Hub cap Zerks

Any advise or experience on this? I am trying to get things as much original as possible but to do this on the hubs would require grinding off the zerks and re-drilling and threading for something that seems uneccessary or damaging.

Replacement hubs for tractors and implements can be bought with or without zerks, not necessarily in the caps.

In my 4020 owner's manual, it recommends the hubs be removed and thoroughly cleaned at the specified intervals, but inbetween should the wheels be submerged above the hub caps that they be conveniently and rapidly purged of water by filling through the zerks.

Ferguson's don't really have a lip type seal but just a flat rubber washer sort of device so forcing grease thru it won't damage the so called seal. This is the first "thing" I have worked on that uses such a device for a seal.

Anyway my question was not answered as to the use of a zerk fitting in the hub cap. The parts manual does not show a zerk in the cap.

When I originally mentioned Hub caps and Zerks, I did not expect wheel covers and a story on those. I have no idea why someone would want wheel covers on a tractor although there are tractors that the wheel design inludes a cover as part of the wheel.

Maybe modern yokes don't know about greasing bearings but seeing a Zerk is also meaningless as almost no cars use these any more. Bearing and packing is still a current art. We are part of the lost generations when it comes to zerks. I have an airplane and I much prefer to pack bearings as I can see what is inside and that ALL IS WELL. Shoving grease thru a zerk offers not a clue as to the insides of the wheel other than it is hollow when grease comes out the back side.

I convert many axles to this style of grease zerks. I really perfer this system; they have worked on a horse trailer, used it for 30 years, vacation trailers, tractors and more. Never a bearing failure in over 30 years....
Good luck

Mine had much larger than normal type and both were damaged bad. I ground them off flush with the cap and looks like they may have been threaded in. Still debating whether to weld them shut or extract them and replace with American style standard zerk.
