Grease fitting problem

[Agrantina]

This is a older atlas disc, not sure what series? The lower left grease fitting in this picture is jammed. Tried heat and air pressure to clear but no luck. It does not have a typical bolt head so HOW do I remove and replace? Is it tapped or pressed in? What other ways can I try to clear it? I heard about the tool but was wondering if they are worth the money??

If it were mine I would first try grinding some flats on each side of the nipple for a wrench. If that failed and a welder was available I would weld a nut over the nipple. Last choice would be a drill, easy out, and a pipe tap.

So these are threaded in? just dont have a nut head like newer ones?

The type you have is "tap in style"....they predrill holes (usually 3/16")....then tap grease fitting in.....You can drill it out and tap to 1/4-28 or 1/8 npt and install new ones....

The cleaner I use at work is here...Alemite 339841 Zerk-Mate Grease Fitting / Joint Cleaner, Grease guns, Cordless grease guns, Battery powered grease guns, Grease pumps, Liquid Filled Pressure gauges, Hydraulic pressure gauges, Paintball gauges, Custom pressure gauges, Flashlight, Too

Cheaper ones are out there.....Harbor Freight or Northern Tool...

It's probably threaded in. Pressed zerks without a nut are the new thing. The older zerks are the tapped kind with a nut on them. The nut part is probably worn or rusted off.

I've seen "Tap in Style" since about the early seventies, they were just a cheaper way to install.....drill a hole and drive it in......these grease fittings had ribs on them, kinda like flooring nails.....

You can sometimes get a fitting to take grease by forcing motor oil into it. Take the plunger back and lock it into place. Remove the head off the grease gun as if you were putting a new tube in. Instead pour alittle oil on top of the grease. Put the gun back together. The grease gun will now be pushing pressurized oil into the fitting,often clearing out the zerk enough to take grease. Worth a try.
