bx LA 243 loader grease zerks

[TMGT]

I was thinking pull the pin out enough to tap it all the way through, pin doesn't have to come all the way out.

I have had success making a "tap" out of an old zerk.

I use a dremel and cut two or more slots across the zerk.

The slots help the fitting cut new threads with the slots providing a place for metal flakes to go.

Once you get it started back it out and clean of flakes often and then install new zerk.

The zerk thread is likely a tapered pipe thread not a regular straight bolt thread. A tapered thread is often called a pipe thread where you wrap the threads with Teflon tape before screwing together.

This link may help you to identify which zerk you have.

I have seen zerks which are pressed in not threaded I guess because it is cheaper to make but no fun when plugged or damaged.

All the fittings on the 3 Kubota's I have are straight thread, one is a BX1500, I can't remember the size for the loader fittings off the top of my head though.

There are different size grease zerks on the loader but I figured out that the one I need to change is 1/4 UNF which I think is the same as 1/4-28. I would assume all the grease zerks on the loader are American or the unified system rather than metric.

I think the first thing I will try is to get a 1/4-28 tap and some new 1/4-28 grease zerks. If that doesn't work then going up to the next size of 5/16 UNF should work.

Have a grease fitting tool that removes, extracts, and taps most grease fittings.

I got a 1/4 28 tap and was able to tap it and put a new zerk in. It works so I guess that it's good enough for now.

There is another zerk on the loader that will take grease if I unscrew it some from the threads, but when it is snugged into the threads it does not.

Keep in mind, if it is a new machine some may be hard to grease until you use it a bit because of the tight tolerances. Glad you got your grease fitting fixed though!
