Kubota zerk grease fitting size

Interesting, the fittings on my MX5100 and the LA844 loader are all the same SAE. I bought the tractor and loader in August of 2011.

I bought the harbor freight sets and there was not a match for the zerks on my LA724 loader.

Do you know what they are? I have one on an LA844 that needs replaced.

I think I remember reading that some of the zerks were tapered as opposed to straight. Not sure if that makes a difference.

One of the zerks fell out of my BH92 while greasing. I tried for 15 minutes to get it back in and couldn't. My buddy stopped by and I had him try to get it in and he couldn't.
I got my assortment of zerks and tried metric, which was wrong and 1/4-28 and none would go in. I knew it wasn't metric, so it had to be 1/4-28.
I got my 1/4-28 tap and I knew I had to be careful (I'm not a mechanic) so I didn't cross thread the tap and screw it up. Cleaned up the threads and it went in fine.
Now I know the BH and FEL are 1/4-28 and the tractor is metric.

Update from the OP:

The Harbor Freight standard and metric Zerk sets don't have the correct size for my tractors' (and neighbor's) FELs. All of them take a 8mm x 1.25 Zerk.

A few 10-packs were bought online from McMaster-Carr and Zoro and they work perfectly in the FELs. Haven't had a need to replace any of the Zerks on any of the tractors (yet).

Try Amazon they have assorted zerk kits

I haven't been able to get the zerk on a G1800 front PTO shaft to take grease. Finally backed it out a few turns and it took grease. I think the threads are too long and it is up against the shaft so no grease can go in. I found this with suggest different thread lenghts for grease fittings. Going to grind down the current one or find one with shorter threads. Just componds the problem with getting one. The G1800 parts diagram doesn't even show a grease fitting, so I guess Kubota just replaces it with one off their shelf.

Rather than grind it down, why not just put a lock washer under it?
