Any one know what size grease zerk the MT240 needs?

I thought I had read on here that the MT2 tractors/loaders/backhoes used an odd grease zerk, maybe BSP? but can't find the information using the search function.

Yes, they are BSP. Very hard, if not impossible to find out here in my part of the country..... I had the dealer send 10 of them to me. I haven't had to replace any yet....

I got them from RCO tractor in Austin

I had to replace a couple on my LS-branded backhoe, and they were an M6 thread. I got an assortment of them from Harbor Freight for a few bucks. I don't know if they have changed for the newer tractor models.

All the zerks on my machine, that I've had to replace, are 1/8in pipe

I ordered these and picked them up yesterday. 10 for $6.25

KINGFISHER 1'/'8"-28-BSPT Straight Head Angle, Standard Grease Fitting, Zinc-Plated Steel, 39'/'64 inL, 8,??? psi, - 3ANZ2'|'3ANZ2 - Grainger

It looked like a perfect match to the broke one I removed and seemed to install ok, was a little tighter after 1 turn then I would have liked so I removed it and inspected and no cross threading that I could see. I went ahead and installed it snug and greased it with no leaking.

It's deceiving because the threaded barrel is closer to 1/2" diameter and I couldn't find any specs online for them prior to ordering so thought maybe 1/8" was the smaller one but it wasn't.
