since the threads were bad and I
can't get on it to get it out. This is a 1/4 NPT straight fitting. My
thought is to grind off the tit, pull out the spring, drill and tap the old
fitting for a new 1/8 NPT fitting, clean out and hard grease and start
over.
Any predictions of this working? If the old fitting falls out during the
grinding/drilling, I'll do a helicoil fix.
