[AT] Bad grease fitting

[jtchall at nc.rr.com]

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.
